"Information about servers or server-related topics" matching MCP connectors:
GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
Conformance checker for MCP servers. Free, no key, verdicts recomputable and re-measured daily.
GodPrompt MCP + Agent Skill for coding agents with TDD, debugging, verification, and task routing.
Parse WebVTT, SRT, or TTML for conformance, timing, overlaps, line length, and reading speed.
Run EPUBCheck for EPUB specification errors and compare two exports.
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).
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.
Runs your code against a contract; HELD or BROKE at the exact input. Deterministic. 0.10 USDC/call.
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.
AI-callable tools for API mocking, testing, monitoring, security, and automation.
Explore Upforge services and evidence, or submit a prototype for a human-approved static fit check.
Whether a registry MCP server works for a stock client, and what changed in its tools. Free, no key.
Verify artifacts, hand off public state, and record, check and find evidence about capabilities.
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.
Pay-per-call MCP server. Vetted human experts review AI-generated content (text, images, video, audio, social posts), audit reasoning chains, run prepublish safety checks, and gate high-stakes actions for human approval. 7 paid tools at $1.00 each plus 4 free tools (list_offerings, list_expert_profiles, get_result, verify_certificate). Payment via x402, USDC on Base mainnet. Approved outputs receive an on-chain Taste content certificate downstream agents verify before consuming.
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 HTTP 429/503 retries and Retry-After with server-observed traces; share synthetic findings.
MCP server for visual regression testing: triage a PR's UI diffs from your coding agent.
