Chariot MCP Server

The Chariot MCP Server is a Model Context Protocol (MCP) connector that enables AI assistants like Claude to help you research nonprofits and charitable organizations. With access to Chariot's database of verified nonprofits, you can look up EINs, financials, DAF eligibility, IRS status, leadership, and more — all through natural conversation.

Typical conversation flow

Here's an example of how you might use the connector:

You: "Show me all unprocessed checks in our lockbox mail."

Claude: (Uses Chariot - list_mail) "Here are the unread mail items in your lockbox:

1. Check from Smith Foundation — $10,000, received July 18

2. Check from Anonymous Donor — $500, received July 19

3. Check from Jane Doe — $250, received July 20

Would you like to resolve any of these or create donation records from them?"

You: "Resolve the check from the Smith Foundation and log it as a donation to our Capital Campaign."

Claude: (Uses Chariot - create_donation, resolve_mail_item) "Done. I've created a $10,000 donation record designated to your Capital Campaign and marked the Smith Foundation mail item as resolved. Would you like to assign any custom properties to this donation?"

Troubleshooting

"I'm being asked to sign in every time"

• This may occur if your OAuth session has expired. Sign in again to re-authorize Claude.

• Check that your browser allows cookies and popups for Claude.ai, as these are required for OAuth.

"Claude can't find my donations"

• If your organization uses both a sandbox and production environment, confirm which environment Claude is connected to.

"Permission denied" or "Unauthorized" errors"

• Try disconnecting and reconnecting the Chariot connector in Claude.

"Donation was created with incorrect data"
