The existing everyday_calculate tool exposes 67 calculators through three ordinary MCP tool actions. The server still has 14 top-level tools. Calculation inputs are processed remotely without saving a personal history.

1. Call everyday_calculate with {"request":{"action":"catalog","query":"energy"}}. Results are paginated; use the returned nextOffset.
2. Call it with {"request":{"action":"describe","calculator":"home.energy_cost"}} to read that calculator's exact input schema, example, assumptions and sources.
3. Call it with action: calculate, the same calculator ID, and the validated example or user-supplied values in parameters. The executable example below is generated from that calculator's descriptor.

      }
    }
  }
}

Parameters are limited to 200 KiB and results to 512 KiB. Each input schema applies smaller limits. Results include values, units and assumptions. Monetary inputs use decimal strings where specified. Supply actual rates, grading rules and measurements; calculations do not fetch prices, make payments or apply local legal rules. Random selection is explicitly marked non-deterministic.

Existing direct actions recipe_scale, shopping_merge and bill_split remain available through their original schemas.
