"Understanding VS Code Agents or Extensions" matching MCP connectors:
GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
Check an A2A agent before you delegate, or an MCP server's measured conduct. Free, no key.
Contract-change authorization for AI agents: preflight a change to an API or MCP contract, get a signed decision, and verify the receipt offline. Only a granted change can proceed.
Traffic Parrot simulates APIs and messaging. Request or withdraw a trial, read docs, send feedback.
A webhook inbox for agents: one call returns a live URL. Mock, verify, inspect and replay.
Behind Check and GAIP Watch, and Diagnose: A2A, MCP and OpenAPI checks with a dated change log.
Discovery registry for AI agents: 660+ APIs, MCP servers and CLIs, each health-checked every 6 hours with real requests — full initialize + tools/list handshakes for MCP, real calls for APIs — plus response-schema validation that catches responses which parse fine but are missing a required field.
Scores how well AI agents will use your API, 0-100, from its OpenAPI spec. Free and read-only.
Webhook, email, WebSocket and tunnel testing for AI agents: capture, wait, verify, replay.
AI-Powered Java/Spring Boot code review API with Alipay AI Pay support.
API documentation drifts away from the running service, so consumers integrate against a contract nobody keeps. Routebase keeps API design, testing, mocking and documentation on one living source of truth, and this MCP server exposes that workspace to AI agents. Agents can design endpoints, write and run test suites, manage mock servers and publish documentation, always under the permissions of the connected Routebase account.
What is known to be broken in an MCP server or API operation, with the check that found it.
Free agent tests (no account or payment); paid ping.
Anonymous webhook capture, inspection, waiting, and response configuration for AI agents.
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.
Webhook URLs for AI agents: receive, wait for, replay, sign and verify webhooks (Stripe, GitHub…).
Paid OpenAPI audit and API change detection for agents. $0.10 USDC per analysis via x402 on Base.
Webhook capture bins for agents: get a URL, wait for webhooks, set replies, verify signatures.
Web search for agents, one x402 payment: real results, provider failover, signed receipt. $0.01.
Test FIX from Claude, ChatGPT, or Cursor: free sandbox FIX sessions or your own FIXSIM instances.
40+ developer tools from Context7, Code Runner, Python Execute, NPM Sentinel, PlantUML, and Microsoft Learn. Docs lookup, code execution, security scanning. Starts at $0.01/call. Get your API key at app.xpay.sh or xpay.tools
