Mockzilla MCP server. Mock any OpenAPI spec locally with Claude, Cursor, or Gemini CLI.
Most developer tooling work still happens through a UI a human drives. Mockzilla MCP server moves it into the conversation instead. Mockzilla MCP server. Mock any OpenAPI spec locally with Claude, Cursor, or Gemini CLI.
MCP server for Mockzilla - an open-source API mock server for OpenAPI specifications. Let Claude Code, Claude Desktop, Cursor, or Gemini CLI install Mockzilla, inspect OpenAPI specs, and spin up realistic local mock APIs in seconds. No account required for local use.
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
The server publishes 4 tools. What each one is for:
get_context — list_simslist_catalog_products — deploy_mock_from_catalogdeploy_mock_from_spec — deploy_mock_from_urlCursor — Easiest: Settings -> MCP Servers -> Add new MCP server and fill in:Configuration is passed through the environment: MOCKZILLA_TOKEN, MOCKZILLA_MCP_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Mockzilla's toolset — get_context, list_catalog_products, deploy_mock_from_spec and 1 more — is a fair guide to whether it matches your workflow. It is maintained by mockzilla; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
