Conformance checker for MCP servers. Free, no key, verdicts recomputable and re-measured daily.
Parse WebVTT, SRT, or TTML for conformance, timing, overlaps, line length, and reading speed.
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).
Load testing and synthetic monitoring platform: test with Playwright, Browser Bot, or Protocol Bots.
Test curl retries locally or inspect remote 429/503 Retry-After traces; optionally share findings.

What is known to be broken in an MCP server or API operation, with the check that found it.
Observed facts on public MCP servers: protocol checks, tool changes, signed evidence. No verdicts.
Explore Upforge services and evidence, or submit a prototype for a human-approved static fit check.
Point Claude Code, Qwen Code, Cursor, or any MCP client at https://docs.jmeter.ai/api/mcp and your agent answers JMeter questions grounded in this documentation, with a source link for every answer. Free, no API key, no signup.
Whether a registry MCP server works for a stock client, and what changed in its tools. Free, no key.
Probe a signup URL you own and score whether an AI agent can sign up unaided.
Compare two versions of a JSON row list: what was added, removed or changed, field by field.
Test FIX from Claude, ChatGPT, or Cursor: free sandbox FIX sessions or your own FIXSIM instances.

Check what a paid x402 endpoint or MCP server delivered, from probes anyone can repeat.
MCP tool observatory: do registry servers answer, and are their answers true? No key.
Scan any website or MCP server for agent readiness: 0-100 score, a fix per failing check. Free.
