Clerk MCP server

What the model can do

Clerk user management for one instance: users (name, primary email, banned or locked, created, last sign-in and last activity), a user's sessions and organisation memberships, organisations with member counts, an organisation's members and roles, and its invitations. Can ban, unban, lock or unlock a user, revoke a session, delete a user, add, re-role or remove an organisation member, and invite somebody to or withdraw an invitation from an organisation, each only when asked.

Acts, when you ask

These change something in Clerk. 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.

• clerk_ban_userBan a Clerk user.
• clerk_unban_userRemove the ban from a Clerk user so they can sign in again.
• clerk_lock_userLock a Clerk user: they cannot sign in until the lock expires (the duration is the instance's restriction setting) or somebody unlocks them.
• clerk_unlock_userLift the lock on a Clerk user so they can sign in again straight away.
• clerk_revoke_sessionRevoke one Clerk session (sess_…, from clerk_list_sessions).
• clerk_delete_userDelete a Clerk user.
• clerk_add_organization_memberAdd an existing Clerk user to an organisation with a role.
• clerk_update_organization_member_roleChange an organisation member's role in Clerk (e.g. org:member to org:admin), which changes what they can do there from their next request.
• clerk_remove_organization_memberRemove a member from a Clerk organisation.
• clerk_invite_to_organizationInvite somebody to a Clerk organisation with a role.
• clerk_revoke_organization_invitationRevoke a pending Clerk organisation invitation, so its link no longer works.

Connect it

First connect Clerk on Dashboard → Connections, then add Memtro to your client once. The Clerk 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 Clerk 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.

• › Which organisation invitations are still pending?
• › Make Dan Fletcher an admin of the Northwind organisation

Questions

Is this an official Clerk MCP server?

No. It is Memtro's MCP server with Memtro's Clerk connector behind it: the connector reads Clerk through its API with the credentials you connect on Dashboard → Connections, and Clerk 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 Clerk?

Only when you ask, and only what it has been granted: ban a user (signs them out everywhere, revokes their OAuth grants and stops them signing in); unban a user; lock a user's sign-in until the lock expires; unlock a user; revoke one of a user's sessions; delete a user (permanent); add an existing user to an organisation with a role; change an organisation member's role; remove a member from an organisation; invite somebody to an organisation (Clerk emails them a join link); revoke a pending organisation invitation. 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.
