This guide will help you understand how to give your Pydantic AI agent real control over a Dropbox account through Composio's Dropbox MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Dropbox with - [ChatGPT](https://composio.dev/toolkits/dropbox/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/dropbox/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/dropbox/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/dropbox/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/dropbox/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/dropbox/framework/codex) - [Cursor](https://composio.dev/toolkits/dropbox/framework/cursor) - [VS Code](https://composio.dev/toolkits/dropbox/framework/vscode) - [OpenCode](https://composio.dev/toolkits/dropbox/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/dropbox/framework/openclaw) - [Hermes](https://composio.dev/toolkits/dropbox/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/dropbox/framework/cli) - [Google ADK](https://composio.dev/toolkits/dropbox/framework/google-adk) - [LangChain](https://composio.dev/toolkits/dropbox/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/dropbox/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/dropbox/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/dropbox/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/dropbox/framework/crew-ai) ## TL;DR Here's what you'll learn: - How to set up your Composio API key and User ID - How to create a Composio Tool Router session for Dropbox - How to attach an MCP Server to a Pydantic AI agent - How to stream responses and maintain chat history - How to build a simple REPL-style chat interface to test your Dropbox workflows ## What is Pydantic AI? Pydantic AI is a Python framework for building AI agents with strong typing and validation. It leverages Pydantic's data validation capabilities to create robust, type-safe AI applications. Key features include: - Type Safety: Built on Pydantic for automatic data validation - MCP Support: Native support for Model Context Protocol servers - Streaming: Built-in support for streaming responses - Async First: Designed for async/await patterns ## What is the Dropbox MCP server, and what's possible with it? The Dropbox MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Dropbox account. It provides structured and secure access to your cloud files, so your agent can perform actions like searching, uploading, organizing, reading, and deleting files and folders on your behalf. - Smart file search and retrieval: Ask your agent to search for files or folders by name, keyword, or within specific directories, and quickly locate what you need. - Automated file uploads and folder creation: Direct your agent to create new folders for organization or request file uploads with unique shareable links, streamlining content collection and storage. - Seamless file reading and downloads: Have your agent read the contents of any file or download important documents from your Dropbox, whenever you need them. - Effortless organization and cleanup: Let your agent move, delete, or reorganize files and folders to keep your Dropbox tidy and efficient. - Account insights and management: Retrieve up-to-date details about your Dropbox account, including user info and storage status, for complete oversight. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `DROPBOX_CREATE_FILE_REQUEST` | Create file request | Tool to create a new file request in dropbox. use when you need to request files from others by generating a unique link for uploads to a specified dropbox folder, optionally with a deadline. | | `DROPBOX_CREATE_FOLDER` | Create folder | Tool to create a new folder at a specified path in dropbox. use when you need to organize files by creating a new directory. requires the 'files.content.write' scope. | | `DROPBOX_CREATE_PAPER` | Create paper document | Creates a new dropbox paper document at the specified path using html or markdown content. | | `DROPBOX_DELETE_FILE_OR_FOLDER` | Delete file or folder | Permanently deletes the file or folder at the specified path in dropbox. use when you need to remove a specific file or folder. requires the `files.content.write` scope. | | `DROPBOX_GET_ABOUT_ME` | Get about me | Tool to get information about the current user's dropbox account. use when you need to retrieve account details like email, name, or account type. | | `DROPBOX_LIST_FILES_IN_FOLDER` | List files in folder | Tool to list files and folders in a specified dropbox directory. use when you need to see the contents of a folder, including subfolders if recursive is true. | | `DROPBOX_LIST_FOLDERS` | List folder contents | Retrieves a list of folders, files, and deleted entries from a specified dropbox path. | | `DROPBOX_MOVE_FILE_OR_FOLDER` | Move file or folder | Move file or folder | | `DROPBOX_READ_FILE` | Read a file | Downloads a file from the specified dropbox path, requiring `files.content.read` scope. | | `DROPBOX_SEARCH_FILE_OR_FOLDER` | Search File or Folder | Tool to search for files and folders in dropbox. use when you need to find an item by name or content, optionally within a specific path or with other filters, and paginate through results. example: search for 'report.docx' in the '/finance' folder. | | `DROPBOX_UPLOAD_FILE` | Upload File | Uploads a file to a specified path in the user's dropbox, with options for handling existing files. