+# Ghost MCP - Docker Development Setup
+
+This guide helps you set up a Ghost instance for Ghost MCP development and API investigation.
+
+## Quick Start
+
+1. **Copy environment file**:
+   ```bash
+   cp .env.example .env
+   ```
+
+2. **Start Ghost and MySQL**:
+   ```bash
+   docker compose up -d
+   ```
+
+3. **Access Ghost**:
+   - Ghost Admin: http://localhost:2368/ghost
+   - Ghost Site: http://localhost:2368
+   - phpMyAdmin (optional): http://localhost:8080
+
+## Services
+
+### Ghost (Main Service)
+- **Image**: `ghost:5-alpine`
+- **Port**: 2368
+- **URL**: http://localhost:2368
+- **Admin**: http://localhost:2368/ghost
+
+### MySQL Database
+- **Image**: `mysql:8.0`
+- **Database**: `ghost_dev` (configurable via .env)
+- **User**: `ghost` (configurable via .env)
+
+### phpMyAdmin (Optional Debug Tool)
+- **Image**: `phpmyadmin/phpmyadmin:latest`
+- **Port**: 8080
+- **Access**: http://localhost:8080
+
+To start with phpMyAdmin for database debugging:
+```bash
+docker compose --profile debug up -d
+```
+
+## Initial Setup
+
+### 1. First-time Ghost Setup
+1. Start the services: `docker compose up -d`
+2. Wait for Ghost to initialize (check logs: `docker compose logs ghost`)
+3. Visit http://localhost:2368/ghost
+4. Create your admin account
+5. Complete the Ghost setup wizard
+
+### 2. Obtain API Keys
+1. In Ghost Admin, go to Settings → Integrations
+2. Click "Add custom integration"
+3. Give it a name (e.g., "MCP Development")
+4. Copy both API keys:
+   - **Content API Key**: For read-only operations
+   - **Admin API Key**: For read/write operations
+
+### 3. Update Environment (Optional)
+Add the API keys to your `.env` file:
+```bash
+GHOST_CONTENT_API_KEY=your_content_api_key_here
+GHOST_ADMIN_API_KEY=your_admin_api_key_here
+```
+
+## API Testing
+
+### Content API (Read-only)
+Test the Content API with curl:
+```bash
+# Get all posts
+curl "http://localhost:2368/ghost/api/content/posts/?key=YOUR_CONTENT_API_KEY"
+
+# Get site settings
+curl "http://localhost:2368/ghost/api/content/settings/?key=YOUR_CONTENT_API_KEY"
+```
+
+### Admin API (Read/Write)
+The Admin API requires JWT authentication. You'll need to generate a JWT token using your Admin API key.
+
+## Management Commands
+
+### Start services
+```bash
+docker compose up -d
+```
+
+### Stop services
+```bash
+docker compose down
+```
+
+### View logs
+```bash
+# All services
+docker compose logs
+
+# Ghost only
+docker compose logs ghost
+
+# Follow logs
+docker compose logs -f ghost
+```
+
+### Reset everything (⚠️ Destroys all data)
+```bash
+docker compose down -v
+docker volume rm ghost_mcp_content ghost_mcp_mysql
+```
+
+### Backup data
+```bash
+# Create backup of Ghost content
+docker run --rm -v ghost_mcp_content:/data -v $(pwd):/backup alpine tar czf /backup/ghost-content-backup.tar.gz -C /data .
+
+# Create backup of MySQL data
+docker run --rm -v ghost_mcp_mysql:/data -v $(pwd):/backup alpine tar czf /backup/mysql-backup.tar.gz -C /data .
