Slack
Channels, DMs and workflow posts for your agent.
Overview
Send messages, read channel history, search, post into threads, manage reactions. Scoped per member so agent messages are attributed to the human on whose behalf they run.
Why this matters
- Agent-authored messages carry a visible badge per workspace policy.
- Thread-aware — the agent can continue a thread context-aware.
Tools exposed
4 toolssend_messagePost a message to a channel or DM.

Read-only and list_* calls are free in all plans. Standard calls consume 1 credit. Heavy operations (bulk writes, cross-resource) may consume more — see docs.
Quickstart
- 1
Install from your workspace
Click Install on this page. You'll land in Aladia signed in and the connector will be added to your team.

Members link their identity
Each team member authorises their own Slack user so calls are attributed per-human.

Frequently asked questions
How much does the Slack connector cost?
The Slack MCP connector is billed at €1.20 per 1,000 tool calls on the Aladia Team plan. Read-only list endpoints such as list_channels are counted but included in your team's shared credit pool.
Does the Slack connector support OAuth?
Yes. Each team member authenticates with their own Slack account, so every call carries the real human actor in the audit trail — no shared service account.
How many tools does the Slack connector expose?
4 tools covering send_message, list_channels, search_messages and 1 more. Each tool is versioned and invocations are attributed to the calling team member.
Can I try the Slack connector before subscribing?
Yes — new workspaces get 1,000 credits free, enough to explore Slack and a few other connectors before you upgrade. Install takes one click from your dashboard once you have an Aladia account.
