Swagger Template FAQs

Question 1

What is Swagger Template?

Accepted Answer

Swagger Template is a minimalist Python project that converts any OpenAPI/Swagger specification into a FastMCP-powered Model Context Protocol (MCP) server. This enables AI copilots like Claude Code and Codex to interact with and call your existing HTTP API.

Question 2

How does Swagger Template help AI copilots use my API?

Accepted Answer

By creating an MCP server from your OpenAPI/Swagger specification, the template exposes your API's operations in a format that MCP-compatible AI copilots can understand. This allows them to discover, validate, and execute calls to your API without manual setup.

Question 3

What do I need to get started with Swagger Template?

Accepted Answer

You'll need an existing OpenAPI 3.x or Swagger 2.0 specification (saved as `swagger.yaml`), Python, and `uv` (recommended) or `pip` for dependency management. You'll also configure your target API's `base_url`.

Question 4

Is Swagger Template compatible with both Claude Code and Codex CLI?

Accepted Answer

Yes, the template is designed for seamless integration with both Claude Code (Claude Desktop) and Codex CLI. It provides clear instructions for configuring each client to connect to your locally running MCP server via simple JSON configuration edits.

Question 5

How do I update my API's definition after making changes?

Accepted Answer

To update your API's definition, simply modify your `swagger.yaml` file to reflect the changes. FastMCP will automatically regenerate the tool definitions based on the updated specification the next time the MCP server is launched or restarted, ensuring your AI copilots always have the latest API schema.
