Implementation Reference

• build/tools/graph/read-graph.js:19-33 (handler)

  The handler function that implements the core logic of the 'read_graph' tool. It invokes knowledgeGraphManager.readGraph() and formats the entire knowledge graph as a JSON string in the MCP content format.
  export const readGraphHandler = async (args) => { try { const graph = await knowledgeGraphManager.readGraph(); return { content: [{ type: "text", text: JSON.stringify(graph, null, 2) }] }; } catch (error) { console.error("Error in read_graph tool:", error); throw error; } };
• build/tools/graph/read-graph.js:7-15 (schema)

  The tool definition object containing the name, description, and input schema (empty object since no parameters are required). This is used during registration.
  export const readGraphTool = { name: "read_graph", description: "Read the entire knowledge graph", inputSchema: { type: "object", properties: {}, required: [], }, };
• build/core/registry.js:136-150 (registration)

  The code block in the auto-registration logic that discovers and registers the tool by calling toolRegistry.register(tool, handler) for discovered Tool/Handler exports, including 'read_graph' from read-graph.js.
  for (const { tool, handler } of tools) { if (this.registeredTools.has(tool.name)) { if (this.config.verbose) { console.log(`⏭️ Outil déjà enregistré: ${tool.name}`); } continue; } try { toolRegistry.register(tool, handler); this.registeredTools.add(tool.name); registeredCount++; if (this.config.verbose) { console.log(`✅ Outil enregistré automatiquement: ${tool.name} (${path})`); } }
• build/knowledge-graph/manager.js:93-95 (helper)

  The underlying helper method in KnowledgeGraphManager that loads and returns the entire knowledge graph from the memory file.
  async readGraph() { return this.loadGraph(); }
• build/core/registry.js:216-219 (registration)

  'read_graph' is listed in the expected tools array used for verification after auto-registration.
  'delete_relations', 'read_graph', 'search_nodes', 'open_nodes',
