- How to work with Slack via MCP. Use when the user wants to read, search, send, or manage Slack messages, channels, threads, canvases, or user profiles.
Finding and reading
Search messages: slack_search_public with keywords and modifiers: in:#channel, from:@user, after:YYYY-MM-DD
Channel history: slack_search_channels to resolve ID → slack_read_channel with date range
Full thread: get thread_ts from search → slack_read_thread
Private channels / DMs: slack_search_public_and_private — confirm with user first
Sending and drafting
Post to channel: resolve ID via slack_search_channels → draft with slack_send_message_draft → slack_send_message
DM: slack_search_users to resolve user ID → slack_send_message
Thread reply: slack_send_message with thread_ts
Scheduled: slack_schedule_message
Canvases
Create: slack_search_channels → slack_create_canvas
Read: slack_read_canvas
Update: slack_read_canvas → slack_update_canvas
Users
Profile / status: slack_search_users → slack_read_user_profile
Summarizing
Channel digest: slack_read_channel with date filters → summarize decisions and action items
Incident / topic: slack_search_public → slack_read_thread on key threads → compile summary
Best Practices
- Resolve channel names and usernames to IDs before acting
- Use
thread_tsfor replies — avoid posting to main channel unnecessarily - Use
slack_send_message_draftbefore sending important or broadcast messages - Always confirm before sending on the user's behalf
- Use date filters with
slack_read_channelon high-traffic channels - Confirm before using
slack_search_public_and_private

Use when work should span one or more detached tasks but still behave like one job with a single owner context. TaskFlow is the durable flow substrate under authoring layers like Lobster, ACPX, plugins, or plain code. Keep conditional logic in the caller; use TaskFlow for flow identity, child-task linkage, waiting state, revision-checked mutations, and user-facing emergence.
