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.
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.
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.
Synthetic checks, nightly regression replay and model-drift alerts for AI agents
Checks whether generated Minecraft Bedrock content will actually load. Nine read-only tools.
Ensemble testing of web pages for accessibility, usability, and standards conformity
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.
MCP tool observatory: do registry servers answer, and are their answers true? No key.
Runs your code against a contract; returns HELD or BROKE at the exact input. Deterministic.
Grade MCP servers A to F with the open behavioral litmus. npm: full toolset; hosted: lookups only.
Find MCP servers and check whether they actually respond, via live handshake probes.
Machine-readable taxonomy of 100+ AI system failure modes spanning factuality, alignment, planning, code generation, and instruction following.
MCP server for the Fail Modes taxonomy — a knowledge base of AI system failure modes
A flock of AI users tests your deployed app and reports where real people get stuck, with fixes.
