Validate IRS status with Windsurf and the MCP Server

Cascade calls `verify_charity_status` to pull live Candid tax eligibility directly into your Windsurf editor. Cascade reads the raw IRS standing of any target organization without forcing you to leave your Windsurf session. Cascade then runs `get_charity_check_pdf` to write the official Candid compliance PDF copy directly to your Windsurf project directory. Cascade saves the Candid PDF straight to your active Windsurf workspace directory without you typing a single command.

Deep financial vetting using Cascade

Cascade uses `get_nonprofit_premier` to pull Candid financial metrics and balance sheets directly into your Windsurf editor. Cascade processes the raw Candid financial tables and flags any potential IRS compliance issues in your Windsurf sidebar. While analyzing the Candid financials, Cascade chains a call to `get_grant_details` to verify where the foundation funding actually goes. You get a clean breakdown of active Candid grants written directly to your Windsurf workspace log by the MCP Server.

Track donor diversity and news in Windsurf

Cascade triggers `get_demographics` to assess the leadership diversity of potential nonprofit partners inside your Windsurf workspace. Cascade maps out board representation and staff Candid demographic data directly inside your active Windsurf file. Cascade immediately follows up with `get_nonprofit_news` to pull the latest public filings and Candid social sector updates. You see recent Candid organizational shifts alongside the demographic metrics without switching your Windsurf window.
