Connect it

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

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

Only when you ask, and only what it has been granted: add a note to a constituent; log an interaction (a call, meeting or letter) on a constituent; create a task for a Bloomerang user, with email notification off; add a constituent (individual or organisation); change a constituent's name, status, job title, employer or website; delete a constituent; record a cash, cheque or in-kind gift; refund a gift; complete a task; change a task's subject, due date, assignee or note; edit a note; edit an interaction; add an email address, phone number or postal address to a constituent; change a constituent's communication restrictions, preferred channel or email interests; create a fund or a campaign. 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.