+```
+
+## Troubleshooting
+
+### Ghost won't start
+1. Check if MySQL is healthy: `docker compose ps`
+2. Check Ghost logs: `docker compose logs ghost`
+3. Verify environment variables in `.env`
+
+### Can't access Ghost admin
+1. Ensure Ghost is running: `docker compose ps`
+2. Check if port 2368 is available: `netstat -an | grep 2368`
+3. Try accessing directly: http://localhost:2368/ghost
+
+### Database connection issues
+1. Check MySQL health: `docker compose logs ghost-db`
+2. Verify database credentials in `.env`
+3. Ensure database has started before Ghost
+
+### API requests failing
+1. Verify API keys are correct
+2. Check Content API: should work with query parameter
+3. Check Admin API: requires proper JWT token generation
+
+## Development Notes
+
+- Ghost data persists in named Docker volumes
+- Database is accessible via phpMyAdmin at localhost:8080
+- All Ghost content (themes, images, etc.) is stored in the `ghost_content` volume
+- MySQL data is stored in the `ghost_mysql` volume
+- Environment variables are loaded from `.env` file
+
+## Next Steps
+
+Once Ghost is running, you can:
+1. Create test content (posts, pages, tags)
+2. Test API endpoints
+3. Begin MCP server development
+4. Investigate Ghost API authentication flows
+
+For MCP development, see the main project documentation.

+# Ghost Admin API JWT Authentication Documentation
+
+## Overview
+Ghost Admin API uses JWT (JSON Web Token) authentication for secure, server-side access to read/write operations.
+
+## Authentication Flow
+
+### 1. API Key Structure
+**Format**: `{id}:{secret}`
+- **ID**: Used as the `kid` (key identifier) in JWT header
+- **Secret**: Used to sign the JWT token
+- **Source**: Generated from Ghost Admin → Settings → Integrations → Custom Integration
+
+**Example**: `507f1f77bcf86cd799439011:1234567890abcdef1234567890abcdef12345678`
+
+### 2. JWT Token Generation
+
+#### Required Headers
+```json
+{
+  "alg": "HS256",
+  "kid": "{api_key_id}",
+  "typ": "JWT"
+}
+```
+
+#### Required Payload
+```json
+{
+  "exp": {timestamp_plus_5_minutes},
+  "iat": {current_timestamp},
+  "aud": "/admin/"
+}
+```
+
+#### Constraints
+- **Token Expiration**: Maximum 5 minutes from generation
+- **Algorithm**: HS256 (HMAC SHA-256)
+- **Audience**: Must be `/admin/`
+- **Key ID**: Must match the API key ID
+
+### 3. HTTP Request Format
+
+#### Required Headers
+```http
+Authorization: Ghost {jwt_token}
+Accept-Version: v5.0
+Content-Type: application/json
+```
+
+#### Example Request
+```http
+GET /ghost/api/admin/posts/ HTTP/1.1
+Host: localhost:2368
+Authorization: Ghost eyJhbGciOiJIUzI1NiIsImtpZCI6IjUwN2YxZjc3YmNmODZjZDc5OTQzOTAxMSIsInR5cCI6IkpXVCJ9...
+Accept-Version: v5.0
+```
+
+## Implementation Requirements
+
+### Node.js Implementation (for MCP Server)
+
+#### Dependencies
+```json
+{
+  "jsonwebtoken": "^9.0.0"
+}
+```
+
+#### Token Generation Function
+```javascript
+const jwt = require('jsonwebtoken');
+
+function generateAdminApiToken(apiKey) {
+  // Split the key into ID and secret
+  const [id, secret] = apiKey.split(':');
+
+  // Prepare header
+  const header = {
+    alg: 'HS256',
+    kid: id,
+    typ: 'JWT'
+  };
+
+  // Prepare payload
+  const now = Math.floor(Date.now() / 1000);
+  const payload = {
+    exp: now + (5 * 60), // 5 minutes from now
+    iat: now,
+    aud: '/admin/'
+  };
+
+  // Generate token
+  const token = jwt.sign(payload, Buffer.from(secret, 'hex'), { header });
+  return token;
+}
+```
+
+#### Usage Example
+```javascript
+const adminApiKey = 'your_admin_api_key_here';
+const token = generateAdminApiToken(adminApiKey);
+
+const response = await fetch('http://localhost:2368/ghost/api/admin/posts/', {
+  headers: {
+    'Authorization': `Ghost ${token}`,
+    'Accept-Version': 'v5.0',
+    'Content-Type': 'application/json'
+  }
+});
+```
+
