Acts, when you ask

These change something in Ontraport. 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.

• ontraport_create_contactCreates one Ontraport contact.
• ontraport_update_contactChanges an Ontraport contact's email, name, company, title or owner; fields left out stay as they are.
• ontraport_delete_contactPermanently deletes one Ontraport contact by id, with its history.
• ontraport_tag_contactsAdds up to 10 tags (ids from ontraport_list_tags) to up to 50 named contacts.
• ontraport_untag_contactsRemoves up to 10 tags from up to 50 named contacts.
• ontraport_create_tagCreates a contact tag in Ontraport (names are unique per object type).
• ontraport_add_to_sequenceAdds up to 50 named contacts to up to 10 Ontraport sequences (ids from ontraport_list_sequences).
• ontraport_remove_from_sequenceRemoves up to 50 named contacts from up to 10 Ontraport sequences; no further steps go to them from those sequences.
• ontraport_send_messageSends a saved Ontraport email (id from ontraport_list_messages, type e-mail) to up to 50 named contacts.
• ontraport_update_taskChanges one Ontraport task: mark it complete, cancelled or pending, move its due date, or hand it to another user (owner id).

Connect it

First connect Ontraport on Dashboard → Connections, then add Memtro to your client once. The Ontraport 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 Ontraport 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 Ontraport MCP server?

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

Only when you ask, and only what it has been granted: create a contact (refused when the email already exists); update a contact's name, company, title or owner; delete a contact; tag named contacts; remove a tag from named contacts; create a tag; add named contacts to a sequence; remove named contacts from a sequence; send a saved email to named contacts; complete, cancel, reschedule or reassign a task. 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.
