Implementation Reference

src/metabase_mcp_server.py:1296-1307 (handler)

The main handler function for the 'delete_metabase_group' tool. Takes a group_id parameter and makes a DELETE request to the Metabase API endpoint '/api/permissions/group/{group_id}' to delete the specified group. Returns a confirmation dictionary.

src/metabase_mcp_server.py:1295-1295 (registration)
The @mcp.tool() decorator registers the delete_metabase_group function as an MCP tool, making it available for invocation through the Model Context Protocol.

src/metabase_mcp_server.py:162-247 (helper)

Helper function that executes HTTP requests to the Metabase API. Used by delete_metabase_group to perform the actual DELETE request. Handles connection errors, response parsing, and ensures proper error handling with custom exceptions (MetabaseConnectionError, MetabaseResponseError).
