- What you can do
- Search and enrich people and companies: find leads and companies, get verified work emails and profiles, verify deliverability
- Read buying signals and research: intent signals, public social posts, website-based yes/no checks, company research, prospect summaries
- Draft and manage campaigns: create sequences, add recipients through a suppression-safe importer, launch after approval, read classified replies, set lead status, reply in thread
- Provision sending capacity: set up warmed sending domains and mailboxes via a quote and human approval
- Check account state: identity, credit balance and usage, job and request status
- When to use it
- Useful for sales, growth and recruiting workflows where an assistant should prospect, qualify and enrich B2B contacts, or draft and run email outreach from a single prepaid credit balance. It fits teams that want agent-driven go-to-market work but keep a human approving anything that spends credits or sends email.
- Requirements
- Remote Streamable HTTP endpoint at mcp.layrcake.dev; no local package or API key. Requires a Layrcake account signed in through browser-based OAuth 2.1 with PKCE and dynamic client registration. Network access to the MCP endpoint, the OAuth authorization server and the browser console. New accounts start with 300 free credits and no card.
Installation
In SourceWeft
- Open Layrcake in the dashboard and add it to a workspace.
- Connect the required credentials. They are stored privately and never shown on public pages.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/dev.layrcake%2Flayrcake/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Other MCP clients
Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

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
Tools (22)
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.
Connect
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: [email protected]
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.
