YAPI MCP Server

A Model Context Protocol (MCP) server for interacting with a YAPI instance. This server enables LLMs to retrieve API documentation details from your YAPI projects.

Features

• List interface categories and basic interface info within a project.
• Get detailed information for a specific interface by its ID.

Tools

1. yapi_list_interfaces

   • Lists all interface categories and the interfaces within them for a specific YAPI project.
   • Input:
     • project_token (string): The token for the YAPI project (found in YAPI project settings -> Tokens).
   • Returns: A JSON string containing an array of categories, each with a list of simplified interface objects (id, title, path, method, status).

2. yapi_get_interface_details

   • Gets detailed information for a specific YAPI interface by its ID.
   • Input:
     • project_token (string): The token for the YAPI project.
     • interface_id (number): The ID of the specific YAPI interface (you can find this ID in the URL when viewing an interface in YAPI).
   • Returns: A JSON string containing the detailed interface information (request/response parameters, headers, body schemas, etc.).

Setup

Prerequisites

1. A running YAPI instance.
2. Access to the project token(s) for the YAPI projects you want to interact with. You can find this in your YAPI project's "Settings" -> "Tokens" section.
3. Node.js and npm installed on the machine where you'll run the server or build the Docker image.

Configuration

The server requires the base URL of your YAPI instance to be set via the YAPI_URL environment variable.
