Bearer <api_key>. Obtain via the lqwd_register tool (the only auth-free tool); the returned api_key has the form `lqwd_<random>` and is used on all subsequent MCP requests.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Check your LQWD agent account profile. Returns your account tier, status, and registration date. Always free. Authenticate by sending the HTTP header `Authorization: Bearer <your_api_key>` on MCP requests (where <your_api_key> is the `lqwd_...` key returned by lqwd_register).
This tool takes no arguments.
The server marks this tool as destructive. Running it may delete or overwrite data on the server or in any account you connected with your headers.

}Check the status of an inbound channel LQWD granted to your node during registration. Returns the current state (pending, active, failed), funding txid (when confirmed), and balances. Only meaningful if you registered with pubkey+node_uri; agents without a channel grant will get a 'no active grant' response. Always free. Authenticate by sending the HTTP header `Authorization: Bearer <your_api_key>` on MCP requests (where <your_api_key> is the `lqwd_...` key returned by lqwd_register).

}Register a new AI agent account with LQWD. Returns an API key and, when you supply a Lightning node's pubkey + node_uri, a one-time inbound channel on mainnet as part of the tier-1 faucet grant. Always free; no authentication required — this tool is how you GET your API key. To receive an inbound channel from LQWD, pass `pubkey` AND `node_uri` together.
| Argument | Type | Description |
|---|---|---|
| name* | string | Agent name (1-100 characters). Choose a descriptive name for your agent. |
| pubkey | string | Optional. Your LND node's public key (66-char hex string). When provided alongside node_uri, LQWD opens a one-time inbound channel to your node as part of the tier-1 faucet grant. Omit if you don't run a Lightning node. |
| node_uri | string | Optional. Your node's public URI in the form `pubkey@host:port` (port 9735 must be publicly reachable). Required alongside pubkey. The response will include `channel_granted` and `next_steps.channel_status_url` so you can poll the async open. |
