Conformance checker for MCP servers. Free, no key, verdicts recomputable and re-measured daily.
Run EPUBCheck for EPUB specification errors and compare two exports.
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.
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.
Verify before your agent acts on data it paid for. Signed verdicts, checkable offline, via x402.
Accessibility and WCAG data for your own websites: fix lists, live checks, and fix validation.
Generate synthetic random user data for testing, demos, and development without using real persona.
Workflow planning, recovery checkpoints, coordination, fixtures, and compatibility tools for agents.
Test-inbox API for email and SMS: create inboxes, long-poll messages, extract OTPs and links.
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).
Whether a registry MCP server works for a stock client, and what changed in its tools. Free, no key.
Hosted Python sandbox for package runtime verification: pip install and usable-import evidence.
Lint a SKILL.md for frontmatter, structure, secrets and size. All 6 tools free.
Risk-scan a diff, flag AI-generated-code tells, find secrets. 5 of 7 tools need no account.
Prompt evals over MCP: run a prompt on your dataset, score each output 1-5 with an LLM judge.
Score any URL against a real design contract — 42 checks, A-F grade, token + motion validation.
Probe a signup URL you own and score whether an AI agent can sign up unaided.
Compare two versions of a JSON row list: what was added, removed or changed, field by field.
AI-callable tools for API mocking, testing, monitoring, security, and automation.
