[mooreds]

Support the Model Context Protocol in FusionAuth to allow for direct manipulation of FusionAuth configuration and direct interrogation of FusionAuth data by LLMs.

• https://huggingface.co/blog/mclenhard/mcp-evals

Possible implementations:

• Part of the FusionAuth executable
• Generated like the client libs as well

Possible tools for an MCP server:

• thin API wrapper, like the client libraries
• higher level use cases like
  • theme my login page like my current site
  • migrate from to FusionAuth
  • check my configuration to make sure it is OAuth 2.1 compliant
  • set up one FusionAuth for one of these use cases: https://fusionauth.io/docs/get-started/use-cases/
  • here's my list of APIs, permissions and relationships. set these up as entities

This has been partially completed by the preview API MCP server: https://fusionauth.io/docs/get-started/download-and-install/development/mcp-server

In this case, we implemented a "thin API wrapper, like the client libraries"
