Testing, benchmarking and auditing autonomous AI agents — methods, harnesses, evidence
Give AI assistants the context behind client website feedback. Read comments, screenshots, replies, element details, and developer briefs; organize priorities, update statuses, and export feedback from authorized projects. Coding agents with repository access can investigate issues and prepare fixes for review. Connect through Streamable HTTP and browser OAuth using a Simple Commenter account.
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.
Load testing and synthetic monitoring platform: test with Playwright, Browser Bot, or Protocol Bots.
Accessibility and WCAG data for your own websites: fix lists, live checks, and fix validation.
Author and validate Calaf workspace seeds against the app's real importer. No account needed.
Simulate, test, and analyze cloud architectures without deploying real infrastructure. Cloud World Model enables AI agents to model cloud environments, evaluate architecture behavior and costs, run failure and chaos simulations, and explore infrastructure scenarios across cloud providers.
Kilotest leverages 10 rule engines to test web pages for front-end quality (accessibility, usability, and standards conformity) and report results with specifiable granularity.
Moderated usability testing: read sessions, notes, transcripts, reports, and draft test scenarios.
Test-inbox API for email and SMS: create inboxes, long-poll messages, extract OTPs and links.
Free platform to test MCP clients without installing anything. Create mock tools with dynamic templates, configurable delays, conditions (if/then), and response sequences. Supports JSON-RPC 2.0 over Streamable HTTP. Built-in text_echo and json_echo tools. Rate-limited tiers: anonymous (5 calls/min, 1 mock tool), registered (10 calls/min, 4 mock tools), premium (60 calls/min, unlimited). Zero setup — no install, no registration required.

Hosted Python sandbox for package runtime verification: pip install and usable-import evidence.
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.
Scan pasted Stripe webhook/checkout code for common integration bugs.
Scan a web page's markup for the WCAG failures ADA demand letters cite most often.
AI-callable tools for API mocking, testing, monitoring, security, and automation.
Probe a signup URL you own and score whether an AI agent can sign up unaided.
Scan GitHub-hosted AI skills for vulnerabilities: prompt injection, malware, OWASP LLM Top 10.
Resolve whether an uncertain side-effecting action completed before software retries it.
Test HTTP 429/503 retries and Retry-After with server-observed traces; share synthetic findings.
