And MCP makes the experience even better. With Clearout MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Clearout with - [OpenAI Agents SDK](https://composio.dev/toolkits/clearout/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/clearout/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/clearout/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/clearout/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/clearout/framework/openclaw) - [Hermes](https://composio.dev/toolkits/clearout/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/clearout/framework/cli) - [Google ADK](https://composio.dev/toolkits/clearout/framework/google-adk) - [LangChain](https://composio.dev/toolkits/clearout/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/clearout/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/clearout/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/clearout/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/clearout/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 Clearout to Codex ### How to install Clearout 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 Clearout MCP server, and what's possible with it? The Clearout MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Clearout account. It provides structured and secure access to email validation, prospecting, and enrichment tools, so your agent can perform actions like verifying email addresses, finding business contacts, checking domain details, and bulk-processing lists on your behalf. - AI-powered email verification: Instantly validate single or bulk email addresses to ensure deliverability and reduce bounce rates. - Email prospecting and enrichment: Find emails for people or companies, complete missing contact data, and verify if accounts are business or personal. - Domain and company intelligence: Retrieve company domains from names, fetch MX records, or pull WHOIS information to understand your leads and their infrastructure. - Disposable and catch-all detection: Check if an email is temporary or if a domain accepts all mail, helping you maintain list quality and avoid spam traps. - Bulk job automation: Upload, process, monitor, cancel, and download results for large-scale email finding and verification tasks, all through your agent. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `CLEAROUT_AUTOCOMPLETE_COMPANY_TO_DOMAIN` | Autocomplete Company to Domain | Tool to autocomplete company names to probable domains with confidence scores.

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