Slack

Communication

Two integration shapes from one Slack app. Outbound: the Slack MCP template lets your agent send messages, search channels, and manage workspaces. Inbound: an Agent Trigger with source = slack lets users mention the bot in a channel or DM and the agent replies in-thread. See [Agent Triggers](/docs/agent-triggers#slack) for the inbound setup.

How to Connect

1Go to the MCP Templates marketplace.
2Find the Slack template.
3Enter your Slack Bot token.
4Add the template to your agent.
