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.
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.
HefestoAI checks AI-generated code before you ship it.
Ensemble testing of web pages for accessibility, usability, and web standards
Design quality gate for AI-generated UI: score any URL on 45 deterministic checks, A–F grade.
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.
Generate synthetic random user data for testing, demos, and development without using real persona.
