Connecting Apidog Projects to AI

For teams working with API specifications within Apidog projects, the server can connect directly to your project using your API access token. This approach is ideal for accessing private API specifications and working collaboratively within a team.

To configure this connection:

1. Generate an API Access Token from your Apidog account settings

2. Get your Apidog Project ID from the project's basic settings

3. Configure your MCP-compatible IDE with the following settings:

{
  "mcpServers": {
    "API specification": {
      "command": "npx",
      "args": [
        "-y",
        "apidog-mcp-server@latest",
        "--project=<project-id>"
      ],
      "env": {
        "APIDOG_ACCESS_TOKEN": "<access-token>"
      }
    }
  }
}

This configuration enables your AI assistant to access and understand your API specifications, allowing for more intelligent code generation and assistance.

Connecting Published API Documentation to AI

For developers working with publicly available API documentation, Apidog MCP Server can connect to online documentation published through Apidog. This method doesn't require an API access token and is perfect for external developers consuming your APIs or for accessing public API documentation.

To enable this connection:

1. Enable the MCP Service in your Apidog project's documentation settings

2. Copy the MCP Configuration provided in the documentation interface
