Koskamo

Slack MCP Server

A community-operated MCP server that enables agents to monitor Slack channels, extract thread summaries, and manage workflows. It supports read-only shadow reports, scheduled briefs, and signed webhook deliveries for incident and support triage, allowing users to track open questions, owner gaps, and next actions without manual reconstruction of state.
