MCP-native AI browser testing for coding agents. Submit a URL + goal, get back action trail, bugs, screenshots, and WebM video your agent patches from directly. 43 tools, 12 AI evaluation personalities, combo tiers with auto-pause-on-bugs, throwaway email + SMS inboxes.
Check an A2A agent before you delegate, or an MCP server's measured conduct. Free, no key.
Screwtape.ai decides whether an AI agent is allowed to spend money, and keeps the proof. Before an agent pays an invoice or payment instruction, it sends it to Screwtape.ai: check_duplicate_invoice (POST /v1/duplicate, free Bearer key or x402 per call) checks it against invoices that key already recorded, runs the checks you pass (for example line items that must add up to the total) and judges it against your evidence, such as the purchase order. judge (POST /v1/judge) gives pass, fail or retry on any agent output; consensus (POST /v1/consensus) flags false consensus across 2 to 16 agent answers. Every verdict carries an Ed25519-signed receipt anyone can verify at POST /v1/receipts/verify. judge and consensus can be paid per call with x402 ($0.005 USDC on Base or Solana, no account); a free key gives 10 calls per UTC day.
Read the verification code (OTP) and test emails your app sends to a catch-all test hostname. Four read-only tools: list_domains, get_latest_otp, list_messages, get_message. Needs a MailBots API key from the 14-day free trial (no card, no DNS) or a paid plan. Setup: https://mailbots.top/docs/mcp
Tests whether your message will stick: grades readability and memorability before you send.
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.
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.
Real Android phones in the cloud for AI agents: give phones a task in plain words and get the answer
The beta program platform for hardware and IoT teams, who run structured betas with their own testers. Connect your AI assistant to build tasks and steps, screen applicants, triage tickets, read results and track tester progress. Actions that reach testers return a preview first and take effect only after confirmation. Sign in with OAuth, with read-only or read and write access. Stomio does not recruit testers.
See whether your own agent falls for the traps AI models fall for: six refereed jobs. No account.
Your AI designs live on the UX Pilot canvas or runs its design agent: reviews, React, video, media
Open a React Native app in a simulated phone: read the screen, tap, type, set device state.
The Decision Operations Platform for engineering teams
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.
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…).
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
Website monitoring for AI assistants: catches pages that look broken even when the site is up.
Check a landing page on a real phone and desktop, get the fixes, re-check after you publish.
Build, check and report on MIDAS CIVIL NX bridge models through the MIDAS IT Europe plugins.
Test inboxes for your app's sign-up and login emails: get the code or link, or why none came.
Run, debug, and triage tests from your IDE using natural language, no dashboard switching, no manual data transfers. The TestMu AI (formerly LambdaTest) MCP Server is a single remote server exposing four tool suites: HyperExecute — analyze your project, generate YAML configs and test runner commands, then monitor jobs and sessions. Automation — pull a TestID's details plus command, network, and console logs into one chat for instant root-cause analysis. Includes mobile app upload. SmartUI — explain pixel, layout, DOM, and perceptual changes in a visual regression run, with context-aware React/HTML/CSS fixes. Accessibility — audit any public URL or a local React app against WCAG and get ready-to-apply remediation steps. Connects over https://mcp.lambdatest.com/mcp using OAuth 2.1 — no API keys in your config. One-click install in Cursor; works with Claude, GitHub Copilot, Cline, and any MCP client. Tests execute on the TestMu AI cloud: 3,000+ browsers and 10,000+ real devices.

Check an online store's product catalog before you import it or send it to a shopping feed.
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.
Test your AI agents for security and safety weaknesses, and re-verify the fixes.
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.
Benchmark your own prompt on 100+ models with real API calls, then choose the winner by accuracy, cost, speed, or any mix of those.
Traffic Parrot simulates APIs and messaging. Request or withdraw a trial, read docs, send feedback.
Security scans for AI-built web apps, starting with Lovable. Verify ownership, run authorized scans, inspect findings, get AI-ready fix prompts and request retests. Uses OAuth with a Guarita account. Fix prompt access follows the account plan.
