And MCP makes the experience even better. With Aryn MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Aryn with - [OpenAI Agents SDK](https://composio.dev/toolkits/aryn/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/aryn/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/aryn/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/aryn/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/aryn/framework/openclaw) - [Hermes](https://composio.dev/toolkits/aryn/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/aryn/framework/cli) - [Google ADK](https://composio.dev/toolkits/aryn/framework/google-adk) - [LangChain](https://composio.dev/toolkits/aryn/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/aryn/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/aryn/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/aryn/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/aryn/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 Aryn to Codex ### How to install Aryn 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 Aryn MCP server, and what's possible with it? The Aryn MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Aryn account. It provides structured and secure access to your document sets and analytics tools, so your agent can perform actions like document parsing, data extraction, metadata management, and workflow monitoring on your behalf. - Automated document set management: Create, organize, and delete entire docsets to keep your unstructured documents sorted and accessible for further processing. - Advanced document retrieval: Retrieve individual documents or their binary content by ID, making it easy for your agent to access and analyze specific files. - Dynamic query planning: Generate logical query plans for complex data extraction or analytics tasks before executing them, giving you more transparency and control over document analysis workflows. - Metadata and usage insights: Fetch detailed metadata and usage statistics for any docset, so you can track document activity and storage at a glance. - Asynchronous task monitoring: List and monitor all outstanding or running async tasks, helping you keep tabs on document processing operations and system status in real time. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `ARYN_CREATE_DOCSET` | Create DocSet | Tool to create a new docset. use when you need to allocate a storage container before adding documents. | | `ARYN_CREATE_DOCSET` | Create DocSet | Tool to create a new docset. use when you need to allocate a storage container before adding documents. | | `ARYN_DELETE_DOCSET` | Delete DocSet | Tool to delete a docset and all its documents. use after confirming the docset id, when you need to permanently remove a docset and its contents. | | `ARYN_GENERATE_PLAN` | Generate plan | Tool to generate a query plan without executing it. use when you need to review the logical plan before running your query (e.g., "generate a plan for revenue breakdown by region"). | | `ARYN_GET_DOC_SET` | Get DocSet Metadata | Tool to retrieve metadata for a specific docset. use when you have the docset id and optionally need usage statistics. | | `ARYN_GET_DOCUMENT` | Get Document by ID | Tool to retrieve a document by id. use after both docset and document ids are available. | | `ARYN_GET_DOCUMENT_BINARY` | Get Document Binary | Tool to retrieve the binary content of a document by docset id and document id. | | `ARYN_LIST_ASYNC_TASKS` | List Async Tasks | Tool to list all outstanding asynchronous tasks for the account. use when you need to check pending or running tasks. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Aryn MCP server provides comprehensive access to Aryn operations through Composio. Once connected, you can perform all major Aryn actions directly from Codex using natural language commands. ## Complete Code None listed. ## Conclusion ### Conclusion You've successfully integrated Aryn with Codex using Composio's MCP server. Now you can interact with Aryn 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 Aryn 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 Aryn operations - Explore cross-app workflows by connecting more toolkits - Build automation scripts that leverage Codex's AI capabilities ## How to build Aryn MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/aryn/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/aryn/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/aryn/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/aryn/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/aryn/framework/openclaw) - [Hermes](https://composio.dev/toolkits/aryn/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/aryn/framework/cli) - [Google ADK](https://composio.dev/toolkits/aryn/framework/google-adk) - [LangChain](https://composio.dev/toolkits/aryn/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/aryn/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/aryn/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/aryn/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/aryn/framework/crew-ai) ## Related Toolkits - [Google Drive](https://composio.dev/toolkits/googledrive) - Google Drive is a cloud storage platform for uploading, sharing, and collaborating on files.

With a standalone Aryn MCP server, the agents and LLMs can only access a fixed set of Aryn tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Aryn 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 Aryn tools. ### Can I manage the permissions and scopes for Aryn while using Tool Router? Yes, absolutely. You can configure which Aryn 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 Aryn 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)
