Overview
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
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.
