Public APIs MCP Server

English | 中文

A Model Context Protocol (MCP) server that provides intelligent access and management functionality for the public-apis database.

🚀 Project Overview

Public APIs MCP Server is a professional MCP server implementation designed to provide developers with convenient public API discovery, search, and integration services. Through the standardized MCP protocol, you can easily integrate rich public API resources into various AI assistants and development tools.

Core Features

• 🔍 Smart Search: Multi-dimensional API search by category, keywords, authentication method, etc.
• 🛡️ Security Filtering: Security filtering including HTTPS support, CORS configuration, etc.
• 🎯 Smart Recommendations: Intelligently recommend the most suitable APIs based on project requirements
• 💻 Code Generation: Automatically generate API integration code in multiple programming languages
• 📊 Statistical Analysis: Provide detailed API data statistics and analysis
• 🔄 Real-time Sync: Support synchronizing the latest API data from GitHub repositories

🛠️ Usage

Basic Configuration

After the server starts, it will communicate with MCP clients through standard input/output. You can configure this server in AI assistants or development tools that support the MCP protocol.

MCP Client Configuration Example

{
  "mcpServers": {
    "public-apis-mcp": {
      "command": "node",
      "args": ["path/to/public-apis-mcp/dist/index.js"]
    }
  }
}

Or

{
  "mcpServers": {
    "public-apis-mcp": {
      "command": "npx",
      "args": ["-y", "@weilei_kyle/public-apis-mcp"]
    }
  }
}

API Details and Statistics

get_api_details

Get detailed information for a specific API

Parameters:

• apiName (string, required): API name

get_category_list

Get a list of all available API categories

get_random_api

Randomly recommend an API

Parameters:

• category (string, optional): Limit random selection within a specific category

get_api_statistics

Get API quantity statistics

analyze_auth_requirements

Analyze the distribution of APIs by different authentication methods

Smart Recommendations

recommend_apis_for_project

Recommend suitable APIs based on project requirements

Parameters:

• projectType (string, required): Project type description
• requirements (array, optional): List of project requirements
• limit (number, optional): Limit the number of recommended APIs, default 5

find_alternative_apis

Find alternative API options

Parameters:

• functionality (string, required): Required functionality description
• limit (number, optional): Limit the number of results returned, default 5

Code Generation

generate_api_integration_code

Generate integration code examples for selected APIs

Parameters:

• apiName (string, required): API name
• language (string, optional): Programming language (javascript, python, curl), default javascript

Data Management

sync_repository_data

Synchronize the latest API list from GitHub repository

Important Note: This interface currently uses a manual synchronization mechanism to sync the latest data from the public-apis repository to the local server. This mainly ensures data stability and access speed.

How it works:

• Manually trigger fetching the latest API data from the GitHub repository
• Cache data to the local server to improve query performance
• Support both incremental updates and forced full synchronization modes
• Return detailed synchronization status reports after completion

Parameters:

• force (boolean, optional): Whether to force re-synchronization, default false
  • false: Only perform incremental synchronization when data is expired
  • true: Force full data synchronization, ignoring local cache

Usage Recommendations:

• It's recommended to perform a forced synchronization (force: true) before first use
• Periodically perform incremental synchronization during daily use to get the latest data
• Use forced synchronization to reset local cache if data anomalies are found

check_new_apis

Check recently added new APIs

Parameters:

• days (number, optional): Check new APIs added in recent days, default 7 days