+### Token Refresh Strategy
+Since tokens expire after 5 minutes:
+1. **Generate new token for each request** (simplest)
+2. **Cache token with expiration tracking** (more efficient)
+3. **Regenerate on 401 response** (error-driven)
+
+### Recommended Approach for MCP Server
+```javascript
+class GhostAdminAuth {
+  constructor(apiKey) {
+    this.apiKey = apiKey;
+    this.token = null;
+    this.tokenExpiry = null;
+  }
+
+  generateToken() {
+    const [id, secret] = this.apiKey.split(':');
+    const now = Math.floor(Date.now() / 1000);
+
+    const payload = {
+      exp: now + (4 * 60), // 4 minutes (buffer)
+      iat: now,
+      aud: '/admin/'
+    };
+
+    this.token = jwt.sign(payload, Buffer.from(secret, 'hex'), {
+      header: { alg: 'HS256', kid: id, typ: 'JWT' }
+    });
+    this.tokenExpiry = now + (4 * 60);
+
+    return this.token;
+  }
+
+  getValidToken() {
+    const now = Math.floor(Date.now() / 1000);
+    if (!this.token || now >= this.tokenExpiry) {
+      return this.generateToken();
+    }
+    return this.token;
+  }
+
+  getAuthHeaders() {
+    return {
+      'Authorization': `Ghost ${this.getValidToken()}`,
+      'Accept-Version': 'v5.0',
+      'Content-Type': 'application/json'
+    };
+  }
+}
+```
+
+## Error Handling
+
+### Invalid Token
+**Response**: 401 Unauthorized
+```json
+{
+  "errors": [
+    {
+      "message": "Authorization failed",
+      "context": "Unable to determine the authenticated user or integration...",
+      "type": "UnauthorizedError"
+    }
+  ]
+}
+```
+
+### Expired Token
+**Response**: 401 Unauthorized
+**Action**: Generate new token and retry
+
+### Invalid API Key
+**Response**: 401 Unauthorized
+**Action**: Verify API key format and permissions
+
+## Security Considerations
+
+1. **Keep API Key Secret**: Never expose in client-side code
+2. **Server-Side Only**: JWT generation must happen server-side
+3. **Short Token Lifespan**: Maximum 5 minutes reduces exposure window
+4. **HTTPS in Production**: Always use HTTPS for API requests
+5. **Key Rotation**: Regularly rotate API keys in production
+
+## Testing Strategy
+
+### Manual Testing
+1. Generate API key from Ghost Admin
+2. Create JWT token using the implementation
+3. Test various Admin API endpoints
+4. Verify token expiration handling
+
+### Automated Testing
+1. Mock JWT generation for unit tests
+2. Use test API keys for integration tests
+3. Test token refresh logic
+4. Test error handling scenarios
+
+## Implementation Status
+- ✅ Authentication flow documented
+- ✅ JWT generation requirements identified
+- ✅ Node.js implementation planned
+- ⏳ Implementation pending API key generation
+- ⏳ Testing pending API key availability

+      "message": "Resource not found",
+      "type": "NotFoundError"
+    }
+  ]
+}
+```
+
+## Security Considerations
+
+### Safe for Public Use
+- Content API keys only access published content
+- No sensitive data exposure
+- Can be used in browsers, mobile apps, etc.
+
+### Private Sites
+- Be cautious with key distribution on private Ghost sites
+- Consider access restrictions if content should be limited
+
+### Key Management
+- Keys can be regenerated in Ghost Admin
+- Multiple integrations can have different keys
+- Monitor key usage if needed
+
+## Rate Limiting & Caching
+
+### Caching Behavior
+- Content API responses are fully cacheable
+- Cache headers provided in responses
+- Recommended to implement caching in client
+
+### Rate Limiting
+- No strict rate limits documented
+- Reasonable usage expected
+- Monitor response times and adjust accordingly
+
+## Testing Strategy
+
+### Manual Testing

+# Ghost Content Formats Documentation
+
+## Overview
+Ghost supports multiple content formats for creating and managing posts and pages. Understanding these formats is crucial for proper MCP tool implementation.
