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.
Conformance checker for MCP servers. Free, no key, verdicts recomputable and re-measured daily.
Verify before your agent acts on data it paid for. Signed verdicts, checkable offline, via x402.
Accessibility and WCAG data for your own websites: fix lists, live checks, and fix validation.
Lint a SKILL.md for frontmatter, structure, secrets and size. All 6 tools free.
Generate synthetic random user data for testing, demos, and development without using real persona.
Workflow planning, recovery checkpoints, coordination, fixtures, and compatibility tools for agents.
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).

Scan GitHub-hosted AI skills for vulnerabilities: prompt injection, malware, OWASP LLM Top 10.
Webhook capture bins for agents: get a URL, wait for webhooks, set replies, verify signatures.
Hire a real human for real-world verification, product testing, AI output review, and errands.
