What it can do, and your data
Nine tools, each one you approve. Underridge connects to Claude as an MCP connector built by Greenridge Group. Claude can call the nine tools below, and asks your permission the first time each one runs. They act only on your own Underridge account.
- underwrite_deal: underwrite a deal from documents or a link you give it, or a US stock from its ticker, and return the verdict, figures and full package.
- get_underwrite_status: check whether an underwrite is still running or finished.
- list_deals: list the deals in your workspace.
- get_deal: open one deal's details and results.
- add_pipeline_deals: add one or more deals to your pipeline.
- add_task: create a task on a deal.
- list_tasks: list the tasks in your workspace.
- get_account: read the signed-in account and its credit balance.
- get_credits: read your remaining underwrite credits.
Your data. Claude sees only what you share in the chat and what these tools return from your account. Materials you ask Underridge to underwrite are processed to produce your package and sent to its AI provider (Anthropic) for that purpose only. Account and underwrite records are stored with Supabase. Underridge does not sell your data and does not use it for advertising. Full detail is in the Privacy Policy.
Revoking access. You can disconnect at any time. In Claude, open Settings, then Connectors, then Underridge, and remove it; that immediately ends all tool access. You can also revoke the connection in your Underridge account, or email executives@greenridgegroup.org to delete your account and its underwrites.
