## 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 Files com MCP server, and what's possible with it?

The Files.com MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Files.com account. It provides structured and secure access to your cloud storage and file management resources, so your agent can perform actions like listing folders, managing permissions, generating upload keys, and handling file shares on your behalf.
- Folder navigation and organization: Ask your agent to list and explore folders within your Files.com account, making it easy to locate and organize files.
- Permission management: Allow the agent to retrieve, review, and delete access permissions for files or folders, keeping your data secure and access controlled.
- Secure file uploading: Have your agent generate S3 upload keys so you can temporarily host files for easy import, sharing, or collaboration across teams.
- Group and share link management: Let your agent list user groups or delete share links to efficiently manage who has access to important documents and shared resources.
- API key lifecycle control: Instruct your agent to revoke API keys when needed, ensuring only authorized integrations remain active for your account.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `FILES_COM_DELETE_API_KEY` | Delete API Key | Tool to delete an API key. Use when you need to revoke an API key after confirming its identifier. |
| `FILES_COM_DELETE_PERMISSION` | Delete Permission | Removes a permission grant that allows a user or group to access a specific file or folder path on Files.com. A permission ID can be obtained from the LIST_PERMISSIONS action. Use this tool when you need to revoke access that was previously granted to a user or group for a specific resource. Note: Requires administrative permissions on the Files.com site. |
| `FILES_COM_DELETE_SHARE` | Delete Share | Delete a specified share link (bundle) on Files.com. This operation is idempotent - it succeeds even if the share link has already been deleted or doesn't exist. Use this to revoke public access to shared files/folders when you have the share ID. |
| `FILES_COM_GET_S3_KEY_FOR_UPLOAD` | Get S3 Key for Upload | Tool to generate a temporary key for file uploads by uploading the file to Files.com. Useful when you need to host a local file temporarily before importing or sharing. |
| `FILES_COM_LIST_FOLDERS` | List Folders | Lists folders in Files.com with optional filtering, sorting, and pagination. Returns a paginated list of folders with metadata. Useful for browsing folder structure, finding specific folders by name, or retrieving folders under a specific parent. |
| `FILES_COM_LIST_GROUPS` | List Groups | Retrieves a paginated list of all groups from Files.com. Groups are used to organize users and manage permissions collectively. Use this action to discover available groups, check group membership, or before performing group-based permission operations. Returns group details including IDs, names, member lists, and access permissions (FTP, SFTP, WebDAV, REST API). |
| `FILES_COM_LIST_PERMISSIONS` | List Permissions | Retrieve permissions for a specified path on Files.com. Use when you need to inspect who has access and what level for a given file or folder path. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Files com MCP server is an implementation of the Model Context Protocol that connects your AI agent to Files com. It provides structured and secure access so your agent can perform Files com 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 Files com
- 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 Files com
- MCPServerStreamableHTTP connects to the Files com 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 Files com 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 Files com
    composio = Composio(api_key=api_key)
    session = composio.create(
        user_id=user_id,
        toolkits=["files_com"],
    )
    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 Files com endpoint
- The agent uses GPT-5 to interpret user commands and perform Files com operations
- The instructions field defines the agent's role and behavior
```python
# Attach the MCP server to a Pydantic AI Agent
files_com_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY})
agent = Agent(
    "openai:gpt-5",
    toolsets=[files_com_mcp],
    instructions=(
        "You are a Files com assistant. Use Files com 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
- Files com 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 Files com.\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 Files com
    composio = Composio(api_key=api_key)
    session = composio.create(
        user_id=user_id,
        toolkits=["files_com"],
    )
    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
    files_com_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY})
    agent = Agent(
        "openai:gpt-5",
        toolsets=[files_com_mcp],
        instructions=(
            "You are a Files com assistant. Use Files com 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 Files com.\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 Files com through Composio's Tool Router. With this setup, your agent can perform real Files com 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 + Files com for workflow automation)
This architecture makes your AI agent "agent-native", able to securely use APIs in a unified, composable way without custom integrations.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Files com MCP?

With a standalone Files com MCP server, the agents and LLMs can only access a fixed set of Files com tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Files com 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 Files com tools.

### Can I manage the permissions and scopes for Files com while using Tool Router?

Yes, absolutely. You can configure which Files com 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 Files com data and credentials are handled as safely as possible.
