GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
Risk-scan a diff, flag AI-generated-code tells, find secrets. 5 of 7 tools need no account.
Parse WebVTT, SRT, or TTML for conformance, timing, overlaps, line length, and reading speed.
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.
Load testing and synthetic monitoring platform: test with Playwright, Browser Bot, or Protocol Bots.
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).
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.

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.
Test a Python package/version on a target runtime. Scoped Linux install and usable-import evidence.
Rule engine with built-in simulation. 55 MCP tools for complete business rule lifecycle management.
X-Z-CS AI validation with auditable reasoning. 8 active tools; 5 in maintenance. v0.5.62
Check what a paid x402 endpoint or MCP server delivered, from probes anyone can repeat.
Agentic code review, no signup to try: reality gates + frontier-model review, with veto.
Tests an AI agent's purchase against the task it was given. Paid per call in USDC via x402.
Point Claude Code, Qwen Code, Cursor, or any MCP client at https://docs.jmeter.ai/api/mcp and your agent answers JMeter questions grounded in this documentation, with a source link for every answer. Free, no API key, no signup.
Give AI coding agents access to your Vynix visual feedback, bug reports, and AI diagnosis.
Scan any website or MCP server for agent readiness: 0-100 score, a fix per failing check. Free.
Accessibility pre-checks (WCAG/BFSG) in a real browser + statement drafts. Pay per call.
Runs your code against a contract; returns HELD or BROKE at the exact input. Deterministic.
Security + bug + perf + refactor audit for Python. Returns 0-10 score + MD report.
Machine-readable taxonomy of 100+ AI system failure modes spanning factuality, alignment, planning, code generation, and instruction following.
