Resend
Sending email, domains and contacts.
Resend is in the runelay catalog under Work and content. Once it is connected, every agent that uses runelay can call its tools.
| Auth | OAuth |
| MCP URL | https://mcp.resend.com/mcp |
| Connection name | resend |
| Tool prefix | resend. |
Add it
- Open Connectors → Catalog in the runelay panel.
- Press + next to Resend.
- A new tab opens on Resend's sign-in page. Approve access and the tab closes on its own.
The connection is saved even if the sign-in tab does not open. Finish it later with Finish sign-in on the catalog row, or from the sign-ins queue at /connectors/reconnect. See OAuth window not opening.
Use it
Agents find Resend's tools with search_tools and run them with call_tool or execute. Tool names start with resend.. See MCP tools.
The tools come from Resend's MCP server and can change on their side, so this page does not list them. The connection page in the panel shows how many tools it exposes right now.
Without the catalog
The catalog entry is a remote MCP connection to https://mcp.resend.com/mcp. You can add the same URL as a custom connection under another name.