+
+## Content Format Evolution
+
+### Historical Context
+1. **Mobiledoc** (Legacy): Ghost's previous JSON-based content format
+2. **HTML**: Traditional markup format
+3. **Lexical** (Current): Ghost's current standardized JSON content format
+
+## Current Content Formats
+
+### 1. Lexical Format (Primary)
+**Status**: Current standard format
+**Type**: JSON-based structured content
+**Usage**: Default format for all new content
+
+#### Structure
+```json
+{
+  "lexical": "{\"root\":{\"children\":[{\"children\":[{\"detail\":0,\"format\":0,\"mode\":\"normal\",\"style\":\"\",\"text\":\"Welcome to Ghost!\",\"type\":\"text\",\"version\":1}],\"direction\":\"ltr\",\"format\":\"\",\"indent\":0,\"type\":\"paragraph\",\"version\":1}],\"direction\":\"ltr\",\"format\":\"\",\"indent\":0,\"type\":\"root\",\"version\":1}}"
+}
+```
+
+#### Benefits
+- Rich content representation
+- Structured, parseable format
+- Supports complex layouts and content blocks
+- Platform-agnostic content storage
+
+### 2. HTML Format (Optional)
+**Status**: Available for output/input
+**Type**: Rendered HTML markup
+**Usage**: For compatibility and direct HTML input
+
+#### Structure
+```json
+{
+  "html": "<p>Welcome to Ghost!</p><p>This is a simple HTML paragraph.</p>"
+}
+```
+
+#### Use Cases
+- Content migration from HTML-based systems
+- Direct HTML content creation
+- Output for web rendering
+
+### 3. Mobiledoc Format (Legacy)
+**Status**: Legacy support (deprecated)
+**Type**: JSON-based (older format)
+**Usage**: Existing content only
+
+**Note**: New content should use Lexical format. Mobiledoc is maintained for backward compatibility.
+
+## API Content Handling
+
+### Content Retrieval
+
+#### Default Behavior
+- API returns Lexical format by default
+- HTML format requires explicit request
+
+#### Format Selection
+```javascript
+// Get only Lexical (default)
+GET /ghost/api/content/posts/
+
+// Get both Lexical and HTML
+GET /ghost/api/content/posts/?formats=html,lexical
+
+// Get only HTML
+GET /ghost/api/content/posts/?formats=html
+```
+
+#### Response Examples
+
+**Lexical Only (Default)**:
+```json
+{
+  "posts": [
+    {
+      "id": "post_id",
+      "title": "My Post",
+      "lexical": "{\"root\":{...}}",
+      "slug": "my-post"
+    }
+  ]
+}
+```
+
+**HTML and Lexical**:
+```json
+{
+  "posts": [
+    {
+      "id": "post_id",
+      "title": "My Post",
+      "lexical": "{\"root\":{...}}",
+      "html": "<p>Post content</p>",
+      "slug": "my-post"
+    }
+  ]
+}
+```
+
+### Content Creation & Updates
+
+#### Admin API Content Fields
+```javascript
+// Creating a post with Lexical
+const postData = {
+  posts: [{
+    title: "New Post",
+    lexical: JSON.stringify(lexicalContent),
+    status: "draft"
+  }]
+};
+
+// Creating a post with HTML
+const postData = {
+  posts: [{
+    title: "New Post",
+    html: "<p>HTML content here</p>",
+    status: "draft"
+  }]
+};
+
+// Creating with both (Lexical takes precedence)
+const postData = {
+  posts: [{
+    title: "New Post",
+    lexical: JSON.stringify(lexicalContent),
+    html: "<p>Fallback HTML</p>",
+    status: "draft"
+  }]
+};
+```
+
+## Content Format Priorities
+
+### Create/Update Priority Order
+1. **Lexical** (highest priority)
+2. **HTML** (fallback if no Lexical)
+3. **Mobiledoc** (legacy fallback)
+
+### Conversion Behavior
+- HTML → Lexical: Ghost converts HTML to Lexical automatically
+- Lexical → HTML: Ghost renders Lexical to HTML
+- Mobiledoc → Lexical: Ghost migrates existing Mobiledoc content
+
+## Implementation for MCP Server
+
+### Content Format Detection
+```javascript
+class GhostContentHandler {
+  detectContentFormat(content) {
+    if (typeof content === 'object' && content.root) {
+      return 'lexical';
+    }
+    if (typeof content === 'string' && content.startsWith('<')) {
+      return 'html';
+    }
+    if (typeof content === 'object' && content.version) {
+      return 'mobiledoc';
+    }
+    return 'unknown';
+  }
+
+  prepareContentForAPI(content, preferredFormat = 'lexical') {
+    const format = this.detectContentFormat(content);
+
+    switch (format) {
+      case 'lexical':
+        return {
+          lexical: typeof content === 'string' ? content : JSON.stringify(content)
+        };
+      case 'html':
+        return {
+          html: content
+        };
+      case 'mobiledoc':
+        return {
+          mobiledoc: typeof content === 'string' ? content : JSON.stringify(content)
+        };
+      default:
+        // Assume plain text, wrap in HTML
+        return {
+          html: `<p>${content}</p>`
+        };
+    }
+  }
+}
+```
+
+### MCP Tool Content Parameters
+
+#### Create Post Tool
+```javascript
+const createPostTool = {
+  name: "ghost_admin_create_post",
+  parameters: {
+    title: { type: "string", required: true },
+
+    // Content format options (one required)
+    lexical: { type: "string", description: "Lexical JSON content" },
+    html: { type: "string", description: "HTML content" },
+    mobiledoc: { type: "string", description: "Mobiledoc JSON content (legacy)" },
+
+    // Other parameters...
