Mcp Link Convert Any Openapi V3 Api To Mcp Server

What is MCP-Link?

MCP-Link is an innovative tool designed to convert any OpenAPI V3 API into a fully functional MCP (Microservices Communication Protocol) server. This allows developers to easily create and manage microservices, enhancing the scalability and efficiency of their applications. By leveraging the power of OpenAPI specifications, MCP-Link simplifies the process of API integration and management.

Features of MCP-Link

• OpenAPI V3 Compatibility: MCP-Link supports the latest OpenAPI V3 specifications, ensuring that developers can work with modern APIs seamlessly.
• Easy Conversion: The tool automates the conversion process, allowing users to transform their OpenAPI definitions into an MCP server with minimal effort.
• User-Friendly Interface: MCP-Link provides an intuitive interface that makes it easy for developers to navigate and utilize its features effectively.
• Scalability: Built with scalability in mind, MCP-Link allows developers to manage multiple microservices without compromising performance.
• Documentation Generation: Automatically generates comprehensive documentation for the created MCP server, making it easier for teams to understand and use the API.

How to Use MCP-Link

1. Access the Tool: Visit the MCP-Link website to access the tool.
2. Upload OpenAPI Specification: Start by uploading your OpenAPI V3 specification file. MCP-Link will read the file and prepare for conversion.
3. Configure Settings: Adjust any necessary settings to tailor the MCP server to your specific needs.
4. Convert to MCP Server: Initiate the conversion process. MCP-Link will generate the MCP server based on your OpenAPI definition.
5. Deploy and Manage: Once the conversion is complete, deploy your MCP server and manage it through the provided interface.

MCP Link - Convert Any OpenAPI V3 API to MCP Server

🧩 Architecture

🤔 Why MCP Link?

There is a notable gap in the current AI Agent ecosystem:

• Most MCP Servers are simple wrappers around Web APIs
• Functionality interfaces may not be complete, depending on developer implementation
• Manual creation of MCP interfaces is time-consuming and error-prone
• Lack of standardized conversion processes

MCP Link solves these issues through automation and standardization, allowing any API to easily join the AI-driven application ecosystem.

🌟 Key Features

• Automatic Conversion: Generate complete MCP Servers based on OpenAPI Schema
• Seamless Integration: Make existing RESTful APIs immediately compatible with AI Agent calling standards
• Complete Functionality: Ensure all API endpoints and features are correctly mapped
• Zero Code Modification: Obtain MCP compatibility without modifying the original API implementation
• Open Standard: Follow the MCP specification to ensure compatibility with various AI Agent frameworks

🚀 Quick Start

Installation

### Clone repository
git clone https://github.com/automation-ai-labs/mcp-link.git
cd mcp-openapi-to-mcp-adapter

### Install dependencies
go mod download

Running

### Specify port
go run main.go serve --port 8080 --host 0.0.0.0

Parameter Description

• s= - URL of the OpenAPI specification file
• u= - Base URL of the target API
• h= - Authentication header format, in the format of header-name:value-prefix
• f= - Path filter expressions to include or exclude API endpoints. Syntax:
  • +/path/** - Include all endpoints under /path/
  • -/path/** - Exclude all endpoints under /path/
  • +/users/*:GET - Include only GET endpoints for /users/{id}
  • Multiple filters can be separated by semicolons: +/**:GET;-/internal/**
  • Wildcards: * matches any single path segment, ** matches zero or more segments

Usage in AI Agents

{
  "mcpServers": {
    "@service-name": {
      "url": "http://localhost:8080/sse?s=[OpenAPI-Spec-URL]&u=[API-Base-URL]&h=[Auth-Header]:[Value-Prefix]"
    }
  }
}

These URLs allow any API with an OpenAPI specification to be immediately converted into an MCP-compatible interface accessible to AI Agents.

📋 Future Development

• MCP Protocol OAuthflow: Implement OAuth authentication flow support for MCP Protocol
• Resources Support: Add capability to handle resource-based API interactions
• MIME Types: Enhance support for various MIME types in API requests and responses
