What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

• verify_email

  Verify a single email's deliverability (syntax, DNS/MX, SMTP mailbox, disposable / role / catch-all detection, confidence score). Costs 1 credit for a billable result (valid/invalid/catch_all/disposable/do_not_mail), whether fresh or served from cache. `unknown` results are free.

• submit_bulk_verification

  Queue a list of emails for asynchronous verification. Reserves up to N credits (final charge settles on completion). Poll get_bulk_job for status and results. Optionally provide webhook_url for a completion callback. Requires an API key. Returns {job_id, status, total_emails, cre

• get_bulk_job

  Get the status, progress, and (when complete) results of a bulk job by its job_id. Requires an API key.

• list_bulk_jobs

  List your recent bulk verification jobs (paginated, newest first). Optionally filter by status. Requires an API key.

• cancel_bulk_job

  Cancel a pending or processing bulk job and release any reserved credits. Requires an API key.

• get_credit_balance

  Return your current credit balance and lifetime usage. Requires an API key.

• verify_email_demo

  Check one email WITHOUT an API key: format, common typos, throwaway domains, role and free-provider addresses, and whether the domain has mail servers (MX). It never contacts the mailbox, so a good address comes back "unknown", not "valid"; use verify_email for a real answer. Lim

• create_agent_account

  Get your own BounceLayer API key without a person signing up first. No API key needed. Returns an API key with a few free credits and a claim_url. Use the key in the 'X-API-Key' header (reconnect this MCP server with it). Give claim_url to the person you work for: when they open

• get_api_discovery

  Return BounceLayer's machine-readable discovery URLs (OpenAPI, docs, auth.md, well-known metadata). No API key required.
