Perplexity

Type-safe Clientjoy customer data

Silent data corruption ruins CRM systems. When your agent calls `get_customer_details` through the Clientjoy MCP Server, Pydantic AI validates every single field. If the API returns a string instead of an int, the system throws a loud validation error. You care about correctness above all else. Grabbing the entire client list via `list_customers` guarantees you get exact matches against your internal schemas. No guessing if the agent made up an email address.

Strict Pydantic AI lead creation

Pushing bad data into your sales pipeline is a nightmare. Before your agent fires `create_new_lead`, the framework ensures the payload perfectly matches the required tool schema. It blocks malformed requests before they hit the network. The same logic applies to your catalog. Fetching `list_service_items` means your agent only quotes actual products with real prices. It physically cannot invent a service tier that doesn't exist.

Validated billing and proposals

Financial records demand absolute precision. Your agent checks `list_billing_invoices` to audit outstanding accounts. Every invoice amount, date, and status gets parsed into a strict Python object. Contract generation follows the exact same rules. The agent pulls active quotes using `list_sales_proposals`. You pass the MCPToolset to your Pydantic Agent, and it handles the streamable HTTP connection flawlessly.

Setup guide

Set up Clientjoy 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": {
        "clientjoy-alternative-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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