Communication MCP Servers

Slack MCP servers can help agents read or send team messages, but production workflows need clear channel scopes, approval rules, and redacted logs.

Start with the servers below, then review permissions, credentials, and client-specific setup before connecting production resources.

Communication

Send and read Slack messages across channels.

Use this category when the agent has a clear task that needs structured access, not as a default permission bundle for every chat.

Install one server, confirm the client can discover tools, run a harmless test, and document any tokens or paths as placeholders only.

Prefer read-only access first, avoid broad production credentials, and require review before write-capable or external-facing actions.

Before production access

Turn your selected slack servers into a reviewable deployment decision with permission scoring, prompt-injection checks, and rollout gates.