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Dropbox MCP server is an implementation of the Model Context Protocol that connects your AI agent to Dropbox. It provides structured and secure access so your agent can perform Dropbox operations on your behalf through a secure, permission-based interface. With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster. ## Step-by-step Guide ### 1. Prerequisites Before starting, make sure you have: - Python 3.9 or higher - A Composio account with an active API key - Basic familiarity with Python and async programming ### 1. Getting API Keys for OpenAI and Composio OpenAI API Key - Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models, or you can connect to another model provider. - Keep the API key safe. Composio API Key - Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs). - Navigate to your API settings and generate a new API key. - Store this key securely as you'll need it for authentication. ### 2. Install dependencies Install the required libraries. What's happening: - composio connects your agent to external SaaS tools like Dropbox - pydantic-ai lets you create structured AI agents with tool support - python-dotenv loads your environment variables securely from a .env file ```bash pip install composio pydantic-ai python-dotenv ``` ### 3. Set up environment variables Create a .env file in your project root. What's happening: - COMPOSIO_API_KEY authenticates your agent to Composio's API - USER_ID associates your session with your account for secure tool access - OPENAI_API_KEY to access OpenAI LLMs ```bash COMPOSIO_API_KEY=your_composio_api_key_here USER_ID=your_user_id_here OPENAI_API_KEY=your_openai_api_key ``` ### 4. Import dependencies What's happening: - We load environment variables and import required modules - Composio manages connections to Dropbox - MCPServerStreamableHTTP connects to the Dropbox MCP server endpoint - Agent from Pydantic AI lets you define and run the AI assistant ```python import asyncio import os from dotenv import load_dotenv from composio import Composio from pydantic_ai import Agent from pydantic_ai.mcp import MCPServerStreamableHTTP load_dotenv() ``` ### 5. Create a Tool Router Session What's happening: - We're creating a Tool Router session that gives your agent access to Dropbox tools - The create method takes the user ID and specifies which toolkits should be available - The returned session.mcp.url is the MCP server URL that your agent will use ```python async def main(): api_key = os.getenv("COMPOSIO_API_KEY") user_id = os.getenv("USER_ID") if not api_key or not user_id: raise RuntimeError("Set COMPOSIO_API_KEY and USER_ID in your environment") # Create a Composio Tool Router session for Dropbox composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["dropbox"], ) url = session.mcp.url if not url: raise ValueError("Composio session did not return an MCP URL") ``` ### 6. Initialize the Pydantic AI Agent What's happening: - The MCP client connects to the Dropbox endpoint - The agent uses GPT-5 to interpret user commands and perform Dropbox operations - The instructions field defines the agent's role and behavior ```python # Attach the MCP server to a Pydantic AI Agent dropbox_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[dropbox_mcp], instructions=( "You are a Dropbox assistant. Use Dropbox tools to help users " "with their requests. Ask clarifying questions when needed." ), ) ``` ### 7. Build the chat interface What's happening: - The agent reads input from the terminal and streams its response - Dropbox API calls happen automatically under the hood - The model keeps conversation history to maintain context across turns ```python # Simple REPL with message history history = [] print("Chat started! Type 'exit' or 'quit' to end.\n") print("Try asking the agent to help you with Dropbox.\n") while True: user_input = input("You: ").strip() if user_input.lower() in {"exit", "quit", "bye"}: print("\nGoodbye!") break if not user_input: continue print("\nAgent is thinking...