MCP Catalog

Background

The mcp/docker container is an mcp server that can be extended with new container-based tools, and prompts. Existing containers, like curl or ffmpeg, can now be exposed as MCP servers without having to wrap each tool in an mcp server.

Definitions of new tools and prompts are made using markdown documents that can either use plain Docker image as tools, or serve requests to containerized MCP servers.

Getting Started

1. using Gordon
2. using Claude Desktop
3. using Cursor
4. testing definitions in vscode using our VSCode extension. Using VSCode as an mcp server can provide an effective inner loop for developing the content.
