This one needs environment variables set before it will start: SENDGRID_API_KEY (SendGrid API key (use a restricted key with Mail Send scope only)), SENDGRID_MCP_MODE (dry-run (default) or live), SENDGRID_MCP_RECIPIENT_ALLOWLIST (Comma-separated recipient addresses/domains allowed to receive mail), SENDGRID_MCP_WRITES_PER_HOUR (Hourly cap on write operations (sends)), SENDGRID_MCP_MAX_RECIPIENTS (Max recipients per send), SENDGRID_MCP_AUDIT_LOG (Path to the append-only audit log), SENDGRID_MCP_ALLOW_BCC (BCC stays disabled unless explicitly enabled). The author declared them in the registry entry; get the values from the project itself.