\n", flush=True) async with agent.run_stream(user_input, message_history=history) as stream_result: collected_text = "" async for chunk in stream_result.stream_output(): text_piece = None if isinstance(chunk, str): text_piece = chunk elif hasattr(chunk, "delta") and isinstance(chunk.delta, str): text_piece = chunk.delta elif hasattr(chunk, "text"): text_piece = chunk.text if text_piece: collected_text += text_piece result = stream_result print(f"Agent: {collected_text}\n") history = result.all_messages() ``` ### 8. Run the application What's happening: - The asyncio loop launches the agent and keeps it running until you exit ```python if __name__ == "__main__": asyncio.run(main()) ``` ## Complete Code ```python import asyncio import os from dotenv import load_dotenv from composio import Composio from pydantic_ai import Agent from pydantic_ai.mcp import MCPServerStreamableHTTP load_dotenv() async def main(): api_key = os.getenv("COMPOSIO_API_KEY") user_id = os.getenv("USER_ID") if not api_key or not user_id: raise RuntimeError("Set COMPOSIO_API_KEY and USER_ID in your environment") # Create a Composio Tool Router session for Dropbox composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["dropbox"], ) url = session.mcp.url if not url: raise ValueError("Composio session did not return an MCP URL") # Attach the MCP server to a Pydantic AI Agent dropbox_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[dropbox_mcp], instructions=( "You are a Dropbox assistant. Use Dropbox tools to help users " "with their requests. Ask clarifying questions when needed." ), ) # Simple REPL with message history history = [] print("Chat started! Type 'exit' or 'quit' to end.\n") print("Try asking the agent to help you with Dropbox.\n") while True: user_input = input("You: ").strip() if user_input.lower() in {"exit", "quit", "bye"}: print("\nGoodbye!") break if not user_input: continue print("\nAgent is thinking...\n", flush=True) async with agent.run_stream(user_input, message_history=history) as stream_result: collected_text = "" async for chunk in stream_result.stream_output(): text_piece = None if isinstance(chunk, str): text_piece = chunk elif hasattr(chunk, "delta") and isinstance(chunk.delta, str): text_piece = chunk.delta elif hasattr(chunk, "text"): text_piece = chunk.text if text_piece: collected_text += text_piece result = stream_result print(f"Agent: {collected_text}\n") history = result.all_messages() if __name__ == "__main__": asyncio.run(main()) ``` ## Conclusion You've built a Pydantic AI agent that can interact with Dropbox through Composio's Tool Router. With this setup, your agent can perform real Dropbox actions through natural language. You can extend this further by: - Adding other toolkits like Gmail, HubSpot, or Salesforce - Building a web-based chat interface around this agent - Using multiple MCP endpoints to enable cross-app workflows (for example, Gmail + Dropbox for workflow automation) This architecture makes your AI agent "agent-native", able to securely use APIs in a unified, composable way without custom integrations. ## How to build Dropbox MCP Agent with another framework - [ChatGPT](https://composio.dev/toolkits/dropbox/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/dropbox/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/dropbox/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/dropbox/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/dropbox/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/dropbox/framework/codex) - [Cursor](https://composio.dev/toolkits/dropbox/framework/cursor) - [VS Code](https://composio.dev/toolkits/dropbox/framework/vscode) - [OpenCode](https://composio.dev/toolkits/dropbox/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/dropbox/framework/openclaw) - [Hermes](https://composio.dev/toolkits/dropbox/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/dropbox/framework/cli) - [Google ADK](https://composio.dev/toolkits/dropbox/framework/google-adk) - [LangChain](https://composio.dev/toolkits/dropbox/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/dropbox/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/dropbox/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/dropbox/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/dropbox/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 Dropbox MCP server, the agents and LLMs can only access a fixed set of Dropbox tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Dropbox and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Pydantic AI? Yes, you can. Pydantic AI 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 Dropbox tools. ### Can I manage the permissions and scopes for Dropbox while using Tool Router? Yes, absolutely. You can configure which Dropbox 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 Dropbox 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)
