Check if an email address is real before you send, with a plain-English reason for every result.
Verifies email addresses for deliverability — single checks, bulk jobs, and credit balance — with a plain-English reason for each result.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/com.bouncelayer%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Verify an email address
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. Requires an API key. Returns {success, credits_used, result}.
emailrequiredSubmit a bulk verification job
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, credits_reserved}.
emailsrequiredwebhook_urlGet a bulk job's status and results
Get the status, progress, and (when complete) results of a bulk job by its job_id. Requires an API key.
job_idrequiredList your bulk jobs
List your recent bulk verification jobs (paginated, newest first). Optionally filter by status. Requires an API key.
pagestatuspage_sizeCancel a bulk job
Cancel a pending or processing bulk job and release any reserved credits. Requires an API key.
job_idrequiredGet your credit balance
Return your current credit balance and lifetime usage. Requires an API key.
Takes no parameters.
Demo email validation (no API key)
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. Limited per IP. Returns {success, credits_used: 0, result}.
emailrequiredCreate an agent account and API key
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 it and set an email and password, the account becomes theirs and gets the full free monthly checks. The key and claim link are shown only once. Limited per network and site-wide.
labelGet BounceLayer discovery URLs
Return BounceLayer's machine-readable discovery URLs (OpenAPI, docs, auth.md, well-known metadata). No API key required.
Takes no parameters.
75% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
Declare a GitHub repository with a README, or serve resource_documentation in the OAuth protected-resource metadata.
Declare a license in the repository or the registry entry.
