Risk-scan a diff, flag AI-generated-code tells, find secrets. 5 of 7 tools need no account.
Simulate cloud architectures before provisioning. 9 free demo tools; an API key unlocks all 62.
Diagnose why an AI agent failed and get the verified fix instantly. Free, no token.
Scan URLs or HTML for WCAG 2.2 accessibility violations. 75-rule manifest, severity-weighted score, shareable HTML/CSV/JSON reports. Tools: scan_url, scan_html, get_report, list_rules.

Ensemble testing of web pages for accessibility, usability, and standards conformity
An open-source benchmark of how well LLMs solve nonogram puzzles, from 5x5 to 20x20.
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).
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.
Load testing and synthetic monitoring platform: test with Playwright, Browser Bot, or Protocol Bots.
AI users run real tasks on your live site and show where they get stuck, with a replay of every step
