One suite. Every major MCP client.
Define test scenarios once, run them against ChatGPT, Claude, Cursor, and more in parallel. Ship with confidence that your server behaves the same everywhere.
Our open source tools are used by developers at top companies
Client matrices without the chaos
MCP clients behave differently. Tool parsing, auth flows, and capability negotiation all vary. Eval suites let you pin expected behavior and catch regressions before your users do.
Fix once, test everywhere
Failed runs link to the exact request payload and client log. Fix and re-run. Gate merges on green.
Reproducible runs
Versioned test packs and shared fixtures so your team agrees on what passing looks like.
Deep inspection
Pair runs with traces and payloads so failures are obvious, not guessed at from log excerpts.
Pre-release gates
Block merges or publishes when a required client profile regresses.
Ready to run your suite across every client?
Deploy your MCP on Manufact Cloud, wire ChatGPT, Claude, Cursor, and other profiles once, then run the same evals everywhere, or hook CI so a regression on any client blocks the merge.
