Containerd

This is an MCP server implemented using the RMCP (Rust Model Context Protocol) library for operating Containerd.

Features

• Implements an MCP server using the RMCP library
• Supports all Containerd CRI interface operations
• Provides Runtime Service interfaces
• Provides Image Service interfaces
• Supports ctr interface

Prerequisites

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

Building

cargo build --release

Running

mcp-containerd -t http  #use streamhttp
mcp-containerd --help #list the help info

By default, the service will connect to the unix:///run/containerd/containerd.sock endpoint.

Using with simple-chat-client

The simple-chat-client allows you to interact with the MCP Containerd service: simple-chat-client has moved to simple-chat-client

Example interaction:

> 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":[...]}

• version service: Provides CRI version information
• runtime service: Provides container and Pod runtime operations
• image service: Provides container image operations
