Poku Labs (Human-in-the-loop)

This MCP server provides human-in-the-loop tools for AI agents, enabling them to request real-time human assistance via SMS when encountering edge cases, unclear situations, or scenarios requiring human judgment. Built by Poku Labs, it integrates with AI agent platforms like n8n, Retell AI, and Vapi through MCP client access or custom API tool calls, allowing agents to pause mid-conversation, send questions to human managers, receive responses, and continue seamlessly. The implementation supports voice, SMS, and text agents across various workflows, making it valuable for customer support scenarios where agents need approval for discounts, lead qualification handoffs, policy exception handling, or confirming warm transfers before routing to human representatives.
