UI Verify is visual regression testing built for coding agents. Connect the MCP server and your agent (Claude Code, Cursor, Codex) pulls a pull request's UI changes into the conversation, views each visual diff, reads the AI judge's verdict of regression vs intended change, and accepts the intended baselines - all over MCP.
Verify before your agent acts on data it paid for. Signed verdicts, checkable offline, via x402.
Generate synthetic random user data for testing, demos, and development without using real persona.
Moderated usability testing: read sessions, notes, transcripts, reports, and draft test scenarios.
Prompt evals over MCP: run a prompt on your dataset, score each output 1-5 with an LLM judge.
