Built by Metorial, the integration platform for agentic AI.
Pin or unpin messages in a Slack channel, or list all pinned items. Pinned messages are highlighted and easily accessible by all channel members.
Invite users to or remove users from a Slack channel. Also supports listing current channel members and joining/leaving channels.
Look up a Slack user's profile and status. Search by user ID, email address, or list all workspace members.
Retrieve information about the Slack workspace (team), including its name, domain, email domain, and icon.
Create, update, enable, disable, or list user groups (also known as @mention handle groups) in Slack. Manage group membership by setting the full member list.
Send a message to a Slack channel, group DM, or direct message conversation. Supports plain text, rich Block Kit formatting, threaded replies, and ephemeral messages visible only to a specific user.
Schedule a message to be sent to a Slack channel at a future time. The message will be delivered automatically at the specified time.
Create, complete, delete, or list Slack reminders. Reminders notify a user at a specified time with a custom message.
Create, update, archive, unarchive, or configure a Slack channel. Combine multiple channel operations in a single action — create a new channel, rename it, set its topic/purpose, or manage its lifecycle.
Retrieve message history from a Slack channel, DM, or group DM. Supports pagination, time range filtering, and fetching thread replies.
Add, edit, remove, or list bookmarks (saved links) in a Slack channel. Bookmarks appear at the top of a channel for quick access.
Upload, list, get info about, or delete files in Slack. Upload text content as a file snippet, retrieve file metadata, or list files shared in a channel or by a user.
Update or delete an existing Slack message. Use this to edit message content or remove a message entirely.
Add, remove, or list emoji reactions on a Slack message. Use this to react to messages, remove existing reactions, or see all reactions on a message.
Search for messages across a Slack workspace by keyword query. Results include the message text, channel, sender, and timestamp. Requires a user token with the `search:read` user scope.
List Slack conversations (channels, private channels, DMs, and group DMs) accessible to the authenticated user or bot. Supports filtering by conversation type and pagination.
Retrieve stable metadata for a Slack conversation, including channel type, membership, topic, purpose, member count, and timestamps.
List or delete Slack messages that are scheduled to be sent later.
Search for files across a Slack workspace by keyword query. Requires a user token with the `search:read` scope.
Open or resume a Slack direct message or group direct message with one or more users.
Get, set, or clear the authorized Slack user's custom status.
Find Slack people by partial name, email, title, department, role, or other profile terms and return stable user IDs for messages and mentions. Use this query-driven discovery tool when the identity is not yet known; use get_user_info for a known user ID or exact email, a full profile lookup, or paginated member listing.
Consent-sensitive Real-time Search across public channels and the private channels, DMs, and group DMs accessible to the connected Slack user. Invoke this tool only after the user explicitly consents to searching private or direct-message content. It never expands access beyond conversations that connected user can already read. By default it searches messages across public channels, private channels, DMs, and group DMs.
Create a persistent Slack Canvas for meeting notes, plans, reports, or other structured documents. Canvas Markdown is distinct from Slack message mrkdwn.
Update the connected Slack user's profile fields without changing their status or email address.
Get a stable Slack permalink for a known message so users and downstream workflows can open it directly.
Insert, replace, delete, or rename Slack Canvas content. A replace operation without sectionId replaces the entire Canvas document and is destructive.
Download the contents of a Slack file by file ID. The result includes file metadata and a Slack permalink when available. Use manage_files with action "get" when only metadata is needed.
Find Slack channels by partial name, topic, purpose, or description with bounded Real-time Search. Use this query-driven tool to resolve a channel ID before reads or writes; use list_conversations when you need to browse and paginate the full accessible conversation list. Public-channel search is the default. Private-channel requests search only channels accessible to the connected user and require search:read.private.
Search messages and other discoverable content in public Slack channels with Real-time Search. This tool never searches private channels, DMs, or group DMs; use search_public_and_private only after the user has consented to that broader search. Results default to messages. File and user result types require the connected user token to have the matching granular search scopes.
Search workspace custom emoji by name or alias target before using one in a message or reaction.
Upload a document, image, or other binary file to Slack from base64-encoded bytes using Slack’s external upload flow. Use manage_files with action "upload" for text-snippet convenience uploads.
Find section IDs in a known Slack Canvas by section type or contained text so later edits can target a section safely. This does not read the complete Canvas document.
Read a known Slack thread, returning its parent message, replies, pagination state, and permalink. Use search or channel history first when the thread timestamp is unknown.
Identify the Slack user or bot connected to this integration and the workspace where it is authenticated.
Grant, change, or revoke user or channel access to a Slack List. Each invocation targets either users or channels, never both.
Replace one or more typed cell values in existing Slack List rows using stable row and column IDs.
Create one new row in an existing Slack List with optional typed field values.
Read a Slack user presence or set the connected actor presence to automatic or away. Get requires users:read; set requires users:write.
Permanently delete one Slack Canvas by its explicit ID. This action is destructive and irreversible.
Advance the connected Slack user's read marker in a channel, private channel, DM, or group DM to an exact message timestamp.
Create a Slack List for structured team tracking, such as an action register, project tracker, or task list.
Set or revoke access to a Slack Canvas for an explicit collection of users or channels.
List and paginate rows in a Slack List, including the stable row and column identifiers needed for later updates or deletion.
Permanently delete one or more explicitly identified rows from a Slack List. Multi-item deletion is all-or-nothing: if Slack cannot delete every requested item, the batch fails.
Retrieve one exact Slack channel-level message by timestamp with its permalink, full message content, hydrated author details when available, and optional bounded preceding context or thread replies.
Start a Slack List export, wait for the bounded asynchronous job to finish, and return the completed export file for download.
Read Do Not Disturb state or end/set DND for the connected Slack user. Reads require dnd:read; end, end_snooze, and set_snooze require dnd:write.
