Check local laws using this MCP Server

`get_state_mitigation_duty` queries the exact legal requirements for landlords to find a replacement tenant in any US state. Your agent uses this data to verify if a landlord must actively market the property or if they can simply charge you for the remaining months. This means you do not have to dig through state statutes yourself. Claude Desktop reads the output to build a defense strategy based on local landlord-tenant laws.

Run gross loss math in Claude Desktop

`calculate_gross_loss` computes the total outstanding rent for the remaining lease duration based on monthly rent and move-out dates. It gives your agent the exact baseline dollar figure before any legal mitigations or security deposits are applied. This MCP handles the date math automatically to prevent manual errors. It outputs a clear breakdown that you can copy straight into an email to your landlord.

Estimate reasonable lease settlements

`estimate_lease_break_settlement` calculates a realistic settlement range by weighing the remaining rent against state mitigation laws and average re-rental times. Your agent uses these numbers to suggest a starting offer for negotiations. Having this range prevents you from overpaying during a lease break. You get a clear picture of your actual financial exposure in seconds.
