Problem
Every AI client needs its own integration, so your app is reachable from none of them.
Solution
Publish one MCP server with a small, well-described tool surface and let clients discover it.
Steps
- 01List the 5–8 jobs an AI assistant should do in your app. Ignore everything else.
- 02Split them into tools (actions) and resources (readable context).
- 03Write typed input schemas — narrow fields, no free-form SQL or shell.
- 04Annotate each tool: read-only, destructive, idempotent. Gate destructive ones.
- 05Return compact structured output; never dump raw payloads back into context.
- 06Choose transport: stdio for local dev tooling, streamable HTTP + OAuth for remote.
- 07Test with a real client (Claude, Cursor) and iterate on the tool descriptions.
