And MCP makes the experience even better. With Bouncer MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Bouncer with - [OpenAI Agents SDK](https://composio.dev/toolkits/bouncer/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/bouncer/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/bouncer/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/bouncer/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/bouncer/framework/openclaw) - [Hermes](https://composio.dev/toolkits/bouncer/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/bouncer/framework/cli) - [Google ADK](https://composio.dev/toolkits/bouncer/framework/google-adk) - [LangChain](https://composio.dev/toolkits/bouncer/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/bouncer/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/bouncer/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/bouncer/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/bouncer/framework/crew-ai) ## TL;DR ### Why use Composio? Apart from a managed and hosted MCP server, you will get: - CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool responses: Handle them to minimise context rot. - Dynamic just-in-time access to 20,000 tools across 870+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need. ## Connect Bouncer to Codex ### How to install Bouncer MCP in Codex ### Run the setup command Run this command in your terminal to add the Composio MCP server to Codex. ```bash codex mcp add composio --url https://connect.composio.dev/mcp ``` ## What is the Bouncer MCP server, and what's possible with it? The Bouncer MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Bouncer account. It provides structured and secure access to your email verification and validation tools, so your agent can perform actions like real-time email validation, bulk verification, domain checks, and toxicity analysis for improved email deliverability. - Real-time email verification: Instantly validate single email addresses to check deliverability and reduce bounce rates before sending messages. - Bulk batch verification: Initiate, manage, and retrieve results from batch email verification jobs to clean and maintain large email lists efficiently. - Toxicity analysis of email lists: Start and monitor toxicity analysis jobs to identify potentially harmful or problematic email addresses in your database. - Domain verification: Check the validity and configuration of email domains, including MX records and catch-all status, to ensure emails reach their intended targets. - Automated batch management: Finish, delete, or update batch verification and toxicity jobs to keep your verification workflows tidy and up-to-date. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `BOUNCER_CHECK_TOXICITY_LIST_JOB_STATUS` | Check Toxicity List Job Status | Tool to check the status of a specific toxicity list job. use after creating a toxicity list job to poll its status until completion. | | `BOUNCER_CREATE_BATCH_REQUEST` | Create Batch Request | Tool to initiate a batch email verification request. use when you have multiple emails to verify in one api call. returns a batch id and initial status. | | `BOUNCER_CREATE_TOXICITY_LIST_JOB` | Create Toxicity List Job | Tool to create a toxicity analysis job for a list of email addresses. use when you need to batch-process toxicity checks for multiple emails at once. | | `BOUNCER_DELETE_BATCH_REQUEST` | Delete batch request | Tool to delete a batch verification request. use when you need to remove all associated emails and results for a specific batch after confirming that the batch data is no longer required. | | `BOUNCER_DELETE_TOXICITY_LIST_JOB` | Delete Toxicity List Job | Tool to delete a specific toxicity list job. use when you need to remove a completed or unwanted toxicity analysis job after confirming its id. | | `BOUNCER_FINISH_BATCH` | Finish Batch | Tool to mark a batch verification process as finished. use after batch processing completes to stop further verifications and reclaim unused credits. | | `BOUNCER_GET_BATCH_RESULTS` | Get Batch Results | Tool to retrieve the results of a batch verification process. use after submitting a batch to fetch all processed email verification outcomes. | | `BOUNCER_VERIFY_DOMAIN` | Verify Domain | Tool to verify the validity and configuration of a domain. use when you need to confirm the domain's mx records and catch-all behavior. | | `BOUNCER_VERIFY_EMAIL` | Verify Email | Tool to verify a single email address in real-time. use when validating email entry form inputs instantly. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Bouncer MCP server provides comprehensive access to Bouncer operations through Composio. Once connected, you can perform all major Bouncer actions directly from Codex using natural language commands. ## Complete Code None listed. ## Conclusion ### Conclusion You've successfully integrated Bouncer with Codex using Composio's MCP server. Now you can interact with Bouncer directly from your terminal, VS Code, or the Codex App using natural language commands. Key benefits of this setup: - Seamless integration across CLI, VS Code, and standalone app - Natural language commands for Bouncer operations - Managed authentication through Composio - Access to 20,000+ tools across 870+ apps for cross-app workflows - CodeAct workbench for complex tool chaining Next steps: - Try asking Codex to perform various Bouncer operations - Explore cross-app workflows by connecting more toolkits - Build automation scripts that leverage Codex's AI capabilities ## How to build Bouncer MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/bouncer/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/bouncer/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/bouncer/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/bouncer/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/bouncer/framework/openclaw) - [Hermes](https://composio.dev/toolkits/bouncer/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/bouncer/framework/cli) - [Google ADK](https://composio.dev/toolkits/bouncer/framework/google-adk) - [LangChain](https://composio.dev/toolkits/bouncer/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/bouncer/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/bouncer/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/bouncer/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/bouncer/framework/crew-ai) ## Related Toolkits - [Apilio](https://composio.dev/toolkits/apilio) - Apilio is a home automation platform that lets you connect and control smart devices from different brands.

With a standalone Bouncer MCP server, the agents and LLMs can only access a fixed set of Bouncer tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Bouncer and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Codex? Yes, you can. Codex fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Bouncer tools. ### Can I manage the permissions and scopes for Bouncer while using Tool Router? Yes, absolutely. You can configure which Bouncer scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Bouncer data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) ยท [Composio docs](https://docs.composio.dev/llms.txt)
