概覽

AI 產生的概覽

Layrcake 是託管的 GTM（進入市場）MCP 伺服器，讓助理尋找 B2B 潛在客戶與公司、驗證電子郵件、讀取購買訊號，並草擬或啟動外聯活動。

可以做什麼
  • 搜尋與補齊人物和公司：尋找潛在客戶與公司、取得已驗證的工作信箱與檔案、驗證信箱可送達性
  • 讀取購買訊號與研究：意向訊號、公開社群貼文、依官網內容做是非判斷、公司研究、潛在客戶概況
  • 草擬與管理活動：建立序列、透過防重複匯入加入收件人、審核後啟動、讀取分類後的回复、設定潛在客戶狀態、在討論串中回覆
  • 開通寄信能力：透過報價與人工審核設定已預熱的寄信網域與信箱
  • 查看帳戶狀態：身分、點數餘額與用量、任務與請求狀態
適用情境
適合業務、成長與招募流程：希望助理進行 B2B 潛客開發、資格判斷與資料補齊，或依單一預付點數餘額草擬並執行郵件外聯。適合想讓代理推動作業、但花費點數或寄送郵件仍由人工審核的團隊。
執行需求
遠端 Streamable HTTP 端點 mcp.layrcake.dev，不需本機套件或 API 金鑰。需要 Layrcake 帳戶，透過瀏覽器 OAuth 2.1（PKCE 與動態用戶端註冊）登入。需能連線 MCP 端點、OAuth 授權伺服器與瀏覽器主控台。新帳戶有 300 點免費額度，不需綁卡。
安裝前請注意
多數工具會對即時資料來源消耗預付點數，每個工具都會回報扣除的點數。活動相關工具會變更工作區資料，將潛在客戶標記為沒興趣會在工作區全域封鎖。寄送郵件、購買寄信容量與討論串回覆都需要已登入的人員在回傳的連結上審核。伺服器為託管且閉源，工具呼叫會把查詢與工作區資料傳送給 Layrcake 及其資料供應商。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Layrcake，將其新增到工作區。
  2. 連接 所需的 憑證。它們會被私密儲存，絕不會在公開頁面上展示。
  3. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/dev.layrcake%2Flayrcake/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

其他 MCP 客戶端

把它新增到你客戶端的 mcpServers 設定中。 客戶端會在首次連接時完成 OAuth 登入。

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.