+    status: { type: "string", enum: ["draft", "published"] }
+  }
+};
+```
+
+#### Content Validation
+```javascript
+function validateContentInput(params) {
+  const contentFormats = ['lexical', 'html', 'mobiledoc'].filter(
+    format => params[format] !== undefined
+  );
+
+  if (contentFormats.length === 0) {
+    throw new Error('At least one content format (lexical, html, or mobiledoc) is required');
+  }
+
+  if (contentFormats.length > 1) {
+    console.warn('Multiple content formats provided. Lexical will take precedence.');
+  }
+
+  // Validate Lexical JSON if provided
+  if (params.lexical) {
+    try {
+      JSON.parse(params.lexical);
+    } catch (error) {
+      throw new Error('Invalid Lexical JSON format');
+    }
+  }
+
+  return true;
+}
+```
+
+## Content Format Examples
+
+### 1. Simple Lexical Content
+```json
+{
+  "root": {
+    "children": [
+      {
+        "children": [
+          {
+            "detail": 0,
+            "format": 0,
+            "mode": "normal",
+            "style": "",
+            "text": "Hello World!",
+            "type": "text",
+            "version": 1
+          }
+        ],
+        "direction": "ltr",
+        "format": "",
+        "indent": 0,
+        "type": "paragraph",
+        "version": 1
+      }
+    ],
+    "direction": "ltr",
+    "format": "",
+    "indent": 0,
+    "type": "root",
+    "version": 1
+  }
+}
+```
+
+### 2. Rich HTML Content
+```html
+<h1>My Blog Post</h1>
+<p>This is a <strong>rich</strong> HTML post with <em>formatting</em>.</p>
+<ul>
+  <li>First item</li>
+  <li>Second item</li>
+</ul>
+<blockquote>
+  <p>This is a quote block.</p>
+</blockquote>
+```
+
+### 3. Content Conversion Utility
+```javascript
+class ContentConverter {
+  // Convert HTML to simple Lexical
+  htmlToLexical(html) {
+    // Basic implementation - in practice, use Ghost's conversion utilities
+    const paragraphs = html.split('</p>').filter(p => p.trim());
+    const children = paragraphs.map(p => {
+      const text = p.replace(/<[^>]*>/g, '').trim();
+      return {
+        children: [{
+          detail: 0,
+          format: 0,
+          mode: "normal",
+          style: "",
+          text: text,
+          type: "text",
+          version: 1
+        }],
+        direction: "ltr",
+        format: "",
+        indent: 0,
+        type: "paragraph",
+        version: 1
+      };
+    });
+
+    return {
+      root: {
+        children: children,
+        direction: "ltr",
+        format: "",
+        indent: 0,
+        type: "root",
+        version: 1
+      }
+    };
+  }
+
+  // Convert Lexical to simple HTML
+  lexicalToHtml(lexical) {
+    const content = typeof lexical === 'string' ? JSON.parse(lexical) : lexical;
+    const paragraphs = content.root.children.map(child => {
+      if (child.type === 'paragraph') {
+        const text = child.children.map(textNode => textNode.text).join('');
+        return `<p>${text}</p>`;
+      }
+      return '';
+    });
+    return paragraphs.join('\n');
+  }
+}
+```
+
+## Best Practices
+
+### For MCP Implementation
+1. **Default to Lexical**: Use Lexical format for new content creation
+2. **Support HTML Input**: Allow HTML for ease of use and migration
+3. **Validate JSON**: Always validate Lexical JSON before sending to API
+4. **Handle Conversion**: Provide utilities for format conversion if needed
+5. **Graceful Fallback**: Handle legacy Mobiledoc content gracefully
+
+### Content Creation Guidelines
+1. **Use Lexical for Rich Content**: Complex layouts, cards, embeds
+2. **Use HTML for Simple Content**: Basic text formatting
+3. **Provide Format Options**: Let users choose their preferred input format
+4. **Validate Before Submission**: Check content validity before API calls
+

+# Ghost API Filtering Syntax Documentation
+
+## Overview
+Ghost uses NQL (Node Query Language) for filtering API results. This provides powerful querying capabilities for both Content and Admin APIs.
