Connect Hermes to Tandem

Hermes Agent connects over OAuth. The first time it runs, it opens a browser for you to sign in.

Steps

1. Add Tandem to Hermes's config file, then start Hermes.

~/.hermes/config.yaml

mcp_servers:
  tandem:
    url: "https://api.tandemcrm.app/mcp"
    auth: oauth

How it signs in

Hermes signs in with OAuth: it registers itself with Tandem, opens your browser, and you sign in, choose a workspace and approve what it may do (read, suggest, write, delete). It gets crm:read and crm:write unless you approve less. Disconnect it any time under Agents in Tandem.

Try it

Ask Hermes: "Which Tandem workspace are you connected to, and what can you do there?" Then try "Add acme.com to Tandem with the details from its website."

See the tools reference for everything Hermes can do, and permissions for what each scope allows.
