DARP Engine MCP server

DARPEngine is a search engine designed specifically for Model Context Protocol (MCP) servers. It stores metadata for MCP servers hosted online and provides smart search capabilities, allowing you to find and connect to the most relevant MCP server for your specific questions or tasks.

Installation

To install DARPEngine, follow these steps:

export OPENAI_API_KEY=sk-...
docker network create highkey_network
docker compose build
docker compose -f docker-compose.yaml -f docker-compose-debug.yaml up --build --wait

Usage

Connecting to an MCP Client

You can connect DARPEngine to an MCP Client (such as Claude Desktop or Cursor) using the provided MCP tools:

1. In your MCP client, select SSE mode
2. Specify http://localhost:4689/sse as the endpoint

Using the CLI

Alternatively, you can use DARPEngine via the command line interface. While most scripts work with standard Python libraries, the routing tool requires the MCP package.

Setting up the CLI environment

conda create -n darp 'python>=3.10'
conda activate darp
pip install -r mcp_server/requirements.txt

Adding MCP Servers

To add MCP servers to the engine:

python scripts/darp-add.py --url http://memelabs.ai:3006/sse --name code_analysis --description "Analyze gitlab repo for quality, topics, packages use"

Searching for Servers

To search for servers that can handle a specific request:

python scripts/darp-search.py "Analyze https://github.com/BenderV/autochat"

This will return a list of servers that can handle your request:

Found 1 servers:
code_analysis

Using the Routing Tool

For more comprehensive results, you can use the routing tool:

python scripts/darp-router.py "Analyze https://github.com/BenderV/autochat"

This will use the appropriate MCP servers to process your request and return detailed results. The effectiveness of this tool depends on the MCP servers you've connected to the engine.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "darp-engine" '{"url":"http://localhost:4689/sse"}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "darp-engine": {
            "url": "http://localhost:4689/sse"
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "darp-engine": {
            "url": "http://localhost:4689/sse"
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
