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

1. Install dependencies:

go mod download

1. Start MongoDB:

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

1. 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
