Browse Files

List files shared in a channel or across the workspace. Accepts a channel ID or channel name (resolved automatically). Filter by file type (e.g. images, pdfs, snippets). Returns file metadata including name, type, size, and download URL. See the documentation

Find Message

Get Channel History

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

Get Current User

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.

Get File

Return information about a file. See the documentation

Get Thread Replies

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

Get User Details

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
