Claude
Add Marina as a connector once, and it is there in the browser, on desktop, and on your phone.
Claude reaches the hosted server over the network, so there is nothing to install and no token to mint.
https://mcp.marinahost.app/mcpAdding it
- Open Customize > Connectors.
- Click +, then Add custom connector.
- Paste the address above and click Add.
Claude sends you to Marina to sign in and approve what it may do, and its tools appear when you come back. What the screen asks for covers the access it requests and the four things it never gets.
Leave Advanced settings empty. The OAuth client ID and secret there are for servers that need a credential arranged with them beforehand. Ours identifies a client by the metadata that client publishes, so there is nothing to paste and nothing to keep secret.
On a team
Only an owner can add a connector for everyone. In Organization settings > Connectors, choose Add, hover Custom, and pick Web.
Everyone else then opens Customize > Connectors and clicks Connect to sign in as themselves. That part matters: each person approves their own access, so what Claude may do for them is bounded by their own role in your Marina account. A developer’s Claude cannot spend the wallet because a developer cannot.
Once, for everywhere
A connector added here is available in Claude Code too, with no second setup. Claude Code is worth reading anyway if you want the assistant confined to your own machine, or holding a credential you minted rather than access you granted in a browser.
What it costs you
Nothing on our side, and it works on every Claude plan. A free plan allows one custom connector, which is fine if Marina is the one.
Taking it back
Sign-in is access you granted, not a secret you handed over, so you withdraw it rather than rotate it. Remove the connector in Claude, or revoke it under Settings > Tokens in your Marina dashboard, where the access Claude holds is listed alongside anything else you have issued. Either way it stops the moment you do it.
