Frequently asked questions
What is a Communication MCP server?
A Communication MCP server exposes tools like Slack and Notion as agent-callable functions — posting messages, reading channels, and updating docs with per-channel and per-page scopes.
Can agents read every channel?
No. You grant access channel by channel and page by page. Agents only see what you explicitly scope them to.
What do teams use this for?
Common patterns: agents posting revenue milestones to Slack, summarizing support queues each morning, and syncing meeting notes into Notion project docs.
