Custom Connectors

Solutions for nonprofits

How can a nonprofit give Claude read-write access to its systems?

Your donor data, fundraising history, supporter emails, and grant records live across a handful of tools. We build and maintain custom MCP connectors for each one, so Claude can read what is there and write back, with scoped permissions and the risky actions gated.

How can a nonprofit give Claude read-write access to its systems?

A nonprofit gives Claude read-write access through custom MCP connectors, small hosted servers that expose each system to Claude over the Model Context Protocol. We build one connector per tool, such as your donor CRM, email platform, and payment processor, each with read tools and scoped write tools so Claude can update records instead of you exporting spreadsheets.

Key takeaways

  • We build and host a connector for each system you use, so Claude works across your donor CRM, email, payments, and grant records in one conversation.
  • Each connector authenticates as a real account and inherits its permissions exactly, so Claude never sees or does more than the staff member behind it could.
  • Create and update flow freely. Deleting records, issuing refunds, and sending email blasts stay behind a confirmation step your team controls.
  • We work with whatever you run, including Salesforce Nonprofit Cloud, NPSP, and in-house donor databases that are not in Claude's connector directory.

What can Claude do across your donor and fundraising stack?

Claude can work across your donor and fundraising stack the way a staff member would: look up a donor in your CRM, check their giving in Stripe, draft a segmented Mailchimp appeal, and log the outreach back to the record. The connectors handle the reads and the writes, so the work stays in your systems.

  • Pull a lapsed-donor segment from your CRM, draft a re-engagement email, and update each constituent record with the campaign tag.
  • Reconcile online gifts by reading Stripe payouts against the donations logged in your donor database, flagging anything that does not match.
  • Prepare a board or grant report by combining program numbers from Google Sheets with giving totals from your CRM.
  • Keep a custom grants tracker current by updating deadlines, amounts, and status as reporting requirements come in.

How does authentication and donor data security work?

Authentication works by connecting as a real account in each system, using OAuth where the tool supports it or a scoped API key where it does not. The connector inherits that account's existing permissions and never grants Claude more access than the account already has. We handle token refresh, so connections stay live without anyone re-authenticating constantly.

That scoping matters most with supporter data. If a staff role cannot view major-donor records, restricted-fund details, or full payment history, neither can Claude through that connection. And the actions that carry real risk for a nonprofit, like deleting a constituent, issuing a refund, or sending an email to your whole list, stay behind a human-in-the-loop confirmation that your team approves before anything happens.

Which nonprofit tools can you connect?

The nonprofit tools we connect include Salesforce, the email platforms you send appeals through, the payment processors that handle online giving, the spreadsheets that hold program and grant data, and any in-house donor database. Each one gets its own custom connector, and Claude can use several of them in the same conversation.

Salesforce connector

Read and update constituent records, opportunities, and campaigns in Salesforce, including Nonprofit Cloud and NPSP objects like accounts, contacts, and gifts.

Mailchimp connector

Pull list and audience data, draft and update campaigns, and segment supporters. Actually sending a blast stays behind a confirmation you approve.

Stripe connector

Read donations, recurring gifts, and payout history for reconciliation. Refunds and other money-moving actions are gated behind a human-in-the-loop step.

Custom CRM or donor database connector

Connect an in-house donor database, a homegrown grants tracker, or a heavily modified CRM that is not in Claude's connector directory.

Google Sheets connector

Read and write the spreadsheets where program data, grant deadlines, and board reports actually live, so Claude can update them in place.

Frequently asked questions

How can a nonprofit give Claude read-write access to its systems?
A nonprofit gives Claude read-write access by adding custom MCP connectors that we build and host for each system you use, such as your donor CRM, email platform, payment processor, and grant records. Each connector exposes read tools and scoped write tools, so Claude can pull data and update records without anyone exporting spreadsheets by hand.
Is donor and supporter data safe with this setup?
The connector authenticates as a real account in your system and inherits exactly the permissions that account already has, never more. If a staff member cannot see major-donor records or financial reports, neither can Claude through that connection. We scope each connector to the objects and actions you approve, and destructive or outbound actions stay gated.
Can Claude actually update our donor records, or only read them?
Claude can update them. The connector exposes write tools, so Claude can create and update constituent records, log gifts, tag segments, and fill in custom fields. Create and update flow inside a conversation you start. Deleting a record, refunding a payment, or sending an email blast are gated behind a confirmation step your team controls.
We use Salesforce Nonprofit Cloud and a custom grants database. Do both work?
Yes. We build a connector for Salesforce that works with Nonprofit Cloud and NPSP objects, and a separate connector for an in-house or custom grants database that is not in Claude's connector directory. You can run several connectors at once, so Claude works across your donor CRM, payments, email, and grant tracking in one place.
Who maintains the connectors as our tools change?
We do. When Salesforce changes an object, your email platform updates its API, or your custom database adds fields, we update the connector so it keeps working. That ongoing maintenance is the difference between a one-off script that quietly breaks before your next appeal and a connector your team can rely on.
