## Install

Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

# 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.

## Hero protocols

- `protocols/search-messages.md` — full-text search with Slack operators (`from:`, `in:`, `before:`, `after:`)
- `protocols/channel-read.md` — recent N messages in a channel, with thread-reply count
- `protocols/thread-read.md` — parent + all replies for a thread
- `protocols/find-user.md` — search workspace users by name / email / handle (see § failure-modes for tool-name verification status)

## Workflow pattern

A typical search-messages invocation:

```
mcp__slack__search_messages({
  "query": "OKR in:#engineering after:2026-05-01",
  "count": 20,
  "sort": "timestamp"
})
```

Returns a JSON array of message records. Format per the protocol's `## Output` section.

## Failure modes

See `references/failure-modes.md` — OAuth scope, workspace visibility (private vs public channels), rate limits, Real-Time Search API quotas, tool-name verification status.
