MCP Link - Seamlessly Integrate Any API with AI Agents
π§© Architecture
π€ 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.
π 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
π Online Version
Try our hosted version at mcp-link.vercel.app to quickly convert and test your APIs without installation.
π Quick Start
Installation
# Clone repository
git clone https://github.com/automation-ai-labs/mcp-link.git

# 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 fileu=
- Base URL of the target APIh=
- Authentication header format, in the format ofheader-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.
π 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
