Slack MCP server
Bring Slack into your agent: read channels and threads, post messages and replies, react, and look up users — the team communication layer for agents.
How to read this: tool names here are observed from a live tools/list handshake. The Risk label is a heuristic inferred from the tool name (write/destructive verbs), not from executing the tool — a conservative guess, not a verified capability. We never escalate risk from a description. Found one that's wrong? Tell us — we fix on report.

The access this server can exercise, inferred from its verified tools — not a declared OAuth scope.

This is one server. A loadout combines the right servers, governance, and proven plays for a whole job — assembled deliberately, not tool-dumped.
