Will an AI pick your tools?
When someone asks Claude, ChatGPT or Cursor to get a job done, the model chooses from the tools it has. If it picks a competitor's, you never hear about it. This test measures how often real models choose your MCP server over the services you compete with, shows you why they passed, rewrites your tool descriptions and measures again.
Test my server How it worksYour tools, next to your rivals', in front of real models.
- You give us your MCP URL. We read your public tool list. We never call your tools and never need a login.
- We find who you compete with. Same-category servers from the official MCP Registry, put in the same tool list as yours.
- Real models choose. Three model families get 20 plain-language requests your server is built for, five times each, with the tool order shuffled every time.
- You get the result. Your pick rate with its 95% range, overall and per model; which rivals won instead; what the models said was missing or unclear in your descriptions.
- We rewrite and retest. New tool descriptions, truthful to what your tools do, measured on half the requests that the rewrite never saw. You see the before and after, and you can paste the new descriptions straight in.
Measured, not scored
No checklist out of 100. A count of how often models chose you, with the sample size and uncertainty shown.
Read-only
Only your public tools/list is read. No tool on your server or anyone else's is invoked.
No tricks
Rewrites never tell a model to prefer you or mention competitors. They describe your tools better.
Honest limits
This tests choice among connected tools. It can't see installs, client ranking or your real traffic, and the report says so.
