How to Use the Files.com MCP in Pydantic AI

Q: How do I initialize the Files.com MCP Server in Pydantic AI?

Install the slim package with mcp support and use the MCPToolset class pointing to your Vinkius URL. Pass this toolset to your Agent constructor. The framework will automatically register all 8 storage tools.

Q: How does Pydantic AI handle validation errors from Files.com tools?

If a tool like listactivityhistory returns data that violates your Pydantic models, the framework raises a validation error. This prevents your agent from making decisions based on malformed or hallucinated storage records.

Run type-safe Files.com storage operations with Pydantic AI and eliminate runtime schema errors using this MCP Server.

Perplexity

Type-Safe Directory Auditing

The `list_folders` tool returns structured directory listings that Pydantic AI validates against strict schemas at runtime. If the API returns unexpected data, your agent fails loudly instead of processing corrupted paths. This guarantees that your folder automation scripts never run on invalid directory structures. By using this type-safe approach, you prevent silent failures in production. Your agent can confidently parse folder names, sizes, and paths, knowing that every field matches your exact Pydantic models.

Strict Permission Verification

The `list_permissions` tool lets your agent check access rights with absolute type certainty. The Pydantic AI framework validates every permission object, ensuring that user IDs and access levels are correctly typed. This prevents logic errors that could lead to unauthorized file exposure. You can combine this with `list_user_groups` to build strict access-control workflows. The agent verifies group memberships against your internal schemas before allowing any file modifications.

Safe File Management via Pydantic AI MCP Server

The `get_file_details` tool retrieves metadata for specific files, allowing your agent to verify file sizes and creation dates before execution. Pydantic AI ensures that the returned metadata matches your Python types. If a file is missing or corrupted, the agent raises a validation error immediately. This type-safe structure makes running destructive tools like `delete_file` much safer. Your agent validates the file details first, confirming it has the right target before executing the deletion.

Setup guide

Set up Files.com MCP in Pydantic AI

Prerequisites

Python 3.10+ installed
pydantic-ai-slim[fastmcp] package
Active Vinkius subscription with a valid endpoint token

1

Install Pydantic AI with FastMCP
Run pip install "pydantic-ai-slim[fastmcp]". The FastMCP toolset replaces the deprecated MCPServerHTTP class with full protocol support.
2

Configure the FastMCPToolset
Pass a JSON-style config dict to FastMCPToolset with your Vinkius URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports Streamable HTTP, SSE, and Stdio transports.
3

Create and run your agent
Pass the toolset to Agent(toolsets=[toolset]) and call agent.run(). Swap openai:gpt-4o for any supported model — Anthropic, Google, Mistral, or Groq.

agent.py

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
    "mcpServers": {
        "filescom-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to Files.com tools.",
)

result = await agent.run("List recent Files.com transactions")
print(result.output)

Yes, Pydantic AI is model-agnostic. You can connect the server to local models or commercial APIs, and the framework will still enforce strict type validation on all 8 storage tools.

No, Vinkius hosts and manages the server for you. You only need to provide the hosted endpoint URL in your Python code to start running storage operations.

All validation occurs in memory within your Python runtime. Vinkius processes your user group details and file metadata inside ephemeral V8 Isolate Sandboxes, ensuring no data is stored or logged.
