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

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.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
