# Invalid Bounce — how to use (mcp.ai)

Connect your Invalid Bounce account and use 1 tools for email straight from your AI agent. Connect with your own API key. Invalid Bounce verifies email addresses through a bulk verification API.

## Option A — via MCP (recommended)
Remote MCP endpoint (HTTP, streamable): `https://api.mcp.ai/p_invalid_bounce?ms=1787293500000`
Add it as a custom/remote MCP connector in your client (Claude, Cursor, VS Code…), then authenticate when prompted. Once connected, ask the agent to use the server's tools (e.g. `invalid_bounce_start_bulk_verification`).

## Option B — via direct REST API
Base URL: `https://api.mcp.ai/api/invalid_bounce`
Auth: `Authorization: Bearer sk_live_…` — create a workspace API key at https://mcp.ai/settings/api-keys
Discover endpoints: `GET https://api.mcp.ai/api/invalid_bounce/_endpoints`

### Endpoints
- `POST https://api.mcp.ai/api/invalid_bounce/start/bulk/verification` — Irreversibly start an asynchronous email-verification job using the connected account's verification quota. This action returns job acceptance and an ID, not per-email results.
  - body: { emails: string[] }

## Example prompts
- "What can I do in Invalid Bounce?"
