1Your Heropost link
In Heropost, open Home → Connect your AI tools → Cursor and press Copy. You get the ready-made snippet, with your link inside. The link is the key — no sign-in, no token.
2Where it goes in Cursor
- In the Cursor app, open Customize → MCPs and press New MCP Server. Cursor opens
~/.cursor/mcp.json. - Add the
heropostentry — keep any servers already in the file — and save:
{
"mcpServers": {
"heropost": {
"url": "https://mcp.heropost.io/mcp/hp_ag_…"
}
}
}
Once it’s saved, heropost moves to Connected on the MCPs page.
