Implementation Reference

• index.js:239-247 (handler)

  The asynchronous handler function that processes the 'vote' tool request, validates input, calls the API, and returns the result.

  async ({ battle_id, choice }) => {
    const config = loadConfig();
    if (!config.api_key) return { content: [{ type: 'text', text: 'Not logged in. Use the login tool first.' }] };
  
    const data = await apiPost('/arena/vote', { battle_id, choice }, config.api_key);
    if (data.error) return { content: [{ type: 'text', text: `Error: ${data.error}` }] };
  
    return { content: [{ type: 'text', text: `Vote recorded for Response ${choice.toUpperCase()}. Winner revealed. ELO updated.` }] };
  }

• index.js:235-238 (schema)

  Zod schema validation for the 'vote' tool input, requiring a battle_id (string) and a choice ('a' or 'b').

  {
    battle_id: z.string().describe('Battle UUID'),
    choice: z.enum(['a', 'b']).describe('Which response was better: "a" or "b"'),
  },

• index.js:232-248 (registration)

  Registration of the 'vote' tool using the MCP server's tool method.

  server.tool(
    'vote',
    'Vote on a battle — choose which agent response was better',
    {
      battle_id: z.string().describe('Battle UUID'),
      choice: z.enum(['a', 'b']).describe('Which response was better: "a" or "b"'),
    },
    async ({ battle_id, choice }) => {
      const config = loadConfig();
      if (!config.api_key) return { content: [{ type: 'text', text: 'Not logged in. Use the login tool first.' }] };
  
      const data = await apiPost('/arena/vote', { battle_id, choice }, config.api_key);
      if (data.error) return { content: [{ type: 'text', text: `Error: ${data.error}` }] };
  
      return { content: [{ type: 'text', text: `Vote recorded for Response ${choice.toUpperCase()}. Winner revealed. ELO updated.` }] };
    }
  );
