GodPrompt MCP + Agent Skill for coding agents with TDD, debugging, verification, and task routing.
Parse WebVTT, SRT, or TTML for conformance, timing, overlaps, line length, and reading speed.
Run EPUBCheck for EPUB specification errors and compare two exports.
Diagnose why an AI agent failed and get the verified fix instantly. Free, no token.
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.
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.
Author and validate Calaf workspace seeds against the app's real importer. No account needed.
Generate synthetic random user data for testing, demos, and development without using real persona.
Your agent built the page. Simulated buyers test it, and Mimiq calls which version to ship.
Runs your code against a contract; HELD or BROKE at the exact input. Deterministic. 0.10 USDC/call.
