Overview
What is crossplane-mcp-server?
crossplane-mcp-server is a Python server that implements the Model Context Protocol (MCP) for Crossplane. It allows an LLM to talk to Kubernetes and query Crossplane-related resources such as CompositeResourceDefinition (XRD), Composition, and ManagedResource (MR).
How to use crossplane-mcp-server?
Configure it as an MCP server in VS Code by adding the provided JSON block to mcp.json, or in Claude Desktop by adding it to claude_desktop_config.json. In both cases the server is started with uv running src/server.py.
Key features of crossplane-mcp-server
- List Compositions
- Get a specific Composition
- List CompositeResourceDefinitions
