Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
bounceban_accountRead verification credit balance and account rate limits without starting verification. Limits and credit balance are shared across the account's API keys.
bounceban_verify_emailVerify one email in regular mode. Costs verification credits on each request, including repeats, and requires confirm:true. Uses the standard API's 15-second result window; returns a final result or a queue/verifying task ID. Read that existing ID with bounceban_single_status lat
bounceban_single_statusRead an existing single verification ID without spending verification credits. Returns success, verifying or queue. Honor try_again_at when provided; poll no more than 10 times for an ID within 5 minutes, then stop. Results remain available for 90 days. This tool never starts ano
bounceban_create_bulk_verificationSubmit 1–1,000 emails for regular-mode asynchronous verification. Starts a task and can consume verification credits; requires confirm:true. Check the dashboard before resubmitting after a lost/invalid response. greylisting_bypass:auto balances speed and accuracy; speed may yield
bounceban_bulk_statusRead progress and aggregate results of an existing bulk task. Does not start verification. Wait between polls and honor account rate limits. importing/verifying status is still pending; finished means the task has ended.
bounceban_bulk_resultsRead up to 100 existing email results and a cursor for the next page. Results are retained for 90 days. No verification is started and no following page is fetched automatically. Omit state to get all processed results while a task is running; filtering by state can omit in-progr

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.6.4) reached the registry today.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
