## Why nonprofit_lookup_ein is rated Low

This is a read-only query against publicly available IRS Exempt Organizations Business Master File data. It retrieves and returns information about non-profit organizations but does not create, modify, delete, or execute any actions. The data returned (name, address, subsection, status) are public records. No side effects or irreversible changes are possible.

From the tool's own definition: "Tool performs lookup of organization data: 'Look up a US tax-exempt organization by exact EIN' and 'Returns name, address, IRC subsection, and current EO status.' No modification, deletion, or execution capabilities are described."

## Use case
