How do AI agents use Resend through Open Connector?

Your user connects Resend once with one of its cataloged authentication methods. Open Connector stores the credential in an encrypted vault and exposes Resend tools to your agent over MCP or a typed API, with credentials injected server-side on each call.

Is this a Resend MCP server?

Yes. Open Connector can serve Resend as a named MCP server with a scoped allowlist and a per-user connection URL, so any MCP client can call Resend actions with credentials injected server-side.

Where do Resend credentials live?

In your own infrastructure. Open Connector keeps credentials in its own vault and injects them at call time, so they never leave your environment.

Resend integration

Resend integration for AI agents.

Resend integration for AI agents with secure authentication and server-side credential injection. Open Connector runs the OAuth, seals the token in an encrypted vault, and serves Resend tools to your agent over MCP or a typed API — credentials injected server-side, every call audited, nothing leaving your infrastructure. Open source (AGPL-3.0) and self-hostable.

What your agents can do

Real Resend actions, managed and audited.

Your user connects Resend once; your agent can then use Resend API to send email, manage domains, contacts, audiences, broadcasts, webhooks, and API keys — scoped to the OAuth permissions you grant and the tool allowlist you configure. Every action is least-privilege and written to a tamper-evident audit trail.

1
Your user grants Resend access once (OAuth) — the token lands in the vault.
2
Your agent calls a tool over MCP or the typed API; Open Connector injects the credential server-side.
3
Every routed call appends a hash-chained audit record — nothing leaves your infra.

Tools & triggers

Supported Resend tools.

83 tools are generated from the published Resend catalog. Descriptions are plain text; each action remains subject to its configured authentication and tool allowlist.
