Cursor - SEAOTTER

Prefer seaotter.dev/connect — Add to Cursor opens a one-click install deeplink with your key filled in.

One-click (recommended)

Open seaotter.dev/connect while signed in.
Click Add to Cursor.
Approve the install in Cursor.

You’re done when SEAOTTER appears under MCP servers. Then paste:

Use the SEAOTTER MCP to onboard a Hermes agent named my-hermes, then talk to it.

Manual `.cursor/mcp.json`

If the deeplink didn’t open, create or edit .cursor/mcp.json (project or global):

{
  "mcpServers": {
    "seaotter": {
      "command": "npx",
      "args": ["-y", "@ryanseaotter/mcp-server"],
      "env": {
        "SEAOTTER_API_KEY": "so_…"
      }
    }
  }
}

Reload MCP after changing SEAOTTER_API_KEY: Cursor Settings → MCP → toggle seaotter off/on, or Command Palette → Developer: Reload Window. You do not need to restart Cursor to pick up a rotated Hermes runtime key — talk_to_hermes_agent refreshes that automatically.

Notes

Package on npm: @ryanseaotter/mcp-server (official SEAOTTER MCP).
Keep SEAOTTER_API_KEY out of git — use Cursor’s env field or a local config.
Optional: SEAOTTER_API for a non-production control plane.
See Connect from chat for the full flow.
