Common questions

Is Layrcake safe?

It passed 1 of 1 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 14 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?

Layrcake MCP server

Layrcake is go-to-market infrastructure for AI agents: one MCP server and API that lets Claude, ChatGPT, Cursor and Codex find leads, verify emails, read buying signals and run approved campaigns, behind one prepaid credit balance.

Endpoint: https://mcp.layrcake.dev/mcp (Streamable HTTP)
Auth: OAuth 2.1 with dynamic client registration and PKCE. Sign in when your client prompts. Free to start: 300 credits, no card.
Docs: https://docs.layrcake.dev · Pricing: https://docs.layrcake.dev/pricing.html · Privacy: https://layrcake.dev/privacy

`launch_campaign`	Preview → human approval in console → real sends	free

Every tool returns the outcome and the credits it charged. Free reads run without prompting; tools that spend credits or change campaign data are annotated so hosts ask first; anything that sends email or buys capacity always needs a signed-in human to approve at a link the tool returns.

# Claude Code

claude mcp add --transport http layrcake https://mcp.layrcake.dev/mcp

{ "mcpServers": { "layrcake": { "type": "http", "url": "https://mcp.layrcake.dev/mcp" } } }

Also listed on the official MCP Registry as dev.layrcake/layrcake, Glama and Smithery.

This repository holds the listing manifest for directories; the server itself is hosted and closed source. Questions: founders@layrcake.dev

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.

License

Proprietary. Use of the hosted service is governed by Layrcake's terms and privacy policy.
