DonorPerfect API and MCP server

DonorPerfect's XML API handles records through raw procedure calls and has no call to send a thank-you email. Sign in to DonorPerfect once in your own Cloud Browser, and your AI agent does the work there for you. The same tools work over MCP for agents and as a REST API for scripts.

DonorPerfect's own API leaves this out. So we run one for you.

    Paste the snippet for your client. The same server and key serve every app you connect, so you do this once.

For scripts: REST API

Every tool is an endpoint under /api/v1/donorperfect with its own method and path, such as POST /api/v1/donorperfect/donors/{donor_id}/gifts, with the same API key. Our open-source repo has ready scripts to start from.

REST API docs

What can the DonorPerfect API and MCP server do?

14 tools on your own DonorPerfect account. Agents call them as operations of the MCP tools donorperfect_read and donorperfect_write; scripts call each one at its own REST endpoint, with the same inputs and answers.

Questions

Does DonorPerfect have an API?

DonorPerfect has an XML API with read and write access to donors, gifts, pledges and contacts, and no official MCP server (checked 23 Oct 2026). Calls are raw procedure or SELECT requests, and an admin generates the key under Settings > User Management > API Self Service.

How do I get access?

Sign up free, open DonorPerfect under Integrations in the console and press Request access. Your free trial starts with your account, no card needed.

Is the MCP server different from the API?

No, only the way in. Cotlet builds each integration as a REST API and puts an MCP server on top, so both have the same 14 tools, the same inputs and answers, one API key and one price. AI agents such as Claude, ChatGPT or Cursor use MCP; scripts, cron jobs and HTTP steps in n8n, Make or Zapier use the REST API.

What is the Cloud Browser?

Your own Chrome that Cotlet runs for you in the EU, around the clock. You open it from the console, sign in to DonorPerfect yourself and press Enable for agents. Your agent's calls go through it, from its IP with its cookies, so DonorPerfect sees the browser you signed in with. Password saving is off and the profile is stored encrypted with AES-256-GCM.

Can my agent act without asking me?

Not on anything that reaches other people: create_donor, update_donor, add_gift, create_pledge, apply_pledge_payment, send_thank_you_email wait for your OK by default. You can switch that off per tool for scheduled runs.

Do I need a DonorPerfect API key for Cotlet?

No. Cotlet works in your own DonorPerfect login and does not use the XML API. DonorPerfect generates API keys under Settings > User Management > API Self Service, and Cotlet needs none. What your user can open in DonorPerfect still counts.

Can it print or merge thank-you letters?

No. DonorPerfect merges letter receipts in Microsoft Word with Instant Merge, which Cotlet does not run. send_thank_you_email sends the email for donors whose delivery preference is Email or Email and Letter, and list_receipts_due shows which donors get a letter.

What is not covered?

Tributes and notifications, Batch Gift Entry, soft credits, split gifts, SmartAction setup, reports and mail merge are not tools. Gifts are entered one at a time on the donor record. DonorPerfect can ask for multi-factor sign-in (release notes, Sep 2026); you complete that step yourself.

Should I use a DonorPerfect MCP server from GitHub instead?

Pick one if you want the code on your own computer and do not mind the upkeep: you install it, sign it in and fix it when DonorPerfect changes. Pick Cotlet if you want it hosted and kept working for you.

Can I use it in n8n, Make or Zapier?

Yes. Add https://cotlet.dev/mcp/v1 in n8n's MCP Client node, or call the REST endpoints from an HTTP step in Make or Zapier.

Who runs Cotlet?

Cotlet is run by Take Group, a Polish software company working since 2019. Take Group runs about 3,200 websites on its own systems and has its own DevOps team for infrastructure security. We built and used integrations like this inside the company for years before opening them as Cotlet.

Is Cotlet affiliated with DonorPerfect?

No. Cotlet is independent and not affiliated with DonorPerfect.