+
+## Basic Syntax
+
+### Property-Operator-Value Format
+```
+property:operator value
+```
+
+### Simple Examples
+```
+status:published          # Posts with published status
+featured:true             # Featured posts only
+slug:welcome              # Post with slug "welcome"
+tag:news                  # Posts tagged with "news"
+```
+
+## Operators
+
+### 1. Equality (Default)
+**Operator**: `:` (colon)
+**Usage**: Exact match
+```
+status:published
+featured:true
+author:john-doe
+```
+
+### 2. Negation
+**Operator**: `-` (minus prefix)
+**Usage**: NOT equal to
+```
+-status:draft             # Not draft posts
+-featured:true            # Non-featured posts
+-tag:internal             # Posts not tagged "internal"
+```
+
+### 3. Comparison Operators
+**Operators**: `>`, `>=`, `<`, `<=`
+**Usage**: Numeric and date comparisons
+```
+published_at:>2023-01-01  # Posts published after date
+read_time:>5              # Posts with reading time > 5 minutes
+published_at:<=now-7d     # Posts published within last 7 days
+```
+
+### 4. Text Matching
+**Operators**: `~`, `~^`, `~$`
+**Usage**: Partial text matching
+```
+title:~ghost              # Title contains "ghost"
+slug:~^getting-started    # Slug starts with "getting-started"
+excerpt:~$tutorial        # Excerpt ends with "tutorial"
+```
+
+### 5. Group Selection
+**Operator**: `[value1, value2, ...]`
+**Usage**: Match any value in the list
+```
+tag:[news,updates,blog]   # Posts with any of these tags
+author:[john,jane,bob]    # Posts by any of these authors
+status:[published,draft]  # Published or draft posts
+```
+
+## Value Types
+
+### 1. Null Values
+```
+feature_image:null        # Posts without feature image
+custom_excerpt:-null      # Posts with custom excerpt (not null)
+```
+
+### 2. Boolean Values
+```
+featured:true
+featured:false
+page:true                 # Only pages
+page:false                # Only posts
+```
+
+### 3. Numbers
+```
+read_time:>10
+read_time:<=5
+comment_count:0
+```
+
+### 4. Literal Strings
+**Format**: No quotes needed for simple strings
+```
+status:published
+tag:javascript
+author:john-doe
+```
+
+### 5. Quoted Strings
+**Format**: Single quotes for strings with special characters
+```
+title:'My Post Title'
+tag:'getting started'
+excerpt:'This is a long excerpt with spaces'
+```
+
+### 6. Relative Dates
+**Format**: `now`, `now-Xd` (days), `now-Xm` (months), `now-Xy` (years)
+```
+published_at:>now-30d     # Last 30 days
+created_at:<=now-1y       # More than 1 year old
+updated_at:>now-7d        # Updated in last week
+```
+
+## Combination Logic
+
+### 1. AND Operator
+**Operator**: `+`
+**Usage**: All conditions must be true
+```
+status:published+featured:true
+tag:news+published_at:>now-7d
+author:john+status:published+featured:true
+```
+
+### 2. OR Operator
+**Operator**: `,` (comma)
+**Usage**: Any condition can be true
+```
+status:published,status:draft
+tag:news,tag:updates
+author:john,author:jane
+```
+
+### 3. Precedence Control
+**Operator**: `()` (parentheses)
+**Usage**: Group conditions and control evaluation order
+```
+(tag:news,tag:updates)+status:published
+author:john+(status:published,status:draft)
+```
+
+## Complex Filter Examples
+
+### 1. Recent Featured Posts by Specific Authors
+```
+authors.slug:[john,jane]+featured:true+published_at:>now-30d
+```
+
+### 2. Published Content with Specific Tags, Excluding Drafts
+```
+tag:[tutorial,guide]+status:published+-status:draft
+```
+
