How we rank theseShowHide
Official connectors we host come first, then verifiedentries — ones where we hold the server’s own repository or the vendor’s own docs and have checked the link resolves — then the rest by how many agent-callable tools they expose. A listing on another directory doesn’t count as verification. We don’t publish install counts for third-party servers, because we have no way to measure them, and anything its maintainers have archived says so on the card. A dash in the Tools column means we haven’t listed that server’s tools yet, not that it has none.
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.
