BounceLayer
Check if an email address is real before you send, with a plain reason for each result.
Connects to BounceLayer's email verification API. Muse can verify single addresses, queue bulk lists, check job status, cancel jobs, and read credit balance. Main checks need an API key; a limited demo works without one.
Try asking Muse: "Check whether the email addresses on my customer list are deliverable before I send a newsletter."

Also use it in ChatGPT or Claude
BounceLayer is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
Add it to ChatGPT
- 1
Open ChatGPT settings
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
- 2
Turn on developer mode
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
- 3
Create the connector
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
- 4
Use it in a chat
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT

verify_emailVerify 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_verificationQueue 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, creget_bulk_jobGet the status, progress, and (when complete) results of a bulk job by its job_id. Requires an API key.list_bulk_jobsList your recent bulk verification jobs (paginated, newest first). Optionally filter by status. Requires an API key.cancel_bulk_jobCancel a pending or processing bulk job and release any reserved credits. Requires an API key.get_credit_balanceReturn your current credit balance and lifetime usage. Requires an API key.verify_email_demoCheck 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. Limcreate_agent_accountGet 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_discoveryReturn BounceLayer's machine-readable discovery URLs (OpenAPI, docs, auth.md, well-known metadata). No API key required.Recent checks
