概要

What is Mockmcp?

Mockmcp is a hosted Model Context Protocol endpoint that returns realistic fake data for prototyping agent workflows. It provides 12 pre-built tools covering common agent tutorial scenarios, requires no signup, configuration, or API keys, and is aimed at developers who want to design and test agent interactions before a real backend exists.

How to use Mockmcp?

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.

Key features of Mockmcp

  • 12 pre-built tools for common agent scenarios.
  • Deterministic fake data seeded from client inputs.
  • Works with Claude Code, Cursor, and Claude Desktop.
  • Native Streamable HTTP transport — no proxy required.
  • No signup, no config, no API keys.
  • Free tier with rate limits (30 req/min, 500 req/day).

Use cases of Mockmcp

  • Prototyping an agent that queries users, products, or orders.
  • Testing multi-step agent workflows before backend integration.
  • Verifying tool call formatting and error handling in an MCP client.
  • Demonstrating agent capabilities in demos or tutorials without live data.

FAQ from Mockmcp

What does Mockmcp do that a real backend can't?

Mockmcp returns realistic but entirely fake data, so you can iterate on agent prompts and logic without depending on a live service or worrying about test data pollution.

Are there any dependencies or runtime requirements?

No. Mockmcp is a hosted service; you only need an MCP client that supports Streamable HTTP (e.g., Claude Code, Cursor, Claude Desktop).

Where does the data come from, and is it persistent?

All data is generated on the fly and seeded from your tool inputs. The same input always returns the same output, but nothing is stored or persisted across sessions.

What are the rate limits on the free tier?

30 requests per minute and 500 requests per day per hashed fingerprint. Exceeding these returns a 429 status with retry_after_seconds and an upgrade URL.

What transport and authentication does Mockmcp use?

Mockmcp uses Streamable HTTP. No authentication is required — no API key, no token.
