## What it does

Layrcake exposes tools for finding people and companies, checking email deliverability, spotting buying signals, and gathering company details. It can also draft email sequences, add recipients, and retrieve replies. Some operations use prepaid credits, and tool results report the charge.

The hosted MCP server uses browser sign-in with OAuth 2.1 and PKCE. New accounts start with 300 credits and need no card. In Claude Code, connect it with `claude mcp add --transport http layrcake https://mcp.layrcake.dev/mcp`.

Campaign drafts do not send on their own. Sending, buying mail capacity, and replying in an existing thread require a signed-in person to approve the action in the console. Approval is required before any email goes out.
