Common questions
Everything you need to know about Zed and Warm.
How do I add Warm to Zed?
Open Zed settings (Cmd/Ctrl + ,) and add the MCP server config under the "mcp" section. Set the command to "npx", args to ["-y", "@warmio/mcp", "--server"], and add your WARM_API_KEY. Zed will automatically discover the tools.
What financial data can Zed access?
Zed can access your accounts (balances, types, institutions), transactions (amounts, merchants, categories, dates), and your financial state bundle: snapshots, recurring payments, budgets, goals, and financial health. AI chat history remains app-only.
Can Zed modify my financial data?
No. The MCP server is strictly read-only. Zed 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 Zed's AI assistant?
Yes. The MCP tools integrate with Zed's built-in AI assistant. You can ask financial questions while coding and get answers without switching context.
Why Zed for financial queries?
Zed is built for speed. If you're already using Zed for its performance, having instant access to your financial data without leaving the editor keeps you in flow.
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.
