Perplexity

Type-safe MaintainX work orders

Every response from `get_work_order_details` is validated against your Pydantic models. If the API returns garbage, the agent stops immediately. This prevents silent data corruption. You get a clean, validated object every time the agent talks to the MaintainX platform.

Asset data validation

Use `list_facility_locations` to structure your agent's understanding of the site. Pydantic AI enforces the schema for every location and asset retrieved. Your agent doesn't guess fields. It works with a strict, typed representation of your facility that matches your code definition.

Reliable status transitions

Execute `update_work_order_status` with full confidence. The framework verifies that the status string conforms to your expected types before sending it to the server. No more hallucinated fields or incorrect status codes. Your agent interacts with the API exactly how you intended.

Setup guide

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

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

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

Common questions about MaintainX MCP in Pydantic AI

Install the slim package and use `MCPToolset`. Pass it into your agent instance to gain access to the MaintainX toolset.

It does. Because the framework validates every MCP response against your Pydantic models, the agent cannot process data that doesn't fit your schema.

The server runs externally and uses a single endpoint token for auth. Your Pydantic models define the structure, but Vinkius manages the secure connection.

You can. The framework is model-agnostic, so you can point it at local LLMs or cloud providers and still benefit from the same type-safe validation.

The agent will raise a validation error immediately. This stops the execution flow rather than allowing the agent to proceed with invalid data.
