Implementation Reference

• src/hebbian_mind/server.py:1419-1447 (handler)

  Handler logic for the "list_nodes" tool, implemented within the call_tool function in src/hebbian_mind/server.py. It calls db.get_all_nodes() and optionally filters by category.

  elif name == "list_nodes":
      category = arguments.get("category")
      nodes = db.get_all_nodes()
  
      if category:
          nodes = [n for n in nodes if n["category"] == category]
  
      by_category: Dict[str, List[Dict[str, Any]]] = {}
      for node in nodes:
          cat = node["category"]
          if cat not in by_category:
              by_category[cat] = []
          by_category[cat].append(
              {
                  "node_id": node["node_id"],
                  "name": node["name"],
                  "activation_count": node["activation_count"],
              }
          )
  
      return [
          types.TextContent(
              type="text",
              text=json.dumps(
                  {"success": True, "total_nodes": len(nodes), "categories": by_category},
                  indent=2,
              ),
          )
      ]

• src/hebbian_mind/server.py:1090-1096 (registration)

  Registration of the "list_nodes" tool in the list_tools function in src/hebbian_mind/server.py.

      name="list_nodes",
      description="List all concept nodes, optionally filtered by category.",
      inputSchema={
          "type": "object",
          "properties": {"category": {"type": "string", "description": "Filter by category"}},
      },
  ),

• src/hebbian_mind/server.py:480-490 (helper)

  Helper method in HebbianMindDatabase class that retrieves all nodes from the database.

  def get_all_nodes(self, limit: int = 10000) -> List[Dict]:
      """Get all concept nodes with safety limit.

      """
      cursor = self.read_conn.cursor()
      cursor.execute("SELECT * FROM nodes ORDER BY category, name LIMIT ?", (limit,))
      return [dict(row) for row in cursor.fetchall()]
