Limits

Free tier is generous enough for prototyping. Heavy use → paid tier waitlist.

Questions

Is the data real?
No. Every tool returns generated fake data, seeded from your inputs. Nothing persists. Perfect for prototyping, tutorials, or evals.
Do I need an account?
No. No signup, no API key, no config. Paste the URL, run your agent.
Why would I use this instead of a real API?
Because your agent isn't finished and neither is your backend. MockMCP lets you design and test agent logic before the real plumbing exists.
What about rate limits in CI?
If you're running evals against MockMCP at scale, hit the waitlist. A paid tier with reliability guarantees is coming for exactly that use case.
Can I see the source?
Yes — open source at github.com/k-cupples/mockmcp.
