Multi-service MCP Server

# Model Context Protocol (MCP) Server A modular server that implements the [Model Context Protocol](https://modelcontextprotocol.io/) standard, providing tools for GitHub, GitLab, Google Maps, Memory storage, and Puppeteer web automation. ## Architecture The MCP server is built with a modular architecture, where each tool is implemented as a separate module. The server provides a unified gateway that routes requests to the appropriate tool.  ## Features - **MCP Gateway**: A unified endpoint for all tool requests following the MCP standard - **MCP Manifest**: An endpoint that describes all available tools and their capabilities - **Direct Tool Access**: Each tool can be accessed directly via its own API endpoints - **Modular Design**: Easy to add or remove tools as needed ### Included Tools 1. **GitHub Tool**: Interact with GitHub repositories, issues, and search 2. **GitLab Tool**: Interact with GitLab projects, issues, and pipelines 3. **Google Maps Tool**: Geocoding, directions, and places search 4. **Memory Tool**: Store and retrieve data persistently 5. **Puppeteer Tool**: Take screenshots, generate PDFs, and extract content from websites ## Getting Started ### Prerequisites - Python 3.8 or higher - Node.js 14 or higher - A Red Hat-based Linux distribution (RHEL, CentOS, Fedora) or any Linux/macOS system ### Installation 1. Clone this repository: ```bash git clone https://github.com/yourusername/mcp-server.git cd mcp-server ``` 2. Install Python dependencies: ```bash pip install -r requirements.txt ``` 3. Install Node.js dependencies: ```bash npm install ``` 4. Create a `.env` file with your configuration: ``` SECRET_KEY=your-secret-key DEBUG=False # GitHub configuration GITHUB_TOKEN=your-github-token # GitLab configuration GITLAB_TOKEN=your-gitlab-token # Google Maps configuration GMAPS_API_KEY=your-google-maps-api-key # Memory configuration MEMORY_DB_URI=sqlite:///memory.db # Puppeteer configuration PUPPETEER_HEADLESS=true CHROME_PATH=/usr/bin/chromium-browser ``` 5. Start the server: ```bash python app.py ``` ### Containerized Deployment You can run the server using either Docker or Podman (Red Hat's container engine). #### Docker Deployment If you already have Docker and docker-compose installed: 1. Build the Docker image: ```bash docker build -t mcp-server . ``` 2. Run the container: ```bash docker run -p 5000:5000 --env-file .env mcp-server ``` 3. Alternatively, use docker-compose: Create a `docker-compose.yml` file: ```yaml version: '3' services: mcp-server: build: . ports: - "5000:5000" volumes: - ./data:/app/data env_file: - .env restart: unless-stopped ``` Then run: ```bash docker-compose up -d ``` #### Podman Deployment For Red Hat based systems (RHEL, CentOS, Fedora) using Podman: 1. Build the container image: ```bash podman build -t mcp-server . ``` 2. Run the container: ```bash podman run -p 5000:5000 --env-file .env mcp-server ``` 3. If you need persistent storage: ```bash mkdir -p ./data podman run -p 5000:5000 --env-file .env -v ./data:/app/data:Z mcp-server ``` Note: The `:Z` suffix is important for SELinux-enabled systems. 4. Using Podman Compose (if installed): ```bash # Install podman-compose if needed pip install podman-compose # Use the same docker-compose.yml file as above podman-compose up -d ``` ## Using the MCP Server ### MCP Gateway The MCP Gateway is the main endpoint for accessing all tools using the MCP standard. **Endpoint**: `POST /mcp/gateway` **Request format**: ```json { "tool": "github", "action": "listRepos", "parameters": { "username": "octocat" } } ``` **Response format**: ```json { "tool": "github", "action": "listRepos", "status": "success", "result": [ { "id": 1296269, "name": "Hello-World", "full_name": "octocat/Hello-World", "owner": { "login": "octocat", "id": 1 }, ... } ] } ``` ### MCP Manifest The MCP Manifest describes all available tools and their capabilities. **Endpoint**: `GET /mcp/manifest` **Response format**: ```json { "manifestVersion": "1.0", "tools": { "github": { "actions": { "listRepos": { "description": "List repositories for a user or organization", "parameters": { "username": { "type": "string", "description": "GitHub username or organization name" } }, "returns": { "type": "array", "description": "List of repository objects" } }, ... } }, ... } } ``` ### Direct Tool Access Each tool can also be accessed directly via its own API endpoints: - GitHub: `/tool/github/...` - GitLab: `/tool/gitlab/...` - Google Maps: `/tool/gmaps/...` - Memory: `/tool/memory/...` - Puppeteer: `/tool/puppeteer/...` See the API documentation for each tool for details on the available endpoints. ## Tool Documentation ### GitHub Tool The GitHub tool provides access to the GitHub API for repositories, issues, and search. **Actions**: - `listRepos`: List repositories for a user or organization - `getRepo`: Get details for a specific repository - `searchRepos`: Search for repositories - `getIssues`: Get issues for a repository - `createIssue`: Create a new issue in a repository ### GitLab Tool The GitLab tool provides access to the GitLab API for projects, issues, and pipelines. **Actions**: - `listProjects`: List all projects accessible by the authenticated user - `getProject`: Get details for a specific project - `searchProjects`: Search for projects on GitLab - `getIssues`: Get issues for a project - `createIssue`: Create a new issue in a project - `getPipelines`: Get pipelines for a project ### Google Maps Tool The Google Maps tool provides access to the Google Maps API for geocoding, directions, and places search. **Actions**: - `geocode`: Convert an address to geographic coordinates - `reverseGeocode`: Convert geographic coordinates to an address - `getDirections`: Get directions between two locations - `searchPlaces`: Search for places using the Google Places API - `getPlaceDetails`: Get details for a specific place ### Memory Tool The Memory tool provides a persistent key-value store for storing and retrieving data. **Actions**: - `get`: Get a memory item by key - `set`: Create or update a memory item - `delete`: Delete a memory item by key - `list`: List all memory items, with optional filtering - `search`: Search memory items by value ### Puppeteer Tool The Puppeteer tool provides web automation capabilities for taking screenshots, generating PDFs, and extracting content from websites. **Actions**: - `screenshot`: Take a screenshot of a webpage - `pdf`: Generate a PDF of a webpage - `extract`: Extract content from a webpage ## Contributing Contributions are welcome! Here's how you can extend the MCP server: ### Adding a New Tool 1. Create a new file in the `tools` directory, e.g., `tools/newtool_tool.py` 2. Implement the tool with actions following the same pattern as existing tools 3. Add the tool to the manifest in `app.py` 4. Register the tool's blueprint in `tools/__init__.py` ## License This project is licensed under the MIT License - see the LICENSE file for details. ## Acknowledgements - [Model Context Protocol](https://modelcontextprotocol.io/) for the standard specification - [Flask](https://flask.palletsprojects.com/) for the web framework - [Puppeteer](https://pptr.dev/) for web automation
