# MCP

If your MCP client restricts outbound network access, add **`api.gerri.commonpaper.com`** to the domain allowlist.

Some Gerri MCP tools need the client to run **curl** requests against that host (for example, uploading a file with a minted `curl_command`). Without the domain on the allowlist, those requests are blocked even if the MCP server itself is connected.

## Cursor

Enterprise admins can allow remote MCP hosts from the Cursor dashboard. Add a **URL** entry for `https://api.gerri.commonpaper.com/mcp` (or `https://api.gerri.commonpaper.com/*`).

See [Cursor MCP Allowlist](https://prod.cursor.com/docs/mcp#mcp-allowlist).
