GET /v1/connectors — MCP directory API referenceMatching Connector Tools:
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.
Testing, benchmarking and auditing autonomous AI agents — methods, harnesses, evidence
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.
Author and validate Calaf workspace seeds against the app's real importer. No account needed.
Risk-scan a diff, flag AI-generated-code tells, find secrets. 5 of 7 tools need no account.
Generate synthetic random user data for testing, demos, and development without using real persona.
Simulate, test, and analyze cloud architectures without deploying real infrastructure. Cloud World Model enables AI agents to model cloud environments, evaluate architecture behavior and costs, run failure and chaos simulations, and explore infrastructure scenarios across cloud providers.
Workflow planning, recovery checkpoints, coordination, fixtures, and compatibility tools for agents.
Moderated usability testing: read sessions, notes, transcripts, reports, and draft test scenarios.
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).
Prompt evals over MCP: run a prompt on your dataset, score each output 1-5 with an LLM judge.
Free platform to test MCP clients without installing anything. Create mock tools with dynamic templates, configurable delays, conditions (if/then), and response sequences. Supports JSON-RPC 2.0 over Streamable HTTP. Built-in text_echo and json_echo tools. Rate-limited tiers: anonymous (5 calls/min, 1 mock tool), registered (10 calls/min, 4 mock tools), premium (60 calls/min, unlimited). Zero setup — no install, no registration required.
