Perplexity

Type-safe loan comparisons with this MCP Server

Stop worrying about silent data corruption in your financial agents. This MCP Server integrates with Pydantic AI to ensure that every response from `compare_two_loans` is validated against strict Python type schemas before your agent can use it. No weird floats, no missing fields. If the tool returns an unexpected structure, the framework fails loudly with a validation error. This guarantees that your agent never makes critical financial recommendations based on malformed or incomplete data.

Calculate exact amortization schedules safely

Generate Price or SAC payment tables using `calculate_loan_amortization`. The tool calculates the total interest, total paid, and individual installment amounts based on the principal and term you provide. Pydantic AI parses the tool's JSON output directly into structured Python models. Your agent can confidently process the installment lists, knowing the types are correct and the math is mathematically sound.

Determine payoff acceleration timelines

Use `calculate_loan_payoff_speed` to find out how much time and interest a user saves by making extra principal payments. The tool returns the exact number of months shaved off the loan and the total interest savings. Because Pydantic AI is model-agnostic, you can use this tool with any LLM provider. The framework handles the schema validation, ensuring the agent passes valid numeric inputs and receives structured financial outputs.

Setup guide

Set up Intelligent Loan Comparator 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": {
        "intelligent-loan-comparator-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Intelligent Loan Comparator transactions")
print(result.output)

Common questions about Intelligent Loan Comparator MCP in Pydantic AI

Install the `pydantic-ai-slim[mcp]` package and initialize the `MCPToolset` with your Vinkius HTTP endpoint. Pass this toolset into the `Agent` constructor to expose tools like `calculate_loan_amortization` to your model.

Yes. The tool schemas are automatically converted into Pydantic models. When your agent calls `compare_two_loans`, the framework validates the inputs and outputs at runtime, throwing clear errors if any financial fields are missing or malformed.

Yes, this MCP Server works with any model supported by Pydantic AI, including local models run via Ollama. The math calculations run entirely on the Vinkius server, so your local model only needs to handle the tool calling.

The tool will return a clear mathematical error or the framework will block the call during input validation. This prevents your agent from attempting to calculate amortization schedules with negative interest rates or zero-month durations.

Yes. All calculations for loan amounts, interest rates, and payment frequencies run within an isolated, zero-trust MCP sandbox. No data is stored, logged, or transmitted outside the secure runtime environment.