+### 3. Posts with Reading Time Between 5-15 Minutes
+```
+read_time:>=5+read_time:<=15+status:published
+```
+
+### 4. Recent Posts with Feature Images
+```
+published_at:>now-7d+feature_image:-null+status:published
+```
+
+### 5. Pages or Featured Posts by Multiple Authors
+```
+(page:true,featured:true)+authors.slug:[admin,editor,writer]
+```
+
+## Field-Specific Filters
+
+### Posts/Pages
+```
+id:5f7c1b4b0c7b4b001f7b4b1c
+slug:my-post-slug
+title:~'How to'
+html:~'tutorial'
+plaintext:~'javascript'
+feature_image:null
+featured:true
+page:false
+status:published
+visibility:public
+created_at:>now-30d
+published_at:<=2023-12-31
+updated_at:>now-7d
+```
+
+### Tags
+```
+id:tag_id
+name:'JavaScript'
+slug:javascript
+description:~'programming'
+visibility:public
+```
+
+### Authors
+```
+id:author_id
+name:'John Doe'
+slug:john-doe
+email:john@example.com
+```
+
+### Relationships (Dot Notation)
+```
+authors.slug:john-doe
+authors.name:'John Doe'
+tags.slug:javascript
+tags.name:'JavaScript'
+primary_author.slug:admin
+primary_tag.slug:featured
+```
+
+## URL Encoding
+
+### Required Encoding
+Filter strings must be URL encoded when used in URLs:
+```javascript
+const filter = "tag:javascript+published_at:>now-7d";
+const encoded = encodeURIComponent(filter);
+// Result: tag%3Ajavascript%2Bpublished_at%3A%3Enow-7d
+```
+
+### Common Encodings
+```
+:  → %3A
++  → %2B
+,  → %2C
+>  → %3E
+<  → %3C
+~  → %7E
+[  → %5B
+]  → %5D
+'  → %27
+```
+
+## Limitations & Constraints
+
+### 1. Property Naming
+- Properties must start with a letter
+- Use dot notation for relationships
+- Case-sensitive property names
+
+### 2. Value Constraints
+- No regex or advanced pattern matching
+- Limited to defined operators
+- String values with special chars need quotes
+
+### 3. Performance Considerations
+- Complex filters may impact query performance
+- Index-based fields filter faster
+- Limit filter complexity for optimal response times
+
+### 4. API Limitations
+- Some fields may not be filterable
+- Admin API may have different filter availability than Content API
+- Check specific endpoint documentation for filter support
+
+## Implementation for MCP Server

+
+## Phase Implementation Strategy
+
+### Phase 1: Basic Filters (Current)
+```javascript

+tag:news
+author:john-doe
+```
+
+### Phase 2: Advanced Filters (Future)
+```javascript
+// Complex filters with operators
+published_at:>now-30d+featured:true
+authors.slug:[john,jane]+tag:[news,updates]
+title:~'tutorial'+read_time:>=5
+```
+
+### Phase 3: Filter Builder (Future)
+- Programmatic filter construction
+- Validation and sanitization
+- Advanced query optimization
+
+## Testing Strategy
+
+### Unit Tests
+```javascript
+describe('Ghost Filter Syntax', () => {
+  test('simple equality filter', () => {
+    expect(buildFilter('status', 'published')).toBe('status:published');
+  });
+
+  test('complex AND filter', () => {
+    const filter = 'status:published+featured:true';
+    expect(parseFilter(filter)).toMatchObject({
+      conditions: [
+        { property: 'status', operator: ':', value: 'published' },
+        { property: 'featured', operator: ':', value: 'true' }
+      ]
+    });
+  });
+});
+```
+
+### Integration Tests
+```javascript
+test('filter with real API', async () => {
+  const response = await contentApi.request('/posts/', {
+    filter: 'status:published+featured:true',
+    limit: 5
+  });
+  expect(response.posts.every(post =>
