Overview

AI-generated overview

BounceBan MCP lets an assistant check verification credits, verify single emails, and submit and read bulk email verification tasks.

What you can do
  • Read account credit balance and rate limits
  • Verify a single email address and read the status of an existing verification ID
  • Submit 1–1,000 emails for asynchronous bulk verification and read task progress
  • Page through stored bulk results, retained for 90 days
  • Check monthly tool-call usage and manage the subscription (upgrade, cancel, feature request)
When to use it
Useful when cleaning or validating email lists before outreach, or when an assistant needs to confirm whether an address is deliverable and to track bulk verification jobs without leaving the chat.
Requirements
Remote MCP endpoint added by URL only; sign-in happens through the server's OAuth login page using your own BounceBan credentials. No API key or Authorization header is added to the client config. A free plan allows 50 tool calls per month; paid plans raise the limit.
Before you install
Verification tools spend credits on every request, including repeats, and require confirm:true; bulk submission can consume many credits. Upgrade returns a Stripe Checkout payment link, and cancellation gives no refund for the current period. Email addresses you submit are sent to BounceBan's hosted service.

Installation

In SourceWeft

  1. Open BounceBan MCP by usefulapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

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/io.usefulapi%2Fbounceban/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.

Read the install guide the agent follows

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://bounceban.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http bounceban https://bounceban.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "bounceban": {      "url": "https://bounceban.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your BounceBan credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/bounceban/

Connect your own BounceBan credentials through the hosted sign-in page.

bounceban_account

Read BounceBan credits and rate limits

Read verification credit balance and account rate limits without starting verification. Limits and credit balance are shared across the account's API keys.

Takes no parameters.

bounceban_verify_email

Start BounceBan email verification

Verify 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 later. Never resubmit simply because it is still pending. Basic-only mode can return unknown with score -1 for catch-all/SEG-protected addresses.

Parametersemailrequiredconfirmdisable_catchall_verify

bounceban_single_status

Read a BounceBan single verification

Read 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 another verification.

Parametersidrequired

bounceban_create_bulk_verification

Create a BounceBan bulk verification

Submit 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 more risky results; robust waits longer. No callbacks or automatic polling are configured.

Parametersnameemailsrequiredconfirmgreylisting_bypassdisable_catchall_verify

bounceban_bulk_status

Read BounceBan bulk task progress

Read 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.

Parametersidrequired

bounceban_bulk_results

Read one page of BounceBan bulk results

Read 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-progress results. A pending response means wait and check the existing task later.

Parametersidrequiredstatecursor
