Type-safe AccuLynx tools for Pydantic AI

Every response from `get_job_details` is validated against Pydantic models at runtime. If the API returns garbage, your agent stops immediately. `list_payments` provides structured data that fits your schema requirements. You avoid the headache of parsing unexpected fields from your AccuLynx account.

Manage leads via Pydantic AI

Call `create_lead` with confidence knowing the input fields are checked by your models. You catch errors before they ever reach the AccuLynx database. `list_leads` returns a clean array that your agent can process without manual cleaning. It keeps your roofing sales pipeline predictable.

Error-free AccuLynx integration with Pydantic AI

You define the expected shape of roofing job records in your agent code. The MCPToolset handles the conversion from the server to your Python objects. This approach ensures that every call to `list_payments` results in usable, typed data. You stop debugging data format issues and focus on agent behavior.

Setup guide

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

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

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

Common questions about AccuLynx MCP in Pydantic AI

Install the pydantic-ai-slim package and use the MCPToolset to register your server URL. This allows the agent to call AccuLynx tools as native Python functions.

Yes, it enforces your Pydantic models at runtime. If the AccuLynx API deviates from your expected format, the agent raises a validation error instead of failing silently.

The server supports Streamable HTTP and SSE. You just point the MCPToolset at your endpoint and it handles the communication.

You can pass the toolset to multiple Pydantic AI agents. The server remains running externally, serving requests as needed.

We enforce strict validation schemas on every data packet. Your lead names and job IDs are handled in a type-safe environment that rejects any malformed or suspicious payloads.
