Check an A2A agent before you delegate, or an MCP server's measured conduct. Free, no key.
Risk-scan a diff, flag AI-generated-code tells, find secrets. 5 of 7 tools need no account.
Ensemble testing of web pages for accessibility, usability, and standards conformity
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.
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.
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).
Agentic testing: HyperExecute jobs, test failure triage, SmartUI visual diffs, a11y audits
Does an MCP server work for a stock client? By registry name or URL. Tool drift too. Free, no key.
Prompt evals over MCP: run a prompt on your dataset, score each output 1-5 with an LLM judge.
Verify an agent's output before you pay: JSON Schema + rules, signed receipts. Free during launch.
Simulated people test your pages, copy and sign-up flows, and say why they would leave.
Check whether AI assistants can reach, read and cite a public website. No account for 4 of 5 tools.
A digital audit for small-business websites: a score out of 100 and the main problems.
