Functionize MCP

Build, run and diagnose tests against your real app from Claude Code, Cursor or Copilot.
The Functionize MCP server connects your coding agent to Functionize Studio. Ask for a test in plain language and the result comes back in the chat.

Works with

Quality you Control

Ask for a test suite in the chat you already have open

You know the product, decide what counts, and judge what's ready. That's the work that matters. Studio sees how your application behaves and tests against it at scale, with your judgment setting the standard.

You Define Quality

  • What evidence is enough to ship
  • Which risks actually matter
  • Whether a flagged change is acceptable
  • Which bugs are worth fixing first
  • What to test next

Studio Executes

  • Writing tests from plain language
  • Running across browsers & environments in parallel
  • Re-identifying elements when the UI moves
  • Diagnosing failures, separating real bugs from noise
  • Turning every run into a clear release signal
Every Task Handled

While the code keeps coming, Studio keeps testing

You're being asked to verify more than any team can keep up with, and it grows every release.
Studio scales with you, so you finally keep pace.

Studio keeps pace
Test Breakage
The UI changes. You spend two days tracking down which tests broke and why.

​

Self-Healing

Studio re-identifies and heals the affected tests mid-run. You see a report, not a backlog.

New coverage
A new feature ships. Writing coverage for it means pausing everything else.

Simply prompt

Describe the feature in plain language. Studio builds the tests, maps the data, and adds them to the suite.
False Positives
The UI changes. You spend two days tracking down which tests broke and why.

RCA

Studio diagnoses the failure, tells you if it is a real regression, and fixes what it can. You decide what happens next.
Stacked interface layers representing test coverage that stays current across software releases
Coverage Drift
Coverage drifts between releases. You do not find out until something breaks in production.

You Unlock
​

Coverage you can see

Coverage maps update with every run, so every release has a clear go/no-go signal behind it, not a guess.

FAQ

Claude Code, Claude Desktop, Cursor and GitHub Copilot in VS Code, plus any client that supports MCP.

Both. Ask for a full smoke or regression suite, or let your agent pass a change and Studio runs the affected flows.

The server has no access to your file system. It works from what your coding agent sends it and from your running app.

No. It builds, runs and diagnoses tests. The release call stays with your team.
