GoodStanding MCP

Lets an assistant check whether a US nonprofit's EIN appears on IRS auto-revocation or California charity delinquency and suspension lists.

What it does

GoodStanding exposes a single tool, lookup_nonprofit_status(ein), which reports whether a US nonprofit's EIN is on the IRS auto-revocation list or the California Registry of Charities delinquency and suspension lists. It returns revocation and reinstatement dates, whether the 15-month streamlined reinstatement window is still open, and whether AB 488 requires fundraising platforms to block donations. A clear result means the EIN is on none of the tracked lists, and each answer includes a checked receipt recording when the lookup ran, which lists it read, and what those lists cover.

When to use it

Useful when an assistant needs to verify a US nonprofit's tax-exempt standing before donating, granting, partnering, or listing an organization on a fundraising platform. It fits due-diligence and compliance checks that would otherwise require manually searching IRS and California registry lists.

Requirements

Runs as a local process over stdio, installed via the npm package goodstanding-mcp (for example with npx). No API key, signup, or environment variables are declared. It can optionally serve streamable HTTP on a local port. Node.js and network access to the underlying registry data are needed.
