Implementation Reference

• src/index.ts:498-510 (handler)

  MCP CallToolRequest handler case for 'list_personas' that calls listPersonas() helper and formats the response as text content.

  case 'list_personas': {
    const personas = await listPersonas();
    return {
      content: [
        {
          type: 'text',
          text: personas.length > 0
            ? `사용 가능한 페르소나:\n${personas.map(p => `- ${p}`).join('\n')}\n\n사용법: @persona:${personas[0]} 형식으로 참조하세요.`
            : '저장된 페르소나가 없습니다.',
        },
      ],
    };
  }

• src/index.ts:374-380 (schema)

  Tool schema definition in ListToolsRequestHandler, including name, description, and empty input schema (no parameters). Serves as registration.

    name: 'list_personas',
    description: '사용 가능한 모든 페르소나 목록을 조회합니다',
    inputSchema: {
      type: 'object',
      properties: {},
    },
  },

• src/index.ts:71-78 (helper)

  Core helper function that reads the persona directory (~/.persona) and returns array of persona names from .txt files.

  async function listPersonas(): Promise<string[]> {
    try {
      const files = await fs.readdir(PERSONA_DIR);
      return files.filter(f => f.endsWith('.txt')).map(f => f.replace('.txt', ''));
    } catch (error) {
      return [];
    }
  }
