Bucketeer Docs Local MCP Server

Overview

This project provides a Model Context Protocol (MCP) server for Bucketeer documentation. It offers an interface for searching and retrieving content from Bucketeer's feature flag and experimentation platform documentation, enabling AI assistants to provide accurate information about Bucketeer's features and usage.

Starting the Server

npm start

Document Sources

The server automatically fetches and indexes documentation from the bucketeer-io/bucketeer-docs repository:

• GitHub Repository Integration:

  • Automatically fetches .mdx files from the docs/ directory and all subdirectories
  • Processes frontmatter and markdown content for optimal search indexing
  • Caches fetched content using SHA hashes and only updates when files are modified
  • Supports recursive directory traversal to capture all documentation files

• Intelligent Indexing:

  • Extracts keywords from titles, descriptions, headers, and content
  • Builds searchable index with relevance scoring based on keyword matches and full-text search
  • Optimized for Bucketeer-specific terminology (feature flags, experiments, SDKs, targeting, etc.)
  • Handles frontmatter extraction (title, description) from MDX files

• Cache Management:

  • Files are cached locally in files/docs/ directory as JSON files
  • Document index is stored in files/index/document-index.json
  • GitHub cache stored in files/docs/github_cache.json with SHA-based change detection
  • Use npm run build:index:force to force rebuild the entire index

Using with npx

First-time Setup

1. Build the document index:

npx @bucketeer/docs-local-mcp-server build-index

2. Use in your MCP configuration as shown in the next section.

Updating the Index

To update the documentation index (e.g., when new documentation is available):

npx @bucketeer/docs-local-mcp-server build-index --force

Development Commands

• npm run build - Compile TypeScript files to dist/ directory
• npm run build:index - Build/update the document index from GitHub repository
• npm run build:index:force - Force rebuild the entire index (ignores cache)
• npx @bucketeer/docs-local-mcp-server build-index - Build index using npx
• npx @bucketeer/docs-local-mcp-server build-index --force - Force rebuild index using npx
• npm run dev:index - Build and update index in development mode
• npm run dev - Build and start server in development mode
• npm run lint - Run Biome linting
• npm run lint:fix - Run Biome linting and fix linting errors

File Structure

Architecture

The server consists of several key components:

1. GithubDocumentFetcher: Recursively fetches .mdx files from the GitHub repository
2. IndexManager: Builds and manages the searchable document index
3. SearchService: Provides search functionality with keyword matching and full-text search
4. MCP Server: Exposes tools via the Model Context Protocol

Environment Setup

Requirements

• Node.js 18+
• npm

Installation Steps

1. Clone the repository:

git clone <repository-url>
cd bucketeer-docs-local-mcp-server

2. Install dependencies:

npm install

3. Build the project:

npm run build

4. Build the document index:

npm run build:index

Cursor and Claude Desktop Configuration

Configure the MCP Server by adding the following to your mcp.json or claude_desktop_config.json file, referring to the documentation for Cursor (https://docs.cursor.com/context/model-context-protocol#configuring-mcp-servers) and Claude Desktop (https://modelcontextprotocol.io/quickstart/user):

Quick Install with Cursor Deeplink

For Cursor users, you can install the MCP server with a single click using the deeplink below:

This will automatically configure the MCP server in your Cursor settings. After clicking the link, Cursor will prompt you to install the server.

Option 1: Using npx (Recommended)

{
  "mcpServers": {
    "bucketeer-docs": {
      "type": "stdio",
      "command": "npx",
      "args": ["@bucketeer/docs-local-mcp-server"]
    }
  }
}

Option 2: Using local installation

{
  "mcpServers": {
    "bucketeer-docs": {
      "type": "stdio",
      "command": "npm",
      "args": ["start", "--prefix", "/path/to/bucketeer-docs-local-mcp-server"]
    }
  }
}

Usage

When the MCP server is running, the following tools are available:

1. search_docs - Search Bucketeer Documentation

• Parameter: query (string) - The search query
• Parameter: limit (number, optional) - Maximum number of results to return (default: 5)

Example:

{
  "name": "search_docs",
  "arguments": {
    "query": "feature flags SDK integration",
    "limit": 5
  }
}

Response: Returns an array of search results with title, URL, path, description, excerpt, and relevance score.

2. get_document - Get Specific Document Content

• Parameter: path (string) - Document path obtained from search results

Example:

{
  "name": "get_document",
  "arguments": {
    "path": "getting-started/create-feature-flag"
  }
}

Response: Returns the full document content including title, description, URL, and complete markdown content.

Configuration

The server is configured via src/config/index.ts:

• siteName: "Bucketeer"
• websiteUrl: "https://docs.bucketeer.io"
• githubRepo: "https://github.com/bucketeer-io/bucketeer-docs"
• docsDirectory: "docs" (directory in GitHub repo containing documentation)
• searchLimitDefault: 5 (default number of search results)
• useGithubSource: true (always uses GitHub as source)
