What you can do with Bloomerang in Claude and ChatGPT
For fundraisers and donor-care staff who keep donors and gifts in Bloomerang.
Find a donor and review their giving history
The AI searches constituents by name or email, opens the profile and reads the timeline of gifts, interactions, notes and tasks.
List gifts by fund, campaign or appeal
The AI lists transactions (donations, pledges, recurring gifts) filtered by constituent, amount range or type, with the fund, campaign and appeal of each.
See which tasks are due and who has them
The AI lists tasks filtered by status, due-date range, assignee or constituent. You get the follow-ups to do first.
Review past interactions and notes
The AI lists interactions (calls, emails, meetings, letters) by constituent, channel or purpose, and the notes on a record.
Log an interaction or note, or add a task
The AI logs a call, email or meeting, adds a note to a constituent's record, or creates a follow-up task assigned to a user.
Changes dataAdd or update a constituent
The AI searches first to avoid a duplicate, then creates an individual or organization, or updates names, job, status, address, email or phone.
Changes dataHow do I connect Bloomerang?
Before you connect
The login page asks for your Bloomerang private API key.
In Bloomerang, click your User icon → Edit My User and generate a private API key (only an Administrator User can). The key carries that user's full privileges; it is used only to call the Bloomerang API on your behalf and to derive a private account id, and is never shown to anyone.

- Open Customize → Connectors, then click + Add → Add custom connector.
- Enter the name Bloomerang and this URL, then click Add:https://
bloomerang. usefulapi. io/ mcp - Claude opens the login page: enter your Bloomerang private API key.
- In a chat, click + → Connectors and turn on Bloomerang.
Team and Enterprise: an Owner adds the connector for the organization first.

Claude Code
Run this command, then run /mcp in Claude Code to log in:
Cursor
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"bloomerang": {
"url": "https://bloomerang.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"bloomerang": {
"type": "http",
"url": "https://bloomerang.usefulapi.io/mcp"
}
}
} Codex
Run these commands. The second one opens the login page:
Other clients
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Bloomerang private API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
Pricing
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per user | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this Bloomerang server only. Ask your AI to run bloomerang_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with bloomerang_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with bloomerang_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4
- Usage status (free-tier meter)
bloomerang_usage_statusReport the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter. - Request a missing feature
bloomerang_request_featureTell usefulapi that the user needs something the Bloomerang tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. - Upgrade to Pro or Pro+
bloomerang_upgradeGet a paid plan for Bloomerang (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter. - Cancel the Pro subscription
bloomerang_cancel_subscriptionCancel the caller's Bloomerang Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run bloomerang_upgrade later to undo the cancel before the period ends. Does not count against the meter.
FAQ
What can I do with Bloomerang in Claude or ChatGPT?
Find a donor and review their giving history. List gifts by fund, campaign or appeal. See which tasks are due and who has them. Review past interactions and notes. Log an interaction or note, or add a task. Add or update a constituent. See what you can do for the details.
Is this an official Bloomerang product?
No. usefulapi is an independent service. It is not affiliated with or endorsed by Bloomerang. The server calls the Bloomerang API with your own Bloomerang access, so it sees only the data that your account can see.
Can I connect Bloomerang to Claude or ChatGPT?
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
What do I need to connect?
The login page asks for your Bloomerang private API key. See Before you connect for where to find it.
Do I put my Bloomerang key or an Authorization header in the client config?
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Bloomerang private API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
How do you keep my Bloomerang credentials?
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Bloomerang API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Bloomerang.
Can the AI change my Bloomerang data?
Yes, if you approve it. 5 of the 20 Bloomerang tools can create or change data. The other 15 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
What does it cost?
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Bloomerang server only. Cancel any time: your paid plan then runs to the end of the paid period. Run bloomerang_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run bloomerang_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run bloomerang_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a Bloomerang tool that I need is missing?
Tell the AI what you wanted to do. It can send the request with bloomerang_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Which AI clients can I use?
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
