Risk-scan a diff, flag AI-generated-code tells, find secrets. 5 of 7 tools need no account.
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.
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.
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).
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.

Probe a signup URL you own and score whether an AI agent can sign up unaided.
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.
Scores any public website on how usable it is by AI agents, with per-check evidence.
Resolve whether an uncertain side-effecting action completed before software retries it.
Check what a paid x402 endpoint or MCP server delivered, from probes anyone can repeat.
Ensemble testing of web pages for accessibility, usability, and standards conformity
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.
Deterministic operations reconciliation for AI agents: COMPLETE, INCOMPLETE, or NEEDS_REVIEW.
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.
Verify an agent's advertised route, price, payment details, and schemas against its live endpoint.
