Check an A2A agent before you delegate, or an MCP server's measured conduct. Free, no key.
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.
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).
Configure mobile bug reporting and investigate saved bug reports with your coding assistant. Manage apps and reporter settings, get Android/iOS/React Native setup guidance, and read report metadata, screenshots and logs. OAuth with an existing BugScreen account and workspace. Docs: https://www.bugscreen.app/docs/mcp
Verify an artifact an AI agent produced — schema, emptiness, provenance and mandate authority — before you accept the work or pay for it. Ed25519-signed and verifiable without this service; 20 checks a day free, then 0.005 USDC per call over x402.
Disposable email inboxes for AI agents: create an address, wait for mail, read OTP codes and links.
Diagnose why an AI agent failed and get the verified fix instantly. Free, no token.
Validate CSV columns, find duplicates and invalid values, and clean files with explicit rules. Row-level reports, no stored files. Run the fixed free sample without a key. Custom CSV: EUR 9 for 100 operations, valid 90 days, no subscription. Setup: https://import-check-production.up.railway.app/docs/
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.
An open-source benchmark of how well LLMs solve nonogram puzzles, from 5x5 to 20x20.
Agentic testing: HyperExecute jobs, test failure triage, SmartUI visual diffs, a11y audits
Prompt evals over MCP: run a prompt on your dataset, score each output 1-5 with an LLM judge.
Read visual design reviews captured on live web pages with the Website Feedback Tool Chrome extension: comments, CSS selectors, computed styles, console and network errors, and screenshots, so a coding agent can apply the fixes. Tool calls require the agent key from the extension (Connect AI agent) as an Authorization: Bearer header.
Does an MCP server work for a stock client? By registry name or URL. Tool drift too. Free, no key.
Free open check: can an AI agent reach checkout on this store? Advisory; ARC stops before payment.
Runs an eight-stage isolation test against your staging Supabase and issues a signed attestation.
Simulated people test your pages, copy and sign-up flows, and say why they would leave.
Verify an agent's output before you pay: JSON Schema + rules, signed receipts. Free during launch.
Signed deterministic checks for supplied JSON invoices, OpenAPI API contracts and JSON events.
