Acts, when you ask

These change something in Givebutter. 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.

• givebutter_add_contact_noteAdds a note to a Givebutter contact's activity timeline.
• givebutter_add_contact_tagsAdds tags to a Givebutter contact, keeping the tags it already has; a tag that does not exist yet is created.

Connect it

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

• › How much has the Winter Appeal raised against its goal?

• › What did we raise last month, by currency?
• › Tag Dan Fletcher as a gala volunteer.
• › Record a £100 cash gift from Sarah Chen to the Winter Appeal, dated yesterday.

Questions

Is this an official Givebutter MCP server?

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

Only when you ask, and only what it has been granted: add a note to a contact's activity; add tags to a contact; remove tags from a contact; create a contact (matches an existing one by email or phone unless forced); edit a contact's name, details, notes or opt-ins; delete a contact (restorable in Givebutter); delete a note or activity from a contact (permanent); record an offline gift (cheque, cash and the like) against a campaign and contact; edit an offline gift's note, cheque number, fund, campaign, method or date; create a campaign; edit, publish or unpublish a campaign; delete a campaign that has raised nothing (permanent); remove a fundraiser from a campaign (permanent); add a ticket type to an event campaign; create a fund; create a household. 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.
