A hosted MCP endpoint that returns deterministic fake data so you can prototype agent workflows without spinning up a backend. You get 12 tools covering common patterns like list_users, get_product, create_order, send_email, and search_knowledge_base. All data is seeded from your inputs, so the same request returns the same mock response. Free tier gives you 30 requests per minute and 500 per day, rate limited by IP and user agent fingerprint. Supports streamable HTTP natively, which means it works in Claude Desktop, Cursor, and Claude Code without needing mcp-remote as a proxy. Built with the MCP SDK, Faker.js for seeded data generation, and Upstash Redis for sliding window rate limits.
