Trust boundary

Data flow

Only flows that exist today are listed. Inspection and model-backed evaluation have deliberately different boundaries.

Local inspect

inspect connects from your machine to the MCP server you name, scores the schema, and can write report.md next to you. Nothing is uploaded off your machine.

Eval

Optional. Uses a model key you provide. Credential values stay on your machine; the task, tool schemas, calls, and results are sent to the selected provider. MCP Doctor does not store them.

Website

Pages are hosted on Vercel. Product analytics and install-copy tracking are disabled for this launch.

Not enabled

CLI telemetry ingestion
Stripe checkout
Accounts

Optional waitlist

With your explicit consent, the website sends your email to its Vercel API route and stores it in a connected Neon Postgres database. Duplicate addresses are treated as an existing signup. No MCP data is collected.
