Problem
Teams either give agents no access (useless) or admin credentials (reckless).
Solution
Front each internal system with a scoped MCP server that enforces permissions server-side.
Steps
- 01Inventory systems and classify each operation: read, write, irreversible.
- 02Create one MCP server per system, not one god-server.
- 03Authenticate the end user, not the agent: forward the user's token and let RLS apply.
- 04Expose read tools first. Ship writes only after read usage is understood.
- 05Log every tool call with user, arguments and result size.
- 06Review the logs weekly and remove tools nobody calls — surface area is risk.
