Example Use Cases

• 1

  Human approval or clarification during task execution.

• 2

  Request missing credentials or information from a human.

• 3

  That require asynchronous human input via Slack threads.

Description

This MCP server acts as a bridge between Claude Code and Slack, allowing Claude to request human input during tasks by posting questions to a Slack channel and waiting for replies in the thread. It supports multiple concurrent sessions, ensuring replies are routed correctly to the waiting Claude instance. The daemon runs persistently in Docker, handling Slack events and forwarding replies to session processes that block until a response is received, enabling seamless human-in-the-loop interactions without polling.
