Run multi-step lease math with LangChain

The `calculate_gross_loss` tool computes the exact financial hit when a tenant walks away early. Pass the raw lease parameters into your chain and let the model determine the total uncollected rent. This MCP feeds raw numbers directly into your pipeline without manual copy-pasting. By running this calculation, your agent gets the baseline exposure instantly. LangSmith traces the entire sequence so you can inspect the exact inputs of the calculation.

Map local legal rules for lease breaks

The `get_state_mitigation_duty` tool maps local landlord-tenant laws that vary wildly by state. Some states force landlords to find a new tenant immediately, while others let them collect rent until the lease ends. Your agent invokes the function to determine if mitigation is legally required. This legal obligation automatically feeds into the next step of your chain to adjust the final penalty estimate.

Estimate realistic settlement numbers

The `estimate_lease_break_settlement` tool calculates a realistic target range based on real-world factors. Litigation is expensive, so settling is usually the smart move. Negotiators want a realistic starting point based on actual financial exposure. Your agent suggests a fair buyout number using these calculations to give you a solid negotiation starting point.
