This is a lightweight implementation of the MCP (Model Context Protocol) server. It's designed to be simple yet functional, allowing you to interact with AI models through a standardized protocol.
You can install the MCP server directly from GitHub:
pip install git+https://github.com/username/mcp-server.git
Or clone the repository and install manually:
git clone https://github.com/username/mcp-server.git
cd mcp-server
pip install -e .
To start the MCP server, use the following command:
python -m mcp_server
By default, the server listens on port 8000. You can specify a different port using the --port
option:
python -m mcp_server --port 9000
You can connect to the server using any MCP client. For a quick test, you can use curl:
curl -X POST http://localhost:8000/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{
"messages": [{"role": "user", "content": "Hello, world!"}],
"model": "default"
}'
The server can be configured by creating a configuration file or through environment variables. The basic configuration includes:
The server implements the standard MCP endpoints:
/v1/chat/completions
- For chat completions/v1/completions
- For text completions/v1/models
- To list available modelsYou can monitor the server's status and activity through logs, which are output to the console by default.
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.
To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".
When you click that button the ~/.cursor/mcp.json
file will be opened and you can add your server like this:
{
"mcpServers": {
"cursor-rules-mcp": {
"command": "npx",
"args": [
"-y",
"cursor-rules-mcp"
]
}
}
}
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.
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 explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
