Common questions
Is Layrcake safe?
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 16 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

Grok Build
Open /marketplace in Grok Build, find Layrcake, and install it. On first connection, complete the Layrcake sign-in and consent flow in your browser; new accounts are free with 300 credits and no card. The plugin contains no API key or local executable.
Network access and permissions
https://mcp.layrcake.dev/mcp— Layrcake's hosted Streamable HTTP MCP endpoint. The same host serves OAuth discovery metadata at/.well-known/oauth-protected-resource.https://api.layrcake.dev— Layrcake's OAuth authorization server (dynamic client registration, token issuance, refresh), discovered from the MCP metadata.https://app.layrcake.dev— the browser sign-in and consent page, and the console where launches, replies and purchases are approved.
Authentication uses your Layrcake account through browser-based OAuth 2.1 with PKCE. Grok sends the resulting bearer token to the hosted server; the server scopes every tool to your workspace. Six tools are read-only (get_me, get_usage, get_operation, get_request, get_replies, get_reply). The other thirteen are annotated destructive: seven spend prepaid credits against live data providers, three change campaign data, and three (setup_sending, launch_campaign, reply_to_thread) only return a preview and an approval link — nothing is bought or sent until a signed-in human approves in the console. No token or credential is bundled with this plugin.
