Implementation Reference

• src/tools/evac.ts:1023-1029 (handler)

  The handler case within handleEvacTool function that executes the tool by sending the 'get_evac_summary' action command to the BULC client with empty parameters.

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

• src/tools/evac.ts:406-419 (schema)

  Tool specification defining the name, description, input schema (empty object since no parameters), and annotations (read-only).

  {
    name: "bulc_get_evac_summary",
    description:
      "Get evacuation result summary including total time, " +
      "per-agent exit times, and statistics.",
    inputSchema: {
      type: "object" as const,
      properties: {},
    },
    annotations: {
      readOnlyHint: true,
      destructiveHint: false,
    },
  },

• src/index.ts:40-51 (registration)

  Aggregates evacTools (which includes bulc_get_evac_summary) into allTools, which is returned by the MCP ListToolsRequestHandler to register all available tools.

  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:135-137 (registration)

  Top-level MCP CallToolRequestHandler routes calls to bulc_get_evac_summary (matching 'bulc_*evac*') to the handleEvacTool dispatcher.

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