Containerd MCP server

This MCP server implements a Model Context Protocol server for Containerd's Container Runtime Interface (CRI) using the RMCP (Rust Model Context Protocol) library. It provides programmatic access to container and image operations through a standardized interface.

Prerequisites

• Rust development environment
• Containerd installed and running
• Protobuf compilation tools

Installation

Build the MCP Containerd server with Cargo:

cargo build --release

Running the Server

Start the MCP server with:

cargo run --release

By default, the server connects to the Containerd socket at unix:///run/containerd/containerd.sock.

Using the Server

Interacting with simple-chat-client

You can use the simple-chat-client to interact with the MCP Containerd service, which is available in the rust-sdk repository.

Example interactions:

> please give me a list of containers
AI: Listing containers...
Tool: list_containers
Result: {"containers":[...]}

> please give me a list of images
AI: Here are the images in your containerd:
Tool: list_images
Result: {"images":[...]}

Available Services

Runtime Service

The runtime service provides interfaces for:

• Managing Pod sandboxes (Create/Stop/Delete)
• Container lifecycle operations (Create/Start/Stop/Delete)
• Querying Pod and container status
• Executing commands in containers

Image Service

The image service provides interfaces for:

• Listing available images
• Getting image status information
• Pulling new images
• Deleting images
• Retrieving image filesystem information

Version Service

Provides CRI version information to clients.

How to add this MCP server to 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 > 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"
            ]
        }
    }
}

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 explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
