Available tools 9

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

bulk

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.

verify

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. Requires an API key. Returns {success, credits_used, result}.

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. Limited per IP. Returns {success, credits_used: 0, result}.

agent

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 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.

api

get_api_discovery

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

cancel

cancel_bulk_job

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

credit

get_credit_balance

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

submit

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, credits_reserved}.

BounceLayer Email Verification — questions

Answers built from our own checks of this server.

What can BounceLayer Email Verification do?

It exposes 9 tools, read directly from the server on our last check. Among them: cancel_bulk_job, create_agent_account, get_api_discovery, get_bulk_job, get_credit_balance, list_bulk_jobs and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is BounceLayer Email Verification mostly used for?

Its tools cluster around verify and bulk. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is BounceLayer Email Verification working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 455 ms. The bar chart above shows every period we have measured.

How do I connect BounceLayer Email Verification?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does BounceLayer Email Verification need an API key?

No. BounceLayer Email Verification completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is BounceLayer Email Verification?

It answers our handshake in 455 ms on average, which is faster than 27% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use BounceLayer Email Verification?

The npm package @bouncelayer/mcp was installed 15 times in the last week. Week over week that is -29%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
