Has anyone integrated Model Context Protocol (MCP) into their product?

Hey PH community 👋

I’m exploring the integration of Model Context Protocol (MCP) the vendor-neutral standard for passing app-specific context into LLMs and I’m curious if anyone here has already worked with it.

If you’ve done it:

• What kind of app or use case did you apply it to?

• Which model/provider were you using it with?

• What kind of context did you pass (user data, document state, actions, etc.)?

• Any challenges or unexpected wins?

• Would you recommend MCP as a stable integration layer?

Would love to learn from real-world examples before diving deeper.

Thanks! 🙌
