Common questions
Everything you need to know about Cursor and Warm.
How do I add Warm to Cursor?
Create a .cursor/mcp.json file in your project root with the MCP server config. Set the command to "npx", args to ["-y", "@warmio/mcp", "--server"], and add your WARM_API_KEY from Settings → API Keys. Cursor will automatically discover the tools.
What financial data can Cursor access?
Cursor can access your accounts (balances, types, institutions), transactions (amounts, merchants, categories, dates), and financial state: snapshots, recurring payments, budgets, goals, financial health, liabilities, investment holdings, and category spending. AI chat history and household/sharing settings remain app-only.
Can Cursor modify my financial data?
No. The MCP server is strictly read-only. Cursor cannot modify, delete, or transfer any data. Your API key is scoped to only your accounts, and you can revoke it instantly from Settings.
Does this work with Cursor Agent?
Yes. The MCP tools work with both Cursor chat and Cursor Agent. You can ask financial questions while coding and get answers without switching context.
Can I use this in any project?
Yes. Add the .cursor/mcp.json config to any project, or create a global config. The MCP server is project-agnostic—it connects to your Warm account, not your code.
Is this feature free?
No, the MCP server and API access are exclusive to Warm Pro ($24.99/mo). Free and Plus tiers do not include API access.
