Implementation Reference
- sourcesage/mcp_server.py:439-502 (handler)The handler function implementing the get_knowledge_statistics tool. It computes statistics on the knowledge graph (entities by type/language, relations, patterns, style conventions) and returns a formatted string report. Registered via @self.mcp.tool() decorator.
