Visual regression testing over MCP: upload screenshots, review diffs, approve. No CI needed.
Verify before the agent pays. Screwtape is an independent check on agent work before a payment goes out: invoices, duplicate invoices and reconciliation, with a signed receipt for your auditor. It is independent of your agent's own model and vendor, with no stake in your agent passing. - judge: pass, fail or retry verdict on one agent output, with a score, reasons and a next_step. Optional deterministic checks: required fields, types, formats, sums, regex. - check_duplicate_invoice (/v1/duplicate): opt-in duplicate-invoice check using keyed fingerprints. - consensus: scores agreement across 2 to 16 agent answers and flags false consensus. - Advisory mode: recommends approve, review or return; a person decides. - Receipts: Ed25519-signed. The receipt proves what was checked, when, and the verdict. Verify via POST /v1/receipts/verify or offline; export via GET /v1/receipts/export. - Judged content isn't stored unless you opt in. Free key: 100 calls/day. Or $0.005 USDC per call via x402 on Base or Solana, no key needed.

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.
Check public web pages for common WCAG 2.2 accessibility issues from your MCP client. The free scan_url tool needs no account and returns a score, severity breakdown, WCAG references, affected elements and fix guidance. Automated checks do not establish conformance; manual review is still required. Optional authenticated tools support monitoring your own sites. Documentation: https://allyproof.com/docs/mcp
AI QA for coding agents. TestOptim explores your web app, generates end-to-end tests and reports bugs with severity. Over MCP, Claude Code, Cursor or Copilot can start a test run on just the pages they changed, poll the result, and read the issues it found. Authenticate with a TestOptim API key as a Bearer token.
GodPrompt MCP + Agent Skill for coding agents with TDD, debugging, verification, and task routing.
EU cookie-consent & tracker audit, run like a real first-time visitor (EU proxies). Free quick check, no account. Finds trackers and tracking cookies before consent, missing first-layer Reject, what still fires after Reject, Google Consent Mode v2 state per signal, plus Google Fonts/YouTube/Maps/reCAPTCHA. Every finding comes with the exact request as evidence and a concrete fix, in 13 languages. Weekly monitoring, white-label PDF for agencies, private share links. Works with any CMP (Cookiebot, Usercentrics, Complianz, CookieYes, Borlabs…).
Audit public webpages and supplied markup for HTML, CSS, SEO, JSON-LD, and link issues.
Open a React Native app in a simulated phone: read the screen, tap, type, set device state.
Cloud Android 14 phones that Claude, Claude Code, Cursor and Codex can use over MCP. Ready in ~15 s. Plain-English tasks return pass/fail, steps, screenshots and video. 1¢ per phone-minute, AI included, 100 free minutes a month.
QA platform for agents: coverage signals, in-repo test plans, verified tests and release governance.
See which AI models fall for traps in everyday jobs, and check or scan any MCP server, skill or package before your agent installs it. No sign-in; read-only; returns structured data.
Test a web app in a real browser from plain English. Passed, failed or cannot verify, with evidence.
Run accessibility, contrast, and design token audits and file QA issues from your AI coding tool.
Website checker for AI coding agents. Measures your site in a real browser, with evidence.
Disposable, receive-only email inboxes for AI agents. Create an address, wait for the verification email, and get the one-time code or magic link back as structured fields. Long-polling wait_for_email with sender and subject filters, attachments, sanitised HTML, and restore for later password resets. OAuth 2.1, hosted in the EU, cannot send email.
Per-SDK verdict matrix for signed A2A Agent Cards: which signatures verify in each SDK.
Connect Claude, ChatGPT, Cursor or any MCP client to Ybug. Read bug reports with screenshots, console logs and network requests, then triage them in chat.
Assign Linear, Jira or GitHub issues to an AI coding agent team that plans, builds, reviews, tests.
Runs an eight-stage isolation test against your staging Supabase and issues a signed attestation. Needs a RowAttest API key: Authorization: Bearer rak_... (create one on the API keys page in the app).
Read in-app bug reports, crashes, screenshots and tickets from mobile, web and TV apps.
AI-native customer research and AI usability testing. Search customer feedback and full conversation transcripts; get themes, ratings, recommendations and quotes; compare projects and trends; generate charts. Plan, review and launch AI usability tests on any public URL or design and get prioritized issues with paste-ready fix prompts for coding agents. OAuth 2.0 with dynamic client registration; sign in with a TheySaid account (free plan available).
Website monitoring for AI assistants: catches pages that look broken even when the site is up.
Agent website testing: browser QA, visual regression, Markdown extraction, and security checks.
Create and manage test cases, test runs and results in Testiny from your AI assistant.
Technical SEO audit tools over MCP. Wrendex crawls a site with 140+ checks (broken links, redirects, canonicals, hreflang, sitemaps, structured data, duplicate trackers, render-blocking resources, Core Web Vitals page weight) and exposes crawl runs, issues and fix lists as tools so coding agents like Claude Code, Cursor and Codex can audit and fix a site. Stateless Streamable HTTP; authenticate with a Wrendex bearer token from https://wrendex.com/docs.
Preflight FactoryTalk View import CSV files before import. Detects deterministic schema, row, field, and compatibility issues and returns structured exceptions for review.
Compare a website before and after a migration: missing pages, content changes, visual diffs.
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.
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.
