Kustomer MCP server

What the model can do

Kustomer customers, their conversations with messages and internal notes, conversation search by status, priority or date, and the org's sending accounts; can add an internal note, draft or send an email or SMS reply, open, close, snooze, assign, tag and delete conversations, and create, update and delete customers.

Acts, when you ask

These change something in Kustomer. 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.

• kustomer_add_conversation_noteAdds an internal note to a Kustomer conversation — context, what was checked, a hand-off.
• kustomer_create_customerCreates a customer in Kustomer with a name and optionally an email, tags and locale.
• kustomer_create_reply_draftSaves an unsent reply draft (email, SMS or chat) for a Kustomer customer, optionally in a conversation…
• kustomer_send_email_replySends a real email from one of the org's support addresses to a customer, threaded into their conversation when conversation_id is given.
• kustomer_send_sms_replySends a real text message from one of the org's SMS numbers to a customer's phone, in their conversation when conversation_id is given.
• kustomer_update_conversationChanges a Kustomer conversation by id: closes it (done), reopens it (open), snoozes it until a time, sets its priority (1 to 5) or name…
• kustomer_add_conversation_tagsAdds tags to a Kustomer conversation by name (a name that does not exist yet becomes a new tag), keeping its other tags.
• kustomer_remove_conversation_tagsRemoves the named tags from a Kustomer conversation, leaving its other tags.
• kustomer_create_conversationOpens a new Kustomer conversation for a customer, with a name (the subject agents see) and optionally a status, priority and assigned users or teams.
• kustomer_update_customerUpdates a Kustomer customer by id: name, emails, phones or locale.
• kustomer_delete_conversationPermanently deletes a Kustomer conversation by id, with its messages and notes; the API documents no restore.
• kustomer_delete_customerPermanently deletes a Kustomer customer record by id; the API documents no restore.

Connect it

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

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

Only when you ask, and only what it has been granted: add an internal note to a conversation; create a customer; save an unsent reply draft for an agent to review; send an email reply to a customer from a support address; send an SMS reply to a customer; close, reopen, snooze, prioritise, rename or assign a conversation; add tags to a conversation; remove tags from a conversation; open a new conversation for a customer; update a customer's name, emails, phones or locale; delete a conversation permanently; delete a customer permanently. 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.
