Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Bouncer MCP or direct API to verify emails, check deliverability, validate lists, and manage results through natural language.
Bouncer is an email validation platform that verifies the authenticity of email addresses in real-time and batch. It helps boost deliverability and reduce bounce rates for your communications.
Type what you want done — sign in and watch it run live in the Tool Router playground.
Every Bouncer action and event your agent gets out of the box.

Give your team centralized access control across every framework with Composio’s MCP Gateway.
EXPLORE MCP GATEWAY0CodeKit is a utility API platform for AI, document, image, and data workflows. Use it to convert, validate, generate, store, and automate data without custom backend code.
Airtop is a cloud browser platform for AI-powered web automation. Use it to navigate sites, extract data, and run reusable browser workflows.
Apify MCP is the official MCP server for Apify's web scraping and browser automation platform. Use it to run actors, collect structured web data, and automate crawling workflows.
Apilio is a home automation platform that lets you connect and control smart devices from different brands. It helps you build flexible automations with complex conditions, schedules, and integrations.
Yes. Composio is SOC 2 Type II compliant and is built to keep your Bouncer connection and credentials secure. OAuth tokens and API keys are encrypted, and sensitive customer data is protected at rest and in transit.
Composio also undergoes independent security testing and continuously monitors its systems for security threats. You can review the latest reports and policies in the Composio Trust Center.
Built-in connectors usually give one AI access to a limited set of apps. Many people use Composio because it lets their AI connect to more apps than it normally supports, or connect to multiple accounts for the same app (e.g. connect Claude to multiple Bouncer accounts).
With Composio, you connect Bouncer once and then use it across different AI assistants without setting it up separately in each one. Connect your apps to Composio once, then connect Composio to whichever AI you use, whether that's Claude, ChatGPT, Hermes, or your own custom assistant.
Managed auth, hosted MCP servers, and every Bouncer tool your agent needs.Free to start.
