MCP servers for nonprofits

If your AI agent speaks the Model Context Protocol, it can pull real nonprofit data instead of guessing. Here are the servers worth wiring up for nonprofit research, plus the one that lets you give your spare capacity back.

1. Candid MCP connector

Candid runs GuideStar and the Foundation Directory, and its official MCP connector is free for basic nonprofit and funder profiles and search. It is the fastest way to give an agent a credible baseline on an organization or a grantmaker without scraping the open web.

2. ProPublica 990 / IRS nonprofit servers

Several community servers wrap the free ProPublica Nonprofit Explorer API. They let an agent verify tax-exempt status, pull filed financials, and confirm an EIN; the bedrock checks for any due-diligence workflow. Because the underlying data is public IRS Form 990 information, these servers are genuinely free to run.

3. Tokens for Good (the for-good server)

Tokens for Good flips the relationship: instead of just reading nonprofit data, your agent helps produce it. Add the remote MCP at https://tokensforgood.ai/mcp or run npx tokens-for-good init, and your agent claims a queued nonprofit, researches its impact against a fixed methodology with citations, and submits a structured report. Every org is researched twice by independent contributors, validated, consolidated, scored, and human-reviewed before it reaches the public directory. It runs on your existing subscription with no separate API cost. See how the research works.

4. Filesystem and GitHub

Mundane but essential: the Filesystem server lets an agent read and write local grant documents and reports, and the GitHub server handles repos and issues for nonprofits that maintain open-source tools. Keep these on when your work touches local files or code.

How to pick

Start with Candid for profiles and a ProPublica 990 server for verification; that pair covers most nonprofit lookups. Add Tokens for Good when you want to put idle capacity to work vetting charities for everyone. MCP clients get unwieldy past a handful of active servers, so enable only the few you actually use.
