Find a Slack message. See the documentation

Find a user by matching against their email. See the documentation

Find a user by their ID. Returns user profile information including name, email (requires users:read.email scope), timezone, and status. See the documentation

Read the recent message history from a specific channel. Accepts a channel ID or channel name (resolved automatically). Use this when you want to see a channel's latest messages — unlike **Search** which finds messages by keyword. Returns messages with text, timestamps (ts), reactions, and user IDs. Message timestamps can be used with **Get Thread Replies**, **Edit Message**, and **Add Reaction**. See the documentation

Retrieve comprehensive context about the authenticated Slack member, combining auth.test, users.info, users.profile.get, and team.info payloads. Returns the user’s profile (name variants, email, locale, timezone, status, admin flags), raw auth test data, and workspace metadata (domain, enterprise info, icons). Ideal when you need to confirm which user token is active, tailor messages to their locale/timezone, or ground an LLM in the member’s role and workspace before executing other Slack actions. See Slack API docs.

Return information about a file. See the documentation

Retrieve all replies in a message thread. Accepts a channel ID or channel name (resolved automatically). Use **Get Channel History** or **Search** to find the parent message's timestamp (thread_ts). Returns the parent message followed by all replies in chronological order. See the documentation

Retrieve the authenticated user's identity and workspace context. Returns user ID, name, email, timezone, profile, and workspace metadata. Call this first in any session to establish who you are — other tools like **Search** and **List Channels** can then filter by your user ID. See the documentation
