Type-safe invoice creation

Stop worrying about bad API payloads. Every response from `create_invoice` is validated against your Pydantic models, ensuring your agent never processes malformed billing data. If the server returns unexpected fields, the agent catches the mismatch immediately. This keeps your financial records consistent and prevents silent failures in your billing pipeline.

Accurate quote-to-invoice conversion

Use `convert_quote_to_invoice` to safely move deals forward. The Pydantic AI framework validates the conversion output before your agent acts on it, protecting your data integrity. It bridges the gap between sales proposals and finalized invoices. Your agent logic stays clean because it only handles verified, correct data structures.

Reliable invoice status tracking

Monitor your revenue streams using `list_invoices_by_status`. This allows your agent to categorize billing records based on their current state, such as paid or pending. You define the expected schema for these lists in your Pydantic models. This ensures your agent logic is always working with valid, structured data when it processes `list_invoices`.

Setup guide

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

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

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

Common questions about Paycove MCP in Pydantic AI

Every tool response is strictly validated against your models. If Paycove sends a response that doesn't match your expected types, your agent triggers a validation error, preventing corrupted data from entering your system.

Yes. You define the structure for invoice objects, and the agent uses `list_invoices` to retrieve and validate the data. This makes building automated reports straightforward.

Your billing records are processed through a zero-trust, ephemeral sandbox. No sensitive data is cached outside your authenticated session, keeping your payment history and client records private.

Call `check_paycove_status` before starting your agent tasks. This confirms the server is reachable and ready to process your requests.

The server returns an error which your Pydantic AI agent catches. You can then log the issue or retry the `create_product` request based on your error-handling logic.
