This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Aryn account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## 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) - [Codex](https://composio.dev/toolkits/aryn/framework/codex) - [OpenClaw](https://composio.dev/toolkits/aryn/framework/openclaw) - [Hermes](https://composio.dev/toolkits/aryn/framework/hermes-agent) - [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) - [Pydantic AI](https://composio.dev/toolkits/aryn/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/aryn/framework/autogen) ## TL;DR ### How Atomic Agent connects to Aryn Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication. Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account. ## Connect Aryn to Atomic Agent ### Connect Aryn to Atomic Agent - Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key. - In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart. - Ask Atomic Agent to do something in Aryn. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Aryn account, then return to Atomic Agent to continue. ### Headless setup Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file. ```bash COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY ``` ## 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_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 by its ID. Use when you need to check DocSet details like name, creation time, properties, or prompts. | | `ARYN_GET_DOCUMENT` | Get Document by ID | Retrieve a document by ID from Aryn DocParse storage. Returns the document's parsed elements (text, tables, sections with embeddings), custom properties, and optionally the original binary content. Use this after obtaining a docset_id and doc_id from other Aryn actions (e.g., list_docs or add_doc). | | `ARYN_GET_DOCUMENT_BINARY` | Download Document Binary | Download the original binary content (e.g., PDF, image) of a document from an Aryn DocSet. This action retrieves the raw binary file that was originally uploaded to the DocSet. Use this when you need to access the original document file rather than the parsed elements or extracted text. | | `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. | | `ARYN_PARTITION_DOCUMENT` | Partition Document | Partition a document using Aryn DocParse to extract and structure its content elements including text, tables, and images. Supports file upload or URL input with extensive processing options for chunking, OCR, table extraction, image extraction, and multiple output formats. Use when you need to extract structured content from PDFs or other document formats. | | `ARYN_SUBMIT_ASYNC_ADD_DOC` | Submit Document for Async Add Doc | Tool to submit a document for asynchronous addition to a DocSet. Returns a task ID to track the operation. Use when you need to add documents to an existing DocSet and want to track the processing status. | ## Supported Triggers None listed. ## Troubleshooting ### Why is my API key rejected? Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying. ### Why are Composio tools unavailable after saving a key? Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk. ### Does Composio have a free plan? The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection. ## Complete Code None listed. ## Conclusion ### Use Aryn from Atomic Agent With your account connected, ask Atomic Agent to work with Aryn in natural language. You can connect more apps through the same Composio integration as you need them.

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 Atomic Agent? Yes, you can. Atomic Agent 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)
