Perplexity

Type-Safe Avaza MCP Server Integration

Silent API failures destroy production systems. When your agent calls `list_tasks` or `get_project`, Pydantic AI validates the exact structure of the returned payload against your defined models. If the payload changes or drops a required field, the framework fails loudly. You catch the validation error immediately instead of letting hallucinated data corrupt your downstream logic.

Flawless Billing Execution

Generating financial records requires absolute precision. You can configure an agent to execute `create_timesheet` and `list_invoices` with complete confidence that the inputs match the required schema. The framework parses the arguments before the HTTP request ever leaves your server. This guarantees your database stays clean and your clients get billed for the correct hours.

Model-Agnostic Project Creation

Swapping underlying language models shouldn't break your tool calling logic. You can use OpenAI today and local models tomorrow to trigger `create_project` and `update_task`. Just pass the Vinkius URL to the MCPToolset class and inject it into your agent. The unified approach handles the translation, ensuring your company contacts from `list_contacts` are always formatted correctly.

Setup guide

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

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

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