How to Use the Mashvisor MCP in Pydantic AI

Q: Can I use Pydantic AI to compare Airbnb and traditional rental yields using Mashvisor tools?

Yes, your Pydantic AI agent can query getrentalrates and getairbnblistings concurrently. The framework validates both data streams, allowing your agent to safely calculate the ROI differences.

Bring type-safe real estate analysis to Pydantic AI with runtime validation for every property and rental yield.

Type-safe property analysis with Pydantic AI

This MCP Server integrates `get_property` and `get_investment_analysis` with Pydantic AI to enforce strict validation on every real estate metric. Don't worry about your Pydantic AI agent hallucinating rental income numbers or processing malformed Mashvisor data. When your agent calls these tools, the Mashvisor response is immediately validated against strict Python types. If the upstream Mashvisor data doesn't match your expected schema, the Pydantic AI framework raises a loud validation error. This prevents corrupted rental yields from polluting your financial models or causing silent calculation errors downstream.

Validate short-term rental metrics at runtime

This MCP Server exposes `get_airbnb_listings` and `get_airbnb_property` to Pydantic AI for runtime validation of short-term rental data. Evaluating vacation rentals requires processing volatile data points like occupancy rates and nightly pricing. Your Pydantic AI agent uses these tools to pull current active listings and validate them instantly. This runtime security is critical when building automated bidding or underwriting bots with Pydantic AI. You can trust that the cash-on-cash returns your Pydantic AI agent analyzes from Mashvisor are structurally sound and ready for your investment pipeline.

Filter properties with strict type boundaries

This MCP Server connects `list_properties` and `get_city_listings` to Pydantic AI for type-safe property filtering. Finding the right asset requires querying Mashvisor with precise parameters. Your Pydantic AI agent calls these tools to filter by price and bedroom count, validating input parameters before sending them. You can also rely on `get_historical_performance` to analyze multi-year seasonality trends. The historical Mashvisor data arrays are validated at the schema level, ensuring your Pydantic AI model receives clean, structured lists of monthly metrics.

Setup guide

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

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

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