概覽

AI 產生的概覽

Verifox 電子郵件驗證 MCP 伺服器，讓助理驗證信箱可否送達，並依姓名與公司網域尋找商務信箱，支援單筆與批次，會消耗 Fox Credits。

可以做什麼
  • 驗證單一信箱的語法、MX、SMTP、catch-all、一次性信箱、角色信箱與免費信箱屬性，並給出 0-100 評分
  • 批次驗證信箱清單，每個信箱回傳一筆結果
  • 依姓名與公司網域尋找某個人的商務信箱
  • 為最多 1000 位聯絡人批次尋找商務信箱
  • 查詢帳戶剩餘的 Fox Credit 餘額
  • 透過 jobId 輪詢耗時較久的驗證或尋找工作
適用情境
適合在寄送開發信前清理名單、確認信箱是否可送達，或依姓名與公司網域推測商務信箱。適用於業務、招募與行銷等需要在助理內完成信箱清理的情境。
執行需求
可使用託管的遠端端點並在 x-api-key 標頭中傳入金鑰，或使用 npm 套件 verifox-mcp 透過 npx 在本機執行，需要 Node.js 18 或更新版本。必須提供 Verifox API 金鑰（foxkey_...），本機以 VERIFOX_API_KEY 傳入，遠端以 x-api-key 標頭傳入。需要能連線至 Verifox API 的網路。
安裝前請注意
每次呼叫都會從 API 金鑰所屬帳戶扣除點數：每驗證一個信箱 1 點，每次尋找 10 點，README 說明即使命中 24 小時快取的結果仍照常計費。批次名單可能很快消耗大量點數，建議先用 get_credits 查看餘額。API 金鑰是可計費的機密，不要寫入共用設定或日誌。信箱地址與聯絡人姓名會傳送到 Verifox 的伺服器。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Email Verifier，將其新增到工作區。
  2. 連接 x-api-key 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/ai.verifox%2Femail-verifier/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。

README

Verifox MCP Server

[smithery badge]

MCP (Model Context Protocol) server that gives Claude and other AI assistants the Verifox API — verify email deliverability and find business emails, both single and in bulk.

Requires Node.js 18 or newer (the client runs it with npx).

Quick start (published package)

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json) or Claude Code MCP config — no install needed, npx fetches it:

json
{  "mcpServers": {    "verifox": {      "command": "npx",      "args": ["-y", "verifox-mcp"],      "env": {        "VERIFOX_API_KEY": "foxkey_your_key_here"      }    }  }}

Get a free API key (1,000 credits) at https://verifox.ai/dashboard/api. Restart Claude Desktop and ask it to "verify these emails".

Tools

ToolDoesCredits
verify_emailVerify ONE email — SMTP deliverability, catch-all, disposable, role, free + 0-100 score1 / email
verify_emailsBulk-verify a LIST (1–100,000 emails) — submits, waits, returns one result per email1 / email
find_emailFind ONE business email from name + company domain (best match or not_found)10 / find
find_emailsBulk-find emails for a LIST of up to 1,000 contacts (name + domain each)10 / contact
get_creditsCheck the account's remaining Fox Credit balancefree
get_jobPoll a long-running verify_emails / find_email / find_emails job for results—

Verify and find are async for large lists: the bulk tools wait ~55s inline, and hand back a jobId to finish via get_job if a job runs longer. Every verification costs 1 credit, including a repeat answered from the 24-hour result cache.

Usage examples

In Claude Desktop (or any MCP client), just ask:

  • "Is [email protected] deliverable?" → verify_email
  • "Verify these emails: [email protected], [email protected], [email protected]" → verify_emails
  • "Clean this lead list and keep only the safe addresses" → verify_emails
  • "Find the email for Patrick Collison at stripe.com" → find_email
  • "Find emails for these 20 people and their company domains" → find_emails
  • "How many Verifox credits do I have left?" → get_credits
  • "Check on that verification job" → get_job

Hosted remote endpoint

No local install: point a remote-capable MCP client at

https://mcp.verifox.ai/mcp

(streamable HTTP) and send your key in the x-api-key header.

Local development

Run straight from source with Bun (no build):

bash
bun install
json
{  "mcpServers": {    "verifox": {      "command": "bun",      "args": ["run", "/FULL/PATH/TO/verifox-mcp/src/index.ts"],      "env": {        "VERIFOX_API_URL": "https://api.verifox.ai",        "VERIFOX_API_KEY": "foxkey_your_key_here"      }    }  }}

VERIFOX_API_URL defaults to https://api.verifox.ai when unset. For local development against the API on port 8001, set it to http://localhost:8001. Restart your client and the tools appear in its tool list.

Remote (HTTP) mode

The same server also runs as a streamable-HTTP MCP endpoint (for Smithery, claude.ai connectors, and other remote MCP clients). Set MCP_TRANSPORT=http (or a PORT) and it listens on POST /mcp with a GET /health check:

bash
MCP_TRANSPORT=http PORT=8080 node dist/index.js# or: docker build -t verifox-mcp . && docker run -p 8080:8080 verifox-mcp

In HTTP mode the Verifox API key is read per request from the Authorization: Bearer <foxkey> header (also accepts x-api-key or ?api_key=) — so one hosted endpoint serves many users, each on their own credits.

Environment Variables

VariableDefaultDescription
VERIFOX_API_URLhttps://api.verifox.aiVerifox API base URL
VERIFOX_API_KEY(empty)Per-user API key (foxkey_*), sent as x-api-key

Generate a foxkey_* key from the Verifox dashboard (API Keys). The key authenticates every tool call and is the account whose Fox Credits are charged (verify costs 1 credit per email, find 10 per contact; get_credits is free).

輸入參數email必填proxy

verify_emails

Bulk-verify a LIST of email addresses. Submits the whole list, waits for completion, and returns one result per email (same fields as verify_email). Best for cleaning lead lists. Charges 1 Fox Credit per email. Large lists that don't finish quickly return a jobId to poll with get_job.

find_emails

Bulk-find business emails for a LIST of contacts (name + company domain each). Submits the list, waits for completion, and returns the found email per contact. Up to 1000 contacts. Charges 10 Fox Credits per contact. Large lists that don't finish quickly return a jobId to poll with get_job.

輸入參數waitcontacts必填

get_credits

Get the current Fox Credit balance for the Verifox account tied to the API key. Free — no credits charged. Use it to check remaining balance before a big verify/find run (verify = 1 credit/email, find = 10 credits/contact).

無需輸入參數。

get_job

Check an async job started by verify_emails, find_email, or find_emails. Returns results if finished, otherwise the current status. Use the type shown in the submitting tool's response.
