AVR Docs MCP Server with Wiki.JS Integration

This MCP (Model Context Protocol) server provides integration with Wiki.JS for searching and listing pages from your Wiki.JS instance.

Features

• Search Wiki.JS Pages: Search for pages using keywords or topics
• List Wiki.JS Pages: Get a paginated list of all available pages
• Get Specific Page: Retrieve a specific page by its ID
• Connection Testing: Test the connection to your Wiki.JS instance
• Multiple Transport Modes: Support for both stdio and HTTP stream modes
• Docker Support: Ready-to-use Docker image with health checks

Setup

Prerequisites

1. A running Wiki.JS instance
2. An API key with appropriate permissions for reading pages

Environment Variables

You can set environment variables in two ways:

Option 1: Using a .env file (Recommended)

1. Copy the example environment file:

cp .env.example .env

2. Edit the .env file with your actual values:

# Wiki.JS Configuration
WIKI_JS_BASE_URL=https://your-wiki-instance.com
WIKI_JS_API_KEY=your-api-key-here
LOG_LEVEL=info

# MCP Server Configuration
MCP_MODE=stdio
PORT=3000

Option 2: Using system environment variables

export WIKI_JS_BASE_URL="https://your-wiki-instance.com"
export WIKI_JS_API_KEY="your-api-key-here"
export LOG_LEVEL="info"
export MCP_MODE="stdio"
export PORT="3000"

Installation

1. Install dependencies:

npm install

2. Build the project:

npm run build

3. Test the connection (optional):

npm test

4. Run the server:

npm start

For development:

npm run dev

Running Modes

The server supports two modes of operation:

Stdio Mode (Default)

The server runs in stdio mode by default, communicating through standard input/output. This is the traditional MCP mode.

npm start
# or
npm run start:http  # for HTTP mode
# or
MCP_MODE=stdio npm start

HTTP Stream Mode

The server can also run in HTTP mode, providing a REST API with Server-Sent Events (SSE) for MCP communication.

npm run start:http
# or
MCP_MODE=http npm start

When running in HTTP mode, the server provides:

• Health Check: GET /health - Returns server status
• MCP Endpoint: POST /mcp - MCP communication endpoint using JSON-RPC 2.0

Testing HTTP Mode

You can test the HTTP mode using curl or Postman:

# Health check
curl http://localhost:3000/health

# Initialize MCP session
curl -X POST http://localhost:3000/mcp \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "initialize",
    "params": {
      "protocolVersion": "2024-11-05",
      "capabilities": {},
      "clientInfo": {
        "name": "curl-client",
        "version": "1.0.0"
      }
    }
  }'

# List available tools (use session ID from initialize response)
curl -X POST http://localhost:3000/mcp \
  -H "Content-Type: application/json" \
  -H "mcp-session-id: <session-id-from-initialize>" \
  -d '{"jsonrpc": "2.0", "id": 2, "method": "tools/list"}'

# Call a tool (use session ID from initialize response)
curl -X POST http://localhost:3000/mcp \
  -H "Content-Type: application/json" \
  -H "mcp-session-id: <session-id-from-initialize>" \
  -d '{
    "jsonrpc": "2.0",
    "id": 3,
    "method": "tools/call",
    "params": {
      "name": "search_wiki_pages",
      "arguments": {
        "query": "deepgram",
        "page": 1,
        "limit": 10
      }
    }
  }'

Or use the built-in test client:

npm run test:http

Docker Usage

Available Tools

1. search_wiki_pages

Search for pages in Wiki.JS using keywords.

Parameters:

• query (required): The search query
• page (optional): Page number for pagination (default: 1)
• limit (optional): Number of results per page (default: 10, max: 50)

2. list_wiki_pages

List all available pages in Wiki.JS.

Parameters:

• page (optional): Page number for pagination (default: 1)
• limit (optional): Number of results per page (default: 20, max: 50)

3. get_wiki_page

Get a specific page by its ID or path.

Parameters:

• pageId (required): The ID (numeric) or path (string) of the page to retrieve. Examples: '3' for ID, 'deepgram' for path

Wiki.JS API Configuration

This MCP server uses Wiki.JS GraphQL API (/graphql endpoint). Make sure your Wiki.JS instance has API access enabled and that your API key has the following permissions:

• page:read - To read page content
• page:list - To list pages
• search:read - To search pages

The server automatically handles GraphQL queries and responses for all operations. Note that Wiki.JS GraphQL API has some limitations:

• Search and list operations don't support native pagination, so pagination is simulated client-side
• Search results don't include full page content
• List results don't include full page content (use get_wiki_page for full content)
• Tags are returned as arrays of strings, not comma-separated strings

Logging

The server includes comprehensive logging with configurable log levels:

• debug - Detailed debug information
• info - General information (default)
• warn - Warning messages only
• error - Error messages only

Set the LOG_LEVEL environment variable to control logging verbosity.

Error Handling

The server includes comprehensive error handling for:

• Missing environment variables
• Network connectivity issues
• API authentication failures
• Invalid page IDs
• Rate limiting

Development

To run in development mode with hot reloading:

npm run watch

Building

To build for production:

npm run build

The compiled JavaScript will be in the dist/ directory.
