How it signs in
Through your browser, the first time a session uses it. The server answers with a sign-in challenge, OHarness discovers Resend’s authorization server and registers itself there on the spot, and the tokens land in ~/.oharness/auth.json, readable only by you. Nothing to paste, and nothing stored by us.
Try it
Once Resend is connected, a first prompt to see it work:

Adding it
- Download OHarness for the Mac, or install the CLI anywhere Node runs.
- In the composer, open the + menu and find Resend under Connectors or Plugins.
- Pick it and sign in when the browser opens. Its tools are available from the next turn.

Common questions
Does OHarness work with Resend?
Yes. Resend ships in OHarness as both an MCP connector and a plugin, so it is in the menu on first launch with nothing to look up.
How does the Resend connector sign in?
Through your browser. The first request is answered with a sign-in challenge, OHarness registers itself with Resend's authorization server on the spot, and the tokens are kept on your machine in auth.json, readable only by you. There is no key to paste.
What does the Resend plugin install?
5 skills and 1 MCP server. It is installed from resend/resend-skills at commit fd14937, the exact version OHarness was checked against, rather than whatever is on a branch today.
Is OHarness affiliated with Resend?
No. OHarness works with Resend through its public MCP server; Resend and its logo belong to Resend.
