Connect Hermes to Mercury
Set up in minutes
Choose where it runs
On your computer through your own Hermes, or hosted in the cloud. The rest of setup adapts to your choice:
Pick what it can do in Mercury
A preset of real Mercury operations. Each one becomes a tool the agent can call, and it can't touch anything outside the list.
Connect Mercury
One sign-in. The agent acts through your account, scoped to the operations you picked.
Add your personal MCP link
The last step mints a private MCP URL for this agent and walks you through exactly this, with your real link filled in. The page flips to Connected the moment your Hermes first calls in. Hermes connects when it next starts a session.
1. Run this in your terminal
2. Answer no when asked if the server requires authentication — the link itself is the key
<your-link> is your personal server URL — setup mints it for you.
