Resend MCP Integration for Cursor
Connect Resend to Cursor through the local KosmoKrator MCP gateway with scoped tools, credentials, and write policy.
Connect Resend to Cursor
Expose selected local integrations to Cursor through KosmoKrator without configuring each service as its own MCP server.
Create or update .cursor/mcp.json with a KosmoKrator stdio server entry. The gateway is local, scoped to this integration, and starts with
--write=deny so Cursor can inspect read-capable tools without receiving write access by default.
Resend MCP Config for Cursor
Use the same KosmoKrator install and integration credentials that power terminal and headless runs.

Expose only Resend instead of a broad multi-service tool list.
Reuse credentials already configured for the KosmoKrator CLI and Lua runtime.
Start read-only, then opt into ask or allow for trusted workspaces.