+    post.status === 'published' && post.featured === true
+  )).toBe(true);
+});
+```
+

+```
+
+## Key Research Findings
+
+### 1. Authentication Patterns
+- **Content API**: Simple query parameter authentication (`?key=api_key`)
+- **Admin API**: JWT token authentication with 5-minute expiration
+- **Implementation**: Node.js with jsonwebtoken library
+
+### 2. Content Formats
+- **Primary**: Lexical (JSON-based structured content)
+- **Secondary**: HTML (for compatibility and input)
+- **Legacy**: Mobiledoc (backward compatibility only)
+
+### 3. API Response Patterns
+- **Consistent Structure**: `{ resource_type: [...], meta: { pagination: {...} } }`
+- **Error Format**: `{ errors: [{ message, context, type, ... }] }`
+- **Filtering**: NQL (Node Query Language) with comprehensive operators
+
+### 4. Error Handling Strategy
+- **5 Categories**: Network, Authentication, Ghost API, MCP Protocol, File Upload
+- **Comprehensive Logging**: Structured JSON with request IDs
+- **Retry Logic**: Exponential backoff for transient errors
+
+### 5. MCP Tool Architecture
+- **Total Tools**: 44+ tools covering complete Ghost REST API
+- **Content API**: 13 read-only tools
+- **Admin API**: 31+ read/write tools including advanced features

+# Ghost API Rate Limiting Documentation
+
+## Overview
+Documentation of Ghost API rate limiting behavior and best practices for the MCP server implementation.
+
+## Current Knowledge
+Based on initial research, Ghost APIs do not have strict documented rate limits, but reasonable usage is expected.
+
+## Content API Rate Limiting
+
+### Observed Behavior
+- No strict rate limits documented
+- Designed for public consumption
+- Responses are fully cacheable
+- No rate limit headers observed in initial testing
+
+### Best Practices
+- Implement caching for repeated requests
+- Use appropriate cache headers
+- Avoid excessive concurrent requests
+- Monitor response times
+
+## Admin API Rate Limiting
+
+### Observed Behavior
+- No strict rate limits documented
+- Server-side usage expected
+- JWT tokens expire after 5 minutes (natural rate limiting)
+
+### Best Practices
+- Reuse JWT tokens within validity period
+- Avoid generating new tokens for each request
+- Implement request queuing for bulk operations
+- Monitor API response times and errors
+
+## Implementation Recommendations
+
+### Caching Strategy
+```javascript
+// TODO: Phase 1 - Implement request caching
+class GhostApiCache {
+  constructor(ttl = 300000) { // 5 minutes default
+    this.cache = new Map();
+    this.ttl = ttl;
+  }
+
+  get(key) {
+    const item = this.cache.get(key);
+    if (item && Date.now() < item.expiry) {
+      return item.data;
+    }
+    this.cache.delete(key);
+    return null;
+  }
+
+  set(key, data) {
+    this.cache.set(key, {
+      data,
+      expiry: Date.now() + this.ttl
+    });
+  }
+}
+```
+
+### Rate Limiting Detection
+- Monitor for 429 status codes
+- Watch for response time degradation
+- Implement backoff on authentication errors
+
+### Connection Pooling
+- Use HTTP connection pooling
+- Limit concurrent requests
+- Queue requests during high load
+
+## Research Status
+- ⏳ Rate limit testing pending API keys
+- ⏳ Load testing pending implementation
+- ⏳ Cache strategy pending Phase 1
+- ⏳ Performance monitoring pending implementation
+
+## Future Research Areas
+1. Test actual rate limits with API keys
+2. Measure response times under load
+3. Test cache effectiveness
+4. Monitor for any undocumented limits
