How to Use the Zixflow MCP in Pydantic AI

Q: How does Pydantic AI ensure data integrity when listing Zixflow records?

The listcollectionrecords tool returns validated JSON, meaning the agent knows exactly what fields to expect. This prevents the system from hallucinating or misinterpreting fields.

Q: If I need to delete data with Pydantic AI, how is it handled?

The deletecollectionrecord tool performs the deletion, and because the framework validates inputs, your agent can only attempt deletions on records it knows are properly formatted.

Q: Can Zixflow collections be managed using Pydantic AI?

Yes. Agents can call listcollections to see all available collection types, then use the validated tools like createcollectionrecord to safely add new records.

Guarantee data correctness in production with the Pydantic AI framework and Zixflow.

Type-Safe Collection Management via MCP Server

When your agent needs to write a record, `create_collection_record` lets it safely add data. Because every response is validated against Pydantic models, you never get unexpected fields or corrupted data types.

Reliable Data Updates and Retrieval

You can update records using `update_collection_record`, but the real safety comes from the validation layer. If the API sends bad field names, your agent fails loudly with a clear error—no silent corruption.

Audit Trails and Transactions

The framework allows agents to check transactions using `list_wallet_transactions`. Since Pydantic validates everything, you know the transaction data received is structured correctly for immediate use.

Setup guide

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

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

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