Indexbrain + Slack

CommunicationOAuth15 read, 15 writePro and Team

Indexbrain reads public channels only. Private channels require a separate invite. New messages are picked up on each sync cycle.

Every Slack action

Each action is set independently to always allow, ask every time, or disabled. The mode below is the default before anyone changes anything.

Action	What it does	Type	Default
Get reactionsslack.get_reactions	List every reaction (emoji, count, up to 50 reacting users) on a specific Slack message. Use slack.read_channel or slack.read_thread to find channel/message_ts first.	read	Always allow
List channel membersslack.list_channel_members	List the Slack user IDs who are members of a channel.	read	Always allow
List conversationsslack.list_conversations	List public and private Slack channels the bot can see (not DMs or group DMs) — use to resolve a channel name to an ID before reading or posting.	read	Always allow
List user conversationsslack.list_user_conversations	List Slack conversations (channels, private channels, DMs, group DMs) visible to the connecting user specifically — not just what the Indexbrain bot's been invited into. Requires the connecting user's Slack account to have granted extra permissions (reconnect Slack if this fails with slack_user_token_not_connected).	read	Always allow
List user groupsslack.list_user_groups	List Slack user groups (e.g. @eng, @oncall) and their mention syntax — use when composing a message that should mention a group.	read	Always allow
Read canvasslack.read_canvas	Read a Slack Canvas document's content by ID. Not tested against a live workspace; may not work as described.Built to the documented API but not yet exercised against a live account.	read	Always allow
Read channelslack.read_channel	Read the most recent messages in a Slack channel (public or private, must already be visible to the bot).	read	Always allow
Read fileslack.read_file	Read a Slack file's content by file ID — text content inlined directly (up to 10MB); binary/image/large files return metadata and a permalink instead. File IDs come from slack.read_channel or slack.read_thread.	read	Always allow
Read threadslack.read_thread	Read all replies in a Slack thread, given the channel and the parent message's timestamp.	read	Always allow
Read user profileslack.read_user_profile	Read a Slack user's profile (display name, email, title, status). Omitting user_id resolves to the connecting human (the 'current user') if known, else the Indexbrain bot's own profile.	read	Always allow
Search channelsslack.search_channels	Search Slack channels by name, topic, or purpose substring — client-side filter over the same channel list slack.list_conversations returns (Slack has no server-side channel-name-search endpoint for a bot).	read	Always allow
Search emojisslack.search_emojis	Search this workspace's custom emoji by name (comma-separate multiple terms). Standard Unicode emojis (thumbsup, heart, etc.) always exist and don't need to be searched.	read	Always allow
Search publicslack.search_public	Search Slack messages in public channels only. Requires the connecting user's Slack account to have granted extra permissions (reconnect Slack if this fails with slack_user_token_not_connected) — this acts as that specific person, not the Indexbrain bot.	read	Always allow
Search public and privateslack.search_public_and_private	Search Slack messages across public channels, private channels, and DMs the connecting user can see. Requires the connecting user's Slack account to have granted extra permissions (reconnect Slack if this fails with slack_user_token_not_connected) — this acts as that specific person, not the Indexbrain bot. Prefer slack.search_public unless private/DM content is actually needed.	read	Always allow
Search usersslack.search_users	Search Slack workspace members by name — client-side filter, no server-side name search exists for this either.	read	Always allow
Add reactionslack.add_reaction	Add a reaction (emoji, without colons, e.g. 'thumbsup') to a Slack message.	write	Ask every time
Complete file uploadslack.complete_file_upload	Finalize a Slack file upload reserved via slack.get_file_upload_url and optionally share it to conversations. Same 'not wired to a real file-bytes flow' caveat as slack.get_file_upload_url.	write	Ask every time
Create canvasslack.create_canvas	Create a Slack Canvas document from Canvas-flavored Markdown. Not tested against a live workspace; may not work as described. Not available on free Slack plans.Built to the documented API but not yet exercised against a live account.	write	Ask every time
Create conversationslack.create_conversation	Create a Slack channel (channel_name), or open a DM/group DM with the bot as a participant (user_ids only, no channel_name — 1 user = DM, 2-8 = group DM).	write	Ask every time
Create reminderslack.create_reminder	Create a Slack reminder targeting a specific user. user_id is required — a bot has no 'current user' to default to. `time` accepts natural language (e.g. 'tomorrow at 9am') or a Unix timestamp.	write	Ask every time
Delete messageslack.delete_message	Delete a Slack message — only works on messages the Indexbrain bot itself posted (Slack only allows deleting your own messages), not an arbitrary human's message.	write	Ask every time
Edit messageslack.edit_message	Edit a Slack message's text — only works on messages the Indexbrain bot itself posted.	write	Ask every time
Get file upload urlslack.get_file_upload_url	Reserve a Slack file upload slot, returning a file_id for slack.complete_file_upload. Note: this product's chat tool-calling has no path for a model to supply real file bytes mid-turn, so this pair of tools isn't wired to an actual file-attachment flow yet.	write	Ask every time
Invite to conversationslack.invite_to_conversation	Invite users to an existing public or private Slack channel.	write	Ask every time
Join conversationslack.join_conversation	Join an existing public Slack channel — cannot join a private channel the bot hasn't been invited to.	write	Ask every time
Leave conversationslack.leave_conversation	Leave a public or private Slack channel.	write	Ask every time
Post messageslack.post_message	Post a message to a Slack channel or user via the org's connected Slack bot.	write	Ask every time
Schedule messageslack.schedule_message	Schedule a Slack message for future delivery — does NOT send immediately (use slack.post_message for that). post_at must be a Unix timestamp at least 2 minutes in the future, max 120 days out.	write	Ask every time
Update canvasslack.update_canvas	Update an existing Slack Canvas. WARNING: action='replace' without section_id overwrites the ENTIRE canvas. Call slack.read_canvas first to get real section ids. Not tested against a live workspace; may not work as described.Built to the documented API but not yet exercised against a live account.	write	Ask every time
Update user profileslack.update_user_profile	Update the connecting Slack user's own profile (status, display name, title). Requires the connecting user's Slack account to have granted extra permissions (fails with slack_user_token_not_connected otherwise) — this acts as that specific person, not the Indexbrain bot. Cannot set a profile image or change active/away presence.	write	Ask every time

Every write stops for a human

Write actions are off entirely until an admin turns them on, and even then each one halts the run and asks before it happens. There is no auto-approve mode anywhere in the product, on any plan. Disabling an action goes further: it is never offered to the model, so it cannot be asked for.
