概览

AI 生成的概览

托管的 NeverBounce 服务器,让助手验证邮箱地址、运行并查看批量验证任务,以及查询剩余额度。

可以做什么
  • 查询账户额度、用量与任务数量
  • 验证单个邮箱地址,返回结果、标记与拼写纠正建议
  • 列出并查看批量验证任务的状态、统计与退信预估
  • 分页读取或以 CSV 下载任务中每个地址的结果
  • 用最多 100 个地址创建批量任务,并在额度上限内启动
  • 管理本服务器自身的套餐:用量状态、升级链接、取消订阅
适用场景
适合在聊天客户端中清洗或校验邮箱列表、在触达前确认单个地址是否可投递,或跟踪 NeverBounce 批量任务的进度与退信预估。
运行要求
以 URL 方式添加的远程 MCP 端点;通过 OAuth 登录,登录页会要求填写 NeverBounce 凭据。客户端配置中不要放 API 密钥或 Authorization 头。需要 NeverBounce 账户;免费档每月 50 次工具调用。
安装前请注意
验证会消耗 NeverBounce 额度:单次验证消耗 1 个额度,启动任务按每个计费地址消耗 1 个额度且无法停止或撤销。创建与启动是分开的写入步骤,启动前请确认。服务器还提供带 Stripe 结账链接的付费套餐与取消订阅功能,付款前请核对。提交的邮箱地址会发送给 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.

无需输入参数。

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.

输入参数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.

输入参数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.

输入参数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.

输入参数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.

输入参数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.

输入参数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.
