MCP tools

The MCP server exposes:

• calculate_registration

• calculate_title

• calculate_vehicle_fee

• calculate_out_the_door

• get_state_fee_rules

• lookup_vin

The server is deliberately conservative. It does not fabricate government fees or vehicle attributes when authoritative data is not loaded.

npm start

Accuracy policy

State DMV, BMV, DOT, revenue, title, registration, sales-tax, plate, and EV-fee values must be verified against authoritative sources. Record effective dates where available. Never present an invented fee as an official amount.
