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).
MCP server for visual regression testing: triage a PR's UI diffs from your coding agent.
Check that your AI is being logical. Free tool that mathematically catches contradictions in agent reasoning. No account needed. Also offers paid guardrails that converts natural language to formal verification proofs, that anyone can check succinctly.
