Frequently asked questions

What is the OpenAPI MCP server?

The OpenAPI MCP server is an Developer Tools Model Context Protocol server that lets Claude Code, Cursor, Windsurf, VS Code with Copilot, and other MCP-compatible AI agents access any API using OpenAPI specs. It exposes OpenAPI's capabilities as tools the AI can call directly from your editor or CLI.

How do I install OpenAPI MCP with Claude Code?

The fastest way is the MCPizy CLI: run `mcpizy install openapi` and MCPizy will add the server to your `.claude.json` automatically. You can also install it manually by adding an entry under `mcpServers` in `.claude.json` with the command `npx -y openapi-mcp` and restarting Claude Code.

Is OpenAPI MCP free?

Yes. The OpenAPI MCP server is free and open source. You may still need a OpenAPI account or API key to connect the server to the underlying service, but the MCP layer itself has no MCPizy subscription cost.

Does OpenAPI MCP work with Cursor and Windsurf?

Yes. Any MCP-compatible client works — including Claude Code, Claude Desktop, Cursor (via `.cursor/mcp.json`), Windsurf, VS Code with Copilot Chat, and custom agents built on the MCP SDK. The same install command targets all of them; only the config file path differs.

What can I do with OpenAPI MCP?

Once installed, your AI agent can access any API using OpenAPI specs directly inside your conversation. Typical use cases include asking Claude Code or Cursor to run OpenAPI operations, inspect results, chain OpenAPI with other MCP servers (see our Workflow Recipes), and automate repetitive developer tools tasks without leaving your editor.
