How to Set Up and Use MCP Link
MCP Link is an open-source OpenAPI-to-MCP adapter written in Go that automatically converts any OpenAPI specification into a fully functional MCP server, exposing every API endpoint as an MCP tool without requiring code modifications. It supports authentication via API keys and bearer tokens, path filtering to expose only specific endpoints, and SSE transport for easy integration with any MCP client. Pre-built conversions are available for popular services like Brave, DuckDuckGo, Figma, GitHub, Notion, Slack, Stripe, TMDB, YouTube, and Home Assistant, making it the fastest way to give AI agents access to any REST API that has an OpenAPI spec.
Prerequisites
- Go 1.21 or later installed (for building from source)
- An OpenAPI specification URL or file for the API you want to expose
- API credentials (key or bearer token) for the target API
- An MCP-compatible client such as Claude Desktop or Cursor
Clone the repository
Clone the MCP Link repository and enter the project directory.
git clone https://github.com/automation-ai-labs/mcp-link.git
cd mcp-linkDownload Go dependencies
Fetch all required Go modules before building.
go mod downloadStart the MCP Link server
Run the server on a local port. The server accepts OpenAPI spec URLs and target API base URLs as query parameters.
go run main.go serve --port 8080 --host 0.0.0.0Construct the SSE endpoint URL
Build the URL for your target API by passing the OpenAPI spec URL (s=), target base URL (u=), and auth header (h=) as query parameters.
# Example for GitHub API:
# http://localhost:8080/sse?s=https://raw.githubusercontent.com/github/rest-api-description/main/descriptions/api.github.com/api.github.com.yaml&u=https://api.github.com&h=Authorization:Bearer%20YOUR_GITHUB_TOKENConfigure your MCP client
Add the SSE endpoint URL to your MCP client configuration. No command-line binary is needed — the client connects via SSE URL.
MCP Link Examples
Client configuration
Connect Claude Desktop to MCP Link's SSE endpoint for the Slack API. Replace the OpenAPI spec URL, base URL, and auth header with your target API's values.

}Prompts to try
Once connected to an API via MCP Link, these prompts demonstrate what you can do with the automatically generated tools.
- "List all channels in my Slack workspace that I'm a member of."
- "Search GitHub for open issues in the 'anthropics/anthropic-sdk-python' repo labeled 'bug'."
- "Get the details for Stripe customer ID cus_ABC123 including their payment methods."
- "Search Notion for pages containing 'product roadmap' and show me the top results."
- "What movies are currently playing in theaters? Use the TMDB API."Troubleshooting MCP Link
Server starts but the MCP client cannot find any tools
Check that the 's=' OpenAPI spec URL is publicly accessible and returns valid JSON or YAML. Test it by opening the URL in a browser. Invalid or private spec URLs result in empty tool lists.
API calls fail with 401 Unauthorized
Verify the 'h=' parameter format: it must be 'header-name:value-prefix', e.g., 'Authorization:Bearer YOUR_TOKEN'. URL-encode special characters in the query string. Confirm your API token has the required scopes.
Too many tools are being generated from a large OpenAPI spec
Use the 'f=' path filter parameter to include only specific endpoints. For example, 'f=+/repos/**' includes only GitHub repository endpoints and '-/admin/**' excludes admin routes.
