How to Use the Deterministic Fair-Share Tip Splitter MCP in Windsurf

Q: How does the Deterministic Fair-Share Tip Splitter work inside Windsurf?

The server registers the splitbill tool directly with Cascade. When you feed Cascade a raw receipt, it structures the items into a JSON array, specifies the tax and tip, and calls the tool to get an exact mathematical breakdown.

Q: How do I install the Deterministic Fair-Share Tip Splitter MCP Server on Windsurf?

You add the server configuration to your /.codeium/windsurf/mcpconfig.json file under the mcpServers key. Once saved, Cascade auto-discovers the splitbill tool and is ready to calculate splits.

Q: What happens if there is a leftover penny from division?

The splitbill tool uses a deterministic largest-remainder algorithm to assign the leftover fraction of a cent to the person with the largest individual total. This guarantees the sum of all split shares equals the exact receipt total.

Let Windsurf run the Deterministic Fair-Share Tip Splitter MCP Server to resolve messy restaurant bills with zero fractional penny errors.

Perplexity

Proportional tax and tip allocation via Windsurf

The `split_bill` tool calculates exact individual shares of a restaurant bill by tying tax and tip directly to what each person ordered. Cascade handles the input parsing, taking raw receipt text and organizing it into the required JSON array of items before invoking the math engine. You don't have to manually match who ordered the expensive steak versus the cheap salad. The server distributes the tax and tip proportionally, ensuring no one gets subsidized or overcharged during group dinners.

Deterministic penny rounding without floating-point errors

The `split_bill` tool resolves the classic fractional penny problem by assigning the remaining fraction of a cent to the highest individual bill total. Cascade runs this calculation instantly, making sure the sum of all individual payments matches the receipt total down to the exact penny. This eliminates the awkward social friction of having a leftover deficit when splitting bills. The math is completely deterministic, meaning you get the exact same split every single time you run the tool.

Multi-step autonomous bill calculations with Cascade

The `split_bill` tool integrates with Windsurf as an MCP Server to let Cascade execute the entire receipt parsing and splitting sequence in one go. You give Cascade a raw text dump of a receipt, and it automatically structures the items, extracts the tax, calculates the tip, and runs the splitter. Because Cascade chains these steps autonomously, you don't need to write a script or manually format the JSON array. The agent reads the context, plans the execution, and hands you the final, ready-to-request Venmo breakdown.
