[MarcSkovMadsen]

This PR attempts to make it easier to use Panel Material UI with LLMs by providing a MCP server.

For details see Panel Material UI mcp.

Todo

• POC - provide component and reference documentation endpoints.
• Convert tools that return static content like best practices or similar to resources or prompts
• Improve document search. Should probably be based on vector store and similarity search.
• Figure out how this should be distributed.
  • When the mcp server starts the data used is collected into large Pydantic model which can be serialized and saved for reuse. I.e. the github actions could generate and save the .json files and a public or local mcp server could use them.
  • An alternative would be to support llms.txt output as described in Make HoloViz documentation useful for llms and holoviz mcp servers holoviz-dev/nbsite#341.
• Use and refine for a period of time.
• Refactor to make distributable
• Implement similar mcp server for Panel repository.
