Tips for using this MCP server

Implementation Reference

• src/McpService.ts:465-488 (handler)

  The primary handler for the MCP 'tips' tool. It invokes StoryService.tips(), joins the text list, and attaches images as base64 if available, returning formatted tool content.

  const tips = () => {
    return Effect.gen(function* () {
        const res = yield* StoryService.tips()
        const content = [{type: "text", text: res.textList.join('\n-------\n')} as ToolContentResponse]
        if (res.imagePathList.length > 0) {
          yield* Effect.forEach(res.imagePathList, a => {
            return Effect.async<Buffer, Error>((resume) => fs.readFile(path.join(__pwd, a), (err, data) => {
              if (err) {
                resume(Effect.fail(err))
              }
              resume(Effect.succeed(data));
            })).pipe(Effect.andThen(b => {
              content.push({
                type: "image",
                data: Buffer.from(b).toString('base64'),
                mimeType: 'image/png'
              } as ToolContentResponse)
            }))
          })
        }
        return content
      }
    )
  }

• src/StoryService.ts:168-273 (helper)

  Core logic generating tips text based on system configuration (practice mode, db setup, API keys, Python/rembg, SNS accounts, etc.). Returns textList and imagePathList.

      const tips = () => {
        //  informationの文
        //  1. practiceモードであればそれを示す 解除にはGoogle map api keyが必要であることを示す
        //  2. dbパスを設定するとアプリを終了しても現在地と行き先が記録されることを示す
        //  2. 画像AIのkeyがなければ 画像API keyがあればアバターの姿を任意に作れることを示す
        //  3. pythonがインストールされていなければ pythonをインストールするとアバターの姿を合成できる
        //
        //  以下はランダムで表示
        //  - 画像AIのkeyがあってかつpromptを変更したことがなければ変更可能を案内する
        //  - snsアカウントがあればpostが出来ることを案内する
        //  - bsアカウントがあれば相互対話が出来ることを案内する
        //  - 二人称モードに切り替えると二人称会話で操作できる(ただし可能な限り)
        //  - リソースに詳細があるのでリソースを取り込むと話やすい。プロジェクトを起こしてある程度会話を調整できる

• src/McpService.ts:138-144 (schema)

  Tool schema definition: no input parameters required, provides title and description.

  name: "tips",  //  pythonがあったらよいとか、db設定がよいとか、tipsを取得する。tipsの取得を行うのはproject側スクリプトとか、script batchとか
  title: "Tips for using this MCP server",
  description: "Inform you of recommended actions for your device",
  inputSchema: {
    type: "object",
    properties: {}
  }

• src/McpService.ts:1014-1015 (registration)

  Registers the handler in the tool switch statement for dispatching 'tips' calls.

  case "tips":
    return tips()

• src/McpService.ts:1138-1142 (registration)

  Registers the dynamic tools list handler, which includes the 'tips' tool via makeToolsDef.

  server.setRequestHandler(ListToolsRequestSchema, async () => {
    return await DbService.getSysMode().pipe(Effect.andThen(env => makeToolsDef(env)),
      aiRuntime.runPromise
    )
  });
