Perplexity

Calculate exact shares in Claude Desktop

The `split_bill` tool handles the heavy lifting of parsing your receipt. You feed it the JSON array of items and the server calculates each person's total based on their specific order. It handles the tax and tip math for you. No more arguing over who ordered the extra appetizer or why the tip is off by a few cents.

Deterministic rounding for your bills

Floating-point errors are a nightmare for shared expenses. This MCP Server forces a deterministic approach so the math always sums up to the total on the receipt. By assigning fractional penny remainders to the highest spender, the `split_bill` logic keeps the ledger clean. It's the only way to ensure the group stays square.

Claude Desktop ledger management

You can keep a history of your dining costs by keeping the output from the tool in your chat. It saves the breakdown for later reference. This makes it easy to track who owes what after a night out. You just copy the numbers from the `split_bill` output and send them to your friends.
