Implementation Reference

• src/tools/room.ts:238-245 (handler)

  Executes the bulc_modify_room tool by parsing arguments with ModifyRoomSchema and sending a 'modify_room' command to the BULC client.
  case "bulc_modify_room": { const validated = ModifyRoomSchema.parse(args); result = await client.sendCommand({ action: "modify_room", params: validated, }); break; }
• src/tools/room.ts:187-194 (schema)

  Zod validation schema for the inputs to the bulc_modify_room tool.
  const ModifyRoomSchema = z.object({ id: z.string(), name: z.string().optional(), x: z.number().optional(), y: z.number().optional(), width: z.number().positive().optional(), depth: z.number().positive().optional(), });
• src/tools/room.ts:107-146 (schema)

  MCP tool schema definition for bulc_modify_room, including input schema, description, and annotations.
  { name: "bulc_modify_room", description: "Modify properties of an existing room. Only specified properties will be changed. " + "Get room IDs from bulc_list_rooms first.", inputSchema: { type: "object" as const, properties: { id: { type: "string", description: "Room ID to modify (from bulc_list_rooms)", }, name: { type: "string", description: "New room name", }, x: { type: "number", description: "New X coordinate of bottom-left corner (cm)", }, y: { type: "number", description: "New Y coordinate of bottom-left corner (cm)", }, width: { type: "number", description: "New width (cm)", }, depth: { type: "number", description: "New depth (cm)", }, }, required: ["id"], }, annotations: { readOnlyHint: false, destructiveHint: true, }, },
• src/index.ts:54-58 (registration)

  Registers all tools, including bulc_modify_room via roomTools inclusion in allTools, for the MCP ListToolsRequest.
  server.setRequestHandler(ListToolsRequestSchema, async () => { return { tools: allTools, }; });
• src/index.ts:68-71 (handler)

  Dispatches calls to bulc_modify_room (and other room tools) to the handleRoomTool function.
  // Room tools if (name.startsWith("bulc_") && name.includes("room")) { return await handleRoomTool(name, safeArgs); }
