Implementation Reference
- main.py:525-596 (handler)The core handler function for the 'get_subject_details' MCP tool. It is decorated with @mcp.tool(), which handles both definition and registration. Fetches subject details from the Bangumi API endpoint /v0/subjects/{subject_id}, processes the response, handles errors, and formats a detailed text summary including name, type, summary, rating, tags, collection stats, and image URL.
