What is the Deterministic Fair-Share Tip Splitter MCP Server?
Splitting a restaurant bill with shared appetizers, individual drinks, and group tips is a mathematical nightmare for LLMs. They frequently hallucinate decimal distributions and fail to balance the final grand total. The Tip Splitter MCP offloads this exact calculation to a rigorous V8 mathematical engine.
The Superpowers
- Proportional Taxation & Tipping: The engine automatically calculates each person's base subtotal based on the specific items they consumed (or shared), and then proportionally applies the exact tax and tip burden to each individual.
- Penny Reconciliation Algorithm: When fractional cents create a discrepancy between the calculated individual totals and the actual receipt grand total, the engine automatically reconciles the missing or extra penny to guarantee 100% mathematical closure.
- Shared Consumption Mapping: Allows mapping a single item (like 'Nachos') to multiple consumers (e.g., 'Alice' and 'Bob'). The engine dynamically splits the price before applying secondary rates.
- Zero-Dependency Execution: Operates entirely natively within the V8 runtime, guaranteeing extreme speed and precision without pulling heavy external libraries.
Built-in capabilities (1)
You must provide the items as a stringified JSON array, along with the total taxAmount and tipPercentage. Deterministically calculates individual bill shares, proportionally distributing taxes and tips among consumers based on their exact items, and resolving rounding discrepancies
Why Cursor?
Cursor's Agent mode turns Deterministic Fair-Share Tip Splitter into an in-editor superpower.

Frequently asked questions
How does it handle shared items like an appetizer?
The agent passes an array of 'consumers' for each item. If 'Nachos' ($15) has consumers ['John', 'Jane'], the engine automatically divides the base cost ($7.50 each) before proportionally applying their individual tax and tip burden.
Why do LLMs fail at this without an MCP?
LLMs lack true mathematical persistence. When calculating multi-step proportions (subtotal -> ratio -> tax allocation -> tip allocation -> fractional rounding), they often lose tracking of pennies, resulting in individual totals that don't add up to the receipt's grand total.
What is the 'Penny Reconciliation Algorithm'?
Due to floating-point toFixed(2) rounding on 5 different people, the sum of individual owed amounts might equal $100.01 while the actual grand total is $100.00. The engine detects this and surgically subtracts or adds the penny discrepancy to guarantee an exact match.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
