From the repository
Paste the URL https://mockmcp.io/mcp into Claude Code, Cursor, or Claude Desktop. All three clients support Streamable HTTP natively—no proxy needed. Tools are invoked by name (e.g., list_users or create_order) and all data is deterministically seeded from your inputs.

}What it is
MockMCP is a hosted Model Context Protocol endpoint that returns realistic fake data for prototyping agents. Paste one URL into Claude Code, Cursor, or Claude Desktop — no signup, no config, no API keys. 12 pre-built tools covering the scenarios in most agent tutorials. Built for developers who want to design and test agent workflows before the real backend exists. ## Quickstart Claude Code ```bash claude mcp add --transport http mockmcp https://mockmcp.io/mcp Cursor — add to ~/.cursor/mcp.json: { "mcpServers": { "mockmcp": { "url": "https://mockmcp.io/mcp" } } } Claude Desktop — Settings → Connectors → Add custom connector → paste https://mockmcp.io/mcp. All three clients speak Streamable HTTP natively. No mcp-remote proxy required.
