And MCP makes the experience even better. With Listclean MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Listclean with - [OpenAI Agents SDK](https://composio.dev/toolkits/listclean/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/listclean/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/listclean/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/listclean/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/listclean/framework/openclaw) - [Hermes](https://composio.dev/toolkits/listclean/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/listclean/framework/cli) - [Google ADK](https://composio.dev/toolkits/listclean/framework/google-adk) - [LangChain](https://composio.dev/toolkits/listclean/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/listclean/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/listclean/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/listclean/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/listclean/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 1000+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need. ## Connect Listclean to Codex ### How to install Listclean 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 Listclean MCP server, and what's possible with it? The Listclean MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Listclean account. It provides structured and secure access to your email verification tools, so your agent can perform actions like verifying emails, managing bulk verification lists, checking credits, and retrieving account info on your behalf. - Single email verification: Instantly check if an email address is valid, deliverable, or disposable—perfect for real-time signups or contact forms. - Bulk email list processing: Have your agent generate and upload CSV files of email addresses for large-scale verification and list cleaning. - Account credit monitoring: Easily monitor your remaining verification credits so your automations never hit a surprise limit. - Profile data retrieval: Let your agent fetch and review your Listclean account profile details for audits or reporting purposes. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `LISTCLEAN_CREATE_BULK_VERIFICATION_LIST` | Create Bulk Verification List | Tool to create a CSV file with provided email addresses for bulk verification.

With a standalone Listclean MCP server, the agents and LLMs can only access a fixed set of Listclean tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Listclean 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 Listclean tools. ### Can I manage the permissions and scopes for Listclean while using Tool Router? Yes, absolutely. You can configure which Listclean 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 Listclean data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
