Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how IRS 990 Nonprofit Data holds up.
Operated by IRS 990 Nonprofit Data (olyport.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If IRS 990 Nonprofit Data adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose IRS 990 Nonprofit Data in the gate directory. No sign-in needed.
IRS 990 Nonprofit Data's tools are live in every AI client you've connected — with rules and logging built in.
