MCP Tool Gateway
A protocol gateway that exposes a narrow, governed tool surface to multiple agent clients.
When to use it
- Several clients need the same capability.
- Tool ownership is separate from agent application ownership.
- Auth, audit, and rate limits belong at the tool boundary.
Avoid when
- One app owns the whole stack.
- The tool is unsafe without manual approval.
Implementation notes
- Start with read-only tools.
- Keep schemas narrow and typed.
- Record calls with actor, tenant, and tool arguments.
