none.api - OpenAPI Explorer MCP Server

English Español


English

Professional OpenAPI explorer for the Model Context Protocol (MCP).

What is this?

This MCP server allows Large Language Models (LLMs) like Claude or Cursor to dynamically explore, understand, and interact with any API that has an OpenAPI/Swagger specification.

Unlike other servers that map every endpoint to a tool (which can overwhelm the model's context), none.api acts as an intelligent inspector. It allows the model to:

  • List available endpoints and methods.
  • Search operations by functional tags.
  • Retrieve detailed information and documentation for specific routes.
  • Extract precise JSON Schemas for requests and responses.
  • Understand the API structure without manual documentation pasting.

Optimized for backends following the hono-template structure.

Installation

Run the server directly without installation:

npx @nonetss/none.api

Global Installation

npm install -g @nonetss/none.api

MCP Configuration

Add this to your claude_desktop_config.json or equivalent (like Cursor):

{
  "mcpServers": {
    "none.api": {
      "command": "npx",
      "args": ["-y", "@nonetss/none.api"],
      "env": {
        "OPENAPI_URL": "http://localhost:3000/doc"
      }
    }
  }
}

Features

  • Endpoint Listing: Overview of all available routes.
  • Tag Discovery: List functional sections of the API.
  • Granular Schemas: Fetch specific JSON Schemas for precise code generation.
  • Dynamic URLs: Ability to point to different OpenAPI specs on the fly.

¿Qué es esto?

Este servidor MCP permite a los modelos de lenguaje (como Claude o Cursor) explorar, entender e interactuar dinámicamente con cualquier API que tenga una especificación OpenAPI/Swagger.

A diferencia de otros servidores que mapean cada endpoint a una herramienta (lo que puede saturar el contexto del modelo), none.api actúa como un inspector inteligente. Permite al modelo:

  • Listar endpoints y métodos disponibles.
  • Buscar operaciones por etiquetas funcionales.
  • Obtener información detallada y documentación de rutas específicas.
  • Extraer esquemas JSON precisos para peticiones y respuestas.
  • Entender la estructura de la API sin necesidad de pegar la documentación manualmente.

Optimizado para backends que siguen la estructura de hono-template.

Zhipu Web SearchZhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
