MongoDB Model Context Protocol Server

A powerful server implementation for managing models, contexts, and protocols with MongoDB integration and Cursor support.

Features

- Model management (create, list, update, delete)
- Context management with multiple model support
- Protocol execution and status tracking
- Data storage and retrieval
- Cursor integration for enhanced code completion and analysis
- gRPC API for all operations
- MongoDB backend for persistent storage

Requirements

- Go 1.16 or higher
- MongoDB 4.4 or higher
- Cursor IDE (for full integration features)

Installation

1. Clone the repository:

git clone https://github.com/yourusername/mongo-mcp-server.git

cd mongo-mcp-server

2. Install dependencies:

go mod download

3. Start MongoDB:

mongod --dbpath /path/to/data/directory

4. Build and run the server:

go build -o mcp-server cmd/server/main.go

./mcp-server

Cursor Integration

The server includes built-in support for Cursor IDE integration. To enable Cursor features:

1. Install the Cursor IDE from cursor.sh
2. The server will automatically detect and integrate with Cursor when it's running
3. Use the /mcp prefix in Cursor to access MCP features:
- /mcp model - Manage models
- /mcp context - Manage contexts
- /mcp execute - Execute protocols
- /mcp status - Check protocol status
- /mcp data - Manage data

API Usage

Models

Create a new model:

grpcurl -plaintext -d '{

  "name": "gpt-4",

  "type": "llm",

  "description": "OpenAI GPT-4 model",

  "parameters": {

    "temperature": 0.7,

    "max_tokens": 2048

  }

}' localhost:50051 proto.MCPService/CreateModel

Contexts

Create a new context:

grpcurl -plaintext -d '{

  "name": "code-review",

  "description": "Code review context",

  "model_ids": ["model_id_1", "model_id_2"],

  "metadata": {

    "language": "go",

    "framework": "grpc"

  }

}' localhost:50051 proto.MCPService/CreateContext

Protocols

Execute a protocol:

grpcurl -plaintext -d '{

  "protocol_id": "protocol_id_1",

  "context_id": "context_id_1",

  "parameters": {

    "input": "Review this code",

    "style": "detailed"

  }

}' localhost:50051 proto.MCPService/ExecuteProtocol

Check protocol status:

grpcurl -plaintext -d '{

  "execution_id": "execution_id_1"

}' localhost:50051 proto.MCPService/GetProtocolStatus

Data

Add data:

grpcurl -plaintext -d '{

  "type": "code",

  "content": "package main\n\nfunc main() {\n    println(\"Hello, World!\")\n}",

  "metadata": {

    "language": "go",

    "author": "John Doe"

  }

}' localhost:50051 proto.MCPService/AddData

Get data:

grpcurl -plaintext -d '{

  "id": "data_id_1"

}' localhost:50051 proto.MCPService/GetData

List data:

grpcurl -plaintext -d '{

  "type": "code",

  "page_size": 10,

  "page_token": ""

}' localhost:50051 proto.MCPService/ListData

Delete data:

grpcurl -plaintext -d '{

  "id": "data_id_1"

}' localhost:50051 proto.MCPService/DeleteData

Security

- All API endpoints require authentication
- MongoDB connection uses secure defaults
- gRPC communication is encrypted
- Cursor integration uses secure channels
