Common Room MCP server

What the model can do

Common Room: a contact looked up by email with title, company, segments and tags, organizations, segments with their sizes, tags, and community activity by contact, organization or date; can create or rename segments, add named contacts or organizations to a segment and tag or untag them, delete named contacts, and file a right-to-be-forgotten erasure.

Acts, when you ask

These change something in Common Room. The model is told to use them only when you ask for exactly that, and each one is granted by name: per team on a shared connection, by the owner on a personal one.

• commonroom_create_segmentCreates an empty segment (a saved list) of contacts or organizations in Common Room, visible to everybody in the room.
• commonroom_rename_segmentRenames a Common Room segment; its members and id stay as they are.
• commonroom_update_contactsApplies one change to up to 100 Common Room contacts named by id (c_…): adds them all to a segment, and/or adds or removes tags (l_…).
• commonroom_update_organizationsApplies one change to up to 100 Common Room organizations named by id (o_…): adds them all to a segment, and/or adds or removes tags (l_…).
• commonroom_delete_contactsPermanently deletes up to 100 Common Room contacts named by id (c_…), as deleting them in the app does, with their activity.
• commonroom_right_to_be_forgottenFiles a privacy erasure (GDPR or CCPA right to be forgotten) for an email address in Common Room.

Connect it

First connect Common Room on Dashboard → Connections, then add Memtro to your client once. The Common Room tools appear alongside the tools of everything else you have connected; nothing is configured per connector.

Who may use it

The key identifies the person, and the server offers that person the tools they may use everywhere else in Memtro. A shared Common Room connection is used by the teams an administrator granted it to, tool by tool, on the Permissions page; a personal connection is used by its owner alone, and its tools that act stay off until the owner allows them. See Teams and permissions and Connectors.

Questions

Is this an official Common Room MCP server?

No. It is Memtro's MCP server with Memtro's Common Room connector behind it: the connector reads Common Room through its API with the credentials you connect on Dashboard → Connections, and Common Room publishes nothing here. The same endpoint carries every other system you connect and Memtro's memory tools.

What does it cost?

Nothing on top of Memtro. One price per organisation by its number of users, from $50 a month for up to 10 users after a 7-day free trial, with every connector, the MCP server, jobs and memory included. You bring your own model keys.

Can it change anything in Common Room?

Only when you ask, and only what it has been granted: create a segment of contacts or organizations; rename a segment; add up to 100 named contacts to a segment, and add or remove their tags; add up to 100 named organizations to a segment, and add or remove their tags; delete up to 100 named contacts (permanent); file a right-to-be-forgotten erasure for an email address (irreversible). Every other tool reads, searches or lists. An administrator grants each acting tool by name per team, and a personal connection acts only after its owner allows it.

Which clients work?

Any MCP client that speaks Streamable HTTP: Claude Code, Cursor, Claude Desktop, OpenCode, Codex, Zed, Windsurf, Cline and the Anthropic and OpenAI SDKs. There is no local process to run; the server is remote and authenticated with your key.
