# Guardian > Compliance copilot for nonresidents, STEM OPT / H-1B workers, international students, and foreign-owned US entities. Guardian cross-checks immigration and tax documents to surface mismatches, missing forms, and deadline risks before USCIS or the IRS does. Guardian runs as a web app at guardiancompliance.app and as 23 MCP tools inside Claude Code, Claude Desktop, and Codex. It also exposes chat-based access through OpenClaw (WhatsApp, Telegram, Discord, Slack). Users upload documents to a personal data room; Guardian classifies, indexes, and validates them against template packages (H-1B petition, CPA tax engagement, more coming). Results are shareable with lawyers or CPAs via tokenized read-only links. ## Install - [For AI agents — install instructions](https://guardiancompliance.app/AGENTS.md): deterministic steps for Claude Code / Codex / Cursor to self-configure the MCP server.
