Give your AI agents native, governed access to Slack. 87 purpose-built tools cover channels, messages, search, threads, files, canvases, users, presence and calls — under one policy layer.
No code. One Hub endpoint for every agent.
The DataGrout Slack MCP Server is a native Model Context Protocol server that exposes a Slack workspace as callable tools for AI agents. Agents can create and join channels, send messages as the connected user, search workspace history, read thread replies, work with files and canvases, look up people and presence, and register calls — through one governed endpoint that enforces side-effect policy and runs Warden preflight on every call.
87 tools spanning channels, messages, search and files
Message search across the workspace, not just one channel
Read and write allowed, scoped by your policy
Slack is a stream, not a database — so search, threads and channel structure do most of the work. The tools are grouped that way below; the full inventory is in your signed-in workspace.
Create the right room, join it, and understand who is in it before an agent posts.
The core loop: find what was said, read the thread, then reply in the right place.
The artefacts people drop into Slack, and the canvases that increasingly hold the real notes.
Who is who, who is online, and which group should own the follow-up.
For teams that run incident or standup calls inside Slack, agents can register and update them.
The small utilities that make an agent a useful teammate rather than a noise source.
Everything happens in the DataGrout Hub — no code, no per-agent configuration.
In DataGrout, open the Hub Server that will carry your integrations and click Add Integration.
Search for Slack, then select the native MCP Server integration.
Install through Slack OAuth using DataGrout-managed credentials or your own Slack app credentials. mTLS is optional.
Expose the channels and message tools the agent needs, then set side-effect and Warden policy.
OAuth2
Authorize through Slack’s OAuth flow using DataGrout-managed credentials or your own Slack app credentials.
mTLS (Mutual TLS)
Optional transport-level client identity, used alone or on top of the OAuth2 connection.
Slack payloads are verbose. The tools return the message and thread shape an agent needs, with the IDs required to reply in the same place.
The server ships with the same layered policy engine as every DataGrout integration. Security teams set the posture once; every agent inherits it.
Read and write are available. Side effects are governed by your policy, set per integration and inherited from the Hub Server above it. Sending a message is a write — grant it only to agents whose job is to speak.
PII access and destructive operations are separate policy switches, so you decide what an agent may reach. Useful when workspace history contains customer detail.
Slack is the most likely place for a crafted message to reach an agent. Warden screens every call in Off, Log only, Advisory or Enforce mode.
Integration policy inherits from the Hub Server and can only get stricter, Warden posture included. A child integration never weakens its parent.
Every execution can return a receipt, a pre-run credit estimate, a Cognitive Trust Certificate and a full execution summary — so an agent's work on your Slack data is always explainable.
Four patterns that show up again and again once a Slack connection is in place.
An agent follows an incident channel, pulls the thread history and linked posts, and drafts a timeline with owners and open actions as the channel quiets down.
Requests raised in a support channel are searched, deduplicated and turned into issues with the original thread linked — no copy-paste into another tool.
The agent reads the channels a team cares about, summarizes what changed since yesterday, and posts one digest instead of pinging the channel five times.
Ask why a decision was made. The agent searches workspace history, reads the threads around it and answers with the messages it relied on.
One Hub endpoint can carry all of them — same policy layer, same observability.
Add the Slack MCP Server to your DataGrout Hub and let agents read, summarize and respond where the team already works — with governance on every message.
