概覽

AI 產生的概覽

託管的 NeverBounce 伺服器,讓助理驗證電子郵件地址、執行並檢視批次驗證工作,以及查詢剩餘額度。

可以做什麼
  • 查詢帳戶額度、用量與工作數量
  • 驗證單一電子郵件地址,回傳結果、標記與拼字修正建議
  • 列出並檢視批次驗證工作的狀態、統計與退信預估
  • 分頁讀取或以 CSV 下載工作中每個地址的結果
  • 以最多 100 個地址建立批次工作,並在額度上限內啟動
  • 管理此伺服器本身的方案:用量狀態、升級連結、取消訂閱
適用情境
適合在聊天用戶端中清理或校驗電子郵件名單、在寄送前確認單一地址是否可投遞,或追蹤 NeverBounce 批次工作的進度與退信預估。
執行需求
以 URL 方式加入的遠端 MCP 端點;透過 OAuth 登入,登入頁會要求填寫 NeverBounce 憑證。用戶端設定中不要放 API 金鑰或 Authorization 標頭。需要 NeverBounce 帳戶;免費方案每月 50 次工具呼叫。
安裝前請注意
驗證會消耗 NeverBounce 額度:單次驗證消耗 1 個額度,啟動工作則依每個計費地址消耗 1 個額度,且無法停止或復原。建立與啟動是分開的寫入步驟,啟動前請先確認。伺服器另提供含 Stripe 結帳連結的付費方案與取消訂閱功能,付款前請先核對。送出的電子郵件地址會傳送給 NeverBounce。

README

NeverBounce MCP by usefulapi

Connect your NeverBounce account.

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://neverbounce.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http neverbounce https://neverbounce.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "neverbounce": {      "url": "https://neverbounce.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your NeverBounce credentials.

工具

neverbounce_get_account_info

Get account info and credits

Credits left (paid and free), credits used, and how many verification jobs are completed, queued, processing or under review. Free: it spends no credits. POST /account/info.

無需輸入參數。

neverbounce_verify_email

Verify one email address

WRITE: SPENDS 1 of your NeverBounce credits per call. Verifies ONE e-mail address and returns result (valid, invalid, disposable, catchall or unknown), flags (e.g. has_dns_mx, role_account, free_email_host), a suggested correction for typos like gmal.com, and optionally the parsed address parts. NeverBounce's usage rules: use this for a single address at the point of entry; do NOT call it in a loop over a list or database (the account can be locked) - use neverbounce_create_job for lists. POST /single/check.

輸入參數email必填timeoutaddress_info

neverbounce_list_jobs

List verification jobs

Bulk verification jobs of the account (most recent first as NeverBounce returns them) with id, status, filename, timestamps, totals per result (valid, invalid, catchall, disposable, unknown, duplicates, bad_syntax), bounce estimate and percent complete. Filter by id, exact filename or status. POST /jobs/search.

輸入參數pagejob_idfilenamejob_statusitems_per_page

neverbounce_get_job

Get job status

One verification job: status (waiting, parsing, running, complete, failed, under_review...), failure reason, timestamps, totals (records, billable = credits it will use, processed, valid, invalid, catchall, disposable, unknown, duplicates, bad_syntax), bounce estimate and percent complete. Poll this until status is complete. POST /jobs/status.

輸入參數job_id必填

neverbounce_get_job_results

Get job results (paged)

Per-address results of a job: the submitted row (data) and its verification (result, flags, suggested_correction, address info). Paged; use neverbounce_download_job_results for a CSV. The job must be complete. POST /jobs/results.

輸入參數pagejob_id必填items_per_page

neverbounce_download_job_results

Download job results as CSV

The results of a complete job as CSV text (the submitted columns plus email_status), cut at 200000 characters with a note when longer (use neverbounce_get_job_results to page through large jobs). By default every result type is included; set a type to false to leave it out. POST /jobs/download.

輸入參數job_id必填validsinvalidsunknownscatchallsdisposables

neverbounce_create_job

Create a bulk verification job

WRITE: creates a bulk verification job from up to 100 e-mail addresses given in this call, and has NeverBounce parse it. It does NOT start the verification and spends NO credits; run neverbounce_start_job afterwards (that spends 1 credit per billable address). Put ALL the addresses of one list into ONE job: NeverBounce's rules allow 10 concurrent jobs and 50 runs a day, and many small jobs in a short time can get the account locked. Returns the job_id. POST /jobs/create.

輸入參數emails必填filenameleverage_historical_data

neverbounce_start_job

Start a verification job

WRITE: STARTS a created job and SPENDS 1 credit per billable address (shown as total.billable in neverbounce_get_job); it cannot be stopped or undone. Safety: you must pass max_credits, and the job is refused when its billable count is above it or above 1000 (start bigger jobs in the NeverBounce dashboard). The job must be in status waiting or waiting_analyzed. With run_sample true it only runs the free sample analysis (estimated bounce rate) and spends nothing. POST /jobs/start.
