Implementation Reference

• src/tools/evac.ts:910-916 (handler)

  Handler case that executes the tool logic by dispatching a 'list_evac_stairs' command to the BULC client.

  case "bulc_list_evac_stairs": {
    result = await client.sendCommand({
      action: "list_evac_stairs",
      params: {},
    });
    break;
  }

• src/tools/evac.ts:95-107 (schema)

  Tool schema definition including name, description, input schema (empty object), and annotations indicating read-only.

  {
    name: "bulc_list_evac_stairs",
    description:
      "List all configured evacuation stairs for multi-level buildings.",
    inputSchema: {
      type: "object" as const,
      properties: {},
    },
    annotations: {
      readOnlyHint: true,
      destructiveHint: false,
    },
  },

• src/index.ts:40-51 (registration)

  Includes evacTools (containing bulc_list_evac_stairs) in the complete list of MCP tools served via ListToolsRequest.

  const allTools = [
    ...contextTools,      // 8 tools: spatial context, home info, levels, undo/redo, save
    ...roomTools,         // 5 tools: create, create_polygon, list, modify, delete
    ...wallTools,         // 5 tools: create, create_rectangle, list, modify, delete
    ...furnitureTools,    // 5 tools: catalog, place, list, modify, delete
    ...fdsDataTools,      // 7 tools: get, fire_source, detector, sprinkler, hvac, thermocouple, clear
    ...meshTools,         // 5 tools: list, create, auto, modify, delete
    ...simulationTools,   // 4 tools: get_settings, time, output, ambient
    ...fdsRunTools,       // 6 tools: preview, validate, export, run, status, stop
    ...resultTools,       // 5 tools: open_viewer, list_datasets, point_data, aset, report
    ...evacTools,         // 25 tools: setup, stairs, agents, run, results, advanced features
  ];

• src/index.ts:54-58 (registration)

  Registers the handler for listing all tools, exposing bulc_list_evac_stairs schema to MCP clients.

  server.setRequestHandler(ListToolsRequestSchema, async () => {
    return {
      tools: allTools,
    };
  });

• src/index.ts:134-137 (registration)

  Routes tool calls matching 'bulc_*evac*' (including bulc_list_evac_stairs) to the evac handler function.

  // EVAC tools
  if (name.startsWith("bulc_") && name.includes("evac")) {
    return await handleEvacTool(name, safeArgs);
  }
