Resend
Give the Sazabi agent tools to send transactional and broadcast emails and manage domains, contacts, and audiences.
About
This is an MCP connector that gives the Sazabi agent tools from Resend's hosted MCP server at https://mcp.resend.com/mcp. Sazabi stores your Resend API key securely and sends it as the Authorization: Bearer token to Resend's MCP endpoint. Once connected, the agent can send emails and manage domains, contacts, and audiences.
What the agent can do:
- Send transactional and broadcast emails
- Manage domains (create, verify, and update)
- Manage contacts and audiences
- Retrieve send and delivery status information
Prerequisites
- A Resend account
- A Resend API key (
re_...) from the Resend dashboard - A verified sending domain
Set up in the dashboard
Configure connectors in the dashboard under Settings > MCP connectors.
Open the connector
Find Resend in Settings > MCP connectors.
Add your key
Create or copy an API key from the Resend dashboard. Choose the key's permission to match what you want the agent to do: Sending access (send emails only, the safer choice) or Full access (also manage domains, contacts, and audiences). Sazabi stores it securely and sends it as the Authorization: Bearer token to Resend's MCP endpoint (https://mcp.resend.com/mcp).
Set up with the CLI
Resend authenticates with a Resend API key, and sazabi mcp-connectors connect only supports OAuth providers — so set up this connector in the dashboard first (above). Once it's connected, the Sazabi CLI can inspect and manage it (installed and authenticated — see sazabi mcp-connectors reference):
sazabi mcp-connectors list
sazabi mcp-connectors details <connection-id>Find the connection ID with sazabi mcp-connectors list. To rotate the stored credentials later, use sazabi mcp-connectors update-credentials <connection-id>.
Verify
Open the connector's connection page under Settings > MCP connectors and confirm Sazabi lists the tools it discovered. Then, in a thread, ask the agent to use one of those tools and confirm it runs. If no tools appear, confirm the key is correct and your sending domain is verified.
Troubleshooting
No tools discovered — Confirm the API key is valid and has not been revoked. Re-enter it from Settings > MCP connectors.
Connection shows needs attention — The authorization or key may have expired or been revoked; reconnect from Settings > MCP connectors.
