Layrcake gives you go-to-market tools over MCP: find companies and people, verify and enrich emails, read buying signals, draft and launch campaigns and read replies. 22 tools behind one account. If you are Claude Code, follow the four steps below. If you are Claude in the chat app, or ChatGPT, go to the last section: you cannot add Layrcake yourself, but you can walk the user through it. 1. Register the MCP server. Run: claude mcp add --transport http --scope user layrcake https://mcp.layrcake.dev/mcp Do not add an Authorization header. Layrcake signs in with OAuth, and Claude Code opens the sign-in itself. 2. Sign in. Ask the user to type /mcp, choose layrcake and choose Authenticate. A browser window opens where they create a free account (300 credits, no card) or sign in, then approve the connection. If layrcake is not listed in /mcp, ask them to restart Claude Code and type /mcp again. Never create the account, type an email or code, or approve on their behalf. 3. Verify before you continue. Run claude mcp list and check that layrcake is connected. If it is not, stop and tell the user what failed. Do not carry on as if the tools were there. 4. First run. Call get_usage and tell the user their credit balance. If the layrcake tools are not available to you yet, ask the user to restart Claude Code; their sign-in is kept. Then offer: "Find 10 heads of sales at Series A SaaS companies in London and verify their emails."
