How to Use the Fluxiom MCP in Pydantic AI

Q: How do I register the Fluxiom MCP Server in Pydantic AI?

Install the package using pip install "pydantic-ai-slimmcp" and initialize MCPToolset with your server URL. Pass this toolset to your Agent instance to give it type-safe access to your assets.

Q: Can I manage branded portals using Fluxiom and Pydantic AI?

Yes, you can use liststages to fetch your active portals. The framework validates the portal list against its internal schema, letting your agent safely route assets to the correct stage.

Q: How do I check file history?

Use the getassetversions tool to retrieve the version history of any file. This returns a typed list of past versions, allowing your agent to audit changes safely.

Strict type validation with Pydantic AI

The `get_asset` tool returns file details from the MCP Server that the framework validates against strict Python schemas at runtime. If the API returns unexpected metadata, Pydantic AI fails immediately rather than letting corrupted data slip into your database. This strict validation prevents silent failures in your production pipelines. You get clean, typed objects for every file, making your asset-processing code predictable and easy to debug.

Type-safe taxonomy management

The `list_tags` tool fetches your organizational taxonomy, casting the results into validated Pydantic models. Your agent can inspect these tags knowing the data structure matches your codebase exactly. When creating new categories with `create_tag`, the framework ensures the request payload matches the required schema before sending it. This eliminates API errors caused by malformed payloads.

Safe metadata updates

The `update_asset` tool lets your agent modify file metadata with full type-safety. The framework checks the update parameters before execution, ensuring the agent doesn't write invalid data types to your assets. You can pair this with `get_account_details` to verify storage limits and account status before pushing changes. The agent operates within strict type constraints, protecting your repository from bad metadata.

Setup guide

Set up Fluxiom 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": {
        "fluxiom-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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