}This one needs environment variables set before it will start:
AGENTISEND_API_KEY (Your AgentiSend API key. Read from the environment only, never passed as an argument, because process arguments are visible to every other process on the machine.), AGENTISEND_MCP_URL (The hosted endpoint this launcher proxies to. Defaults to https://api.agentisend.com/mcp.).
The author declared them in the registry entry; get the values from the project itself.
This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.
