概览

AI 生成的概览

Layrcake 是一个托管的 GTM（市场进入）MCP 服务器，让助手查找 B2B 线索与公司、验证邮箱、读取购买信号，并起草或发起外联活动。

可以做什么
  • 搜索与补全人物和公司：查找线索与公司、获取已验证的工作邮箱与档案、验证邮箱可送达性
  • 读取购买信号与调研：意向信号、公开社交帖子、基于官网的是非判断、公司调研、潜在客户画像
  • 起草与管理活动：创建序列、通过防重复导入添加收件人、审批后启动、读取分类后的回复、设置线索状态、在会话中回复
  • 开通发信能力：通过报价与人工审批配置已预热发信域名和邮箱
  • 查看账户状态：身份、积分余额与用量、任务与请求状态
适用场景
适用于销售、增长和招聘流程：希望助手完成 B2B 潜客挖掘、资格判断与信息补全，或基于单一预付积分余额起草并执行邮件外联。适合希望由智能体推进 GTM 工作、但所有花费积分或发送邮件的操作仍由人工审批的团队。
运行要求
远程 Streamable HTTP 端点 mcp.layrcake.dev，无需本地安装包或 API 密钥。需要 Layrcake 账户，通过浏览器 OAuth 2.1（PKCE 与动态客户端注册）登录。需能访问 MCP 端点、OAuth 授权服务器和浏览器控制台。新账户含 300 免费积分，无需绑卡。
安装前请注意
多数工具会针对实时数据源消耗预付积分，每个工具都会报告所扣积分。活动相关工具会修改工作区数据，将线索标记为不感兴趣会在整个工作区范围内屏蔽。发送邮件、购买发信容量和会话内回复都需要已登录的人工在返回的链接上审批。服务器为托管且闭源，工具调用会把查询与工作区数据发送给 Layrcake 及其数据提供方。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Layrcake，将其添加到工作区。
  2. 连接 所需的 凭据。它们会被私密存储，绝不会在公开页面上展示。
  3. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/dev.layrcake%2Flayrcake/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

其他 MCP 客户端

把它添加到你客户端的 mcpServers 配置中。 客户端会在首次连接时完成 OAuth 登录。

README

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.

Tools (22)

ToolWhat it doesBilling
find_leadsSearch 200M+ B2B contacts by title, location, industry, company size or domainper lead returned
find_companiesDiscover companies by hiring activity, technologies in use, or lookalikesper company
enrichA person's verified work email and profileon hit only
enrich_companyCompany profile, technologies, funding, relationshipsper dataset
verify_emailTwo-stage deliverability check incl. catch-all analysisper call
find_intentBuying signals for company domains: hiring, funding, news, job changes, techper signal-bearing company
find_postsPublic social posts across LinkedIn, X, Reddit, YouTube, TikTok and moreper relevant post
check_companiesAnswer a yes/no question about each company from its own website, with the quoted evidenceper company
research_companyDated recent moves for one company, with sources, ranked for your goalper call
prospect_pictureOne picture of a person, their company, or both: role, recent activity, signalsper call
setup_sendingProvision warmed sending domains and mailboxes (quote → human approval)credits, approved in console
create_campaignDraft a sequence with variables and recipients; drafts never sendfree
add_leadsAdd recipients to a draft campaign through the suppression-safe importerfree
launch_campaignPreview → human approval in console → real sendsfree
get_replies / get_replyRead inbound replies, classifiedfree
set_lead_statusRecord interest; not_interested suppresses workspace-widefree
reply_to_threadPreview → human approval → send an in-thread replyfree
get_me / get_usage / get_operation / get_requestIdentity, balance and usage, job and request statusfree

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.

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.
