ClickSend MCP server

What the model can do

ClickSend SMS: account balance, sent SMS history with delivery status, SMS campaigns, SMS templates, contact lists and their contacts. Can send an SMS to given numbers, send or schedule an SMS campaign to a list, cancel a scheduled SMS or campaign, create, update or delete an SMS template, create or delete a contact list, and add or remove a contact.

Acts, when you ask

These change something in ClickSend. 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.

Connect it

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

Ask it like this

• › Did yesterday's reminder texts go out?
• › What is our ClickSend balance?
• › Who is on the Clinic reminders list?
• › Which SMS campaigns went out this month?
• › Send the appointment reminder to the Clinic reminders list at 9am tomorrow

Questions

Is this an official ClickSend MCP server?

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

Only when you ask, and only what it has been granted: create a contact list; add a contact to a contact list (never overwriting an existing one); create an SMS template (nothing is sent); send an SMS to up to 10 given numbers, now or scheduled (spends credit); send or schedule an SMS campaign to every contact on a list (spends credit); cancel a scheduled SMS; cancel a scheduled SMS campaign; rename or reword an SMS template; delete an SMS template (permanent); remove a contact from a contact list (permanent); delete a contact list and its contacts (permanent). 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.
