Slack Basics
Read channels, search messages, and post to Slack via the Slack MCP server.
MCP requirement
Requires MCP server slack to be configured. If not available:
MCP server 'slack' not configured — this skill requires it
Check with /mcp in Claude Code. The server name in tool calls will be mcp__<plugin>_slack__<tool>.
Operations
| Goal | Tool | Key params |
|------|------|-----------|
| List channels | slack_list_channels | limit, cursor |
| Read channel history | slack_get_channel_history | channel_id, limit |
| Search messages | slack_search_messages | query, count |
| Post to channel | slack_post_message | channel_id, text |
| Reply to thread | slack_reply_to_thread | channel_id, thread_ts, text |
| Get thread replies | slack_get_thread_replies | channel_id, thread_ts |
| Look up user | slack_get_user_profile | user_id |
Execution sequence
- Resolve channel: if given a name, list channels and match — never assume the ID
- Read or search as needed; keep
limit≤ 20 for history reads - If posting, confirm channel ID before calling the post tool
- Report success with channel name and message timestamp, or surface the error
Fallback
If the slack MCP server is not connected, stop and state the requirement clearly. Do not attempt workarounds via web browsing or other tools.
