Conformance checker for MCP servers. Free, no key, verdicts recomputable and re-measured daily.
Parse WebVTT, SRT, or TTML for conformance, timing, overlaps, line length, and reading speed.
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.
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).
Drive real Android & iOS devices and web browsers from natural language for mobile + web QA. 290+ tools across device control, app management, automation sessions, browser automation, and flow recording / replay. Bearer-auth — get a token at robotactions.com → Profile → API Tokens.
A webhook inbox for agents: one call returns a live URL. Mock, verify, inspect and replay.
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.

Rule engine with built-in simulation. 55 MCP tools for complete business rule lifecycle management.
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.
Give AI assistants the context behind client website feedback. Read comments, screenshots, replies, element details, and developer briefs; organize priorities, update statuses, and export feedback from authorized projects. Coding agents with repository access can investigate issues and prepare fixes for review. Connect through Streamable HTTP and browser OAuth using a Simple Commenter account.
Load testing and synthetic monitoring platform: test with Playwright, Browser Bot, or Protocol Bots.
Author and validate Calaf workspace seeds against the app's real importer. No account needed.
Lint a SKILL.md for frontmatter, structure, secrets and size. All 6 tools free.
Score any URL against a real design contract — 42 checks, A-F grade, token + motion validation.
Risk-scan a diff, flag AI-generated-code tells, find secrets. 5 of 7 tools need no account.
Runs your code against a contract; HELD or BROKE at the exact input. Deterministic. 0.10 USDC/call.
What is known to be broken in an MCP server or API operation, with the check that found it.
Observed facts on public MCP servers: protocol checks, tool changes, signed evidence. No verdicts.
A deterministic verification engine for agents. Proves a fix: fails on the old code, passes on new.
The world's first named AI prompt quality score. Score, optimize, and compare LLM prompts before they hit any model. Free tier available. Built on PEEM, RAGAS, G-Eval, and MT-Bench frameworks. x402-native on Base.
