  Registration and handler implementation for the 'get_info' MCP tool.

    'get_info',
    'Get INFO stats for the active instance. Contains all health data: memory, clients, replication, keyspace, stats (hit rate, ops/sec), and server info. Optionally filter to a section: server|clients|memory|stats|replication|keyspace.',

      section: z.string().optional().describe('INFO section to filter (server, clients, memory, stats, replication, keyspace)'),
      instanceId: z.string().optional().describe('Optional instance ID override'),
    },
    async ({ section, instanceId }) => {
      const id = resolveInstanceId(instanceId);
      const data = await apiFetch(`/mcp/instance/${id}/info`) as Record<string, unknown>;
      if (section && data[section] !== undefined) {
        return {
          content: [{ type: 'text' as const, text: JSON.stringify({ [section]: data[section] }, null, 2) }],
