slack-automate

Read-only Slack access via the official Slack MCP server (GA 2026-02). Tool calls return structured JSON — no UI scraping, no locale tables, no browser daemon.

⚠️ First-MCP-session verification needed (v0.2.0): the mcp__slack__find_user tool name is assumed against likely Slack MCP exposure but unverified — find-user may fail on first invocation if the actual tool name differs (e.g. mcp__slack__users_lookup). On first run of any protocol, ask Claude Code to list the slack MCP server's exposed tools and reconcile with allowed-tools + protocol bodies. See references/failure-modes.md §"Tool name verification needed" for the one-shot procedure.

Prerequisites

One-time setup:

1. Run /collab-setup and accept the slack row (records intent + verifies prerequisites).
2. Run /mcp add slack once — this triggers Claude Code's native OAuth pre-registration flow against the Slack MCP endpoint. Token refresh is handled automatically thereafter.

If a protocol fails with an auth error, re-run /mcp add slack to refresh the OAuth grant.
