Diagnose why an AI agent failed and get the verified fix instantly. Free, no token.
Evidence-gated task verification for AI agents. Decompose goals into acceptance criteria, attach proof (screenshot, curl, file), independent LLM judge accepts or rejects. 24 tools. Hosted remote MCP (streamable-http, OAuth 2.1 + DCR).
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.
Risk-scan a diff, flag AI-generated-code tells, find secrets. 5 of 7 tools need no account.
What is known to be broken in an MCP server or API operation, with the check that found it.
Prompt evals over MCP: run a prompt on your dataset, score each output 1-5 with an LLM judge.
Test an email before it goes out: a disposable address, 41 checks with RFC citations, a fix plan.
