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.

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.
AI-callable tools for API mocking, testing, monitoring, security, and automation.
Deploy production REST APIs from JSON schemas in seconds. Manage projects, schemas, and deployments.
Check whether an MCP server answers, what its tools claim, and whether that claim has changed.
Webhook URLs for AI agents: receive, wait for, replay, sign and verify webhooks (Stripe, GitHub…).
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.
