Compatible with every major AI agent and IDE
What is the Currency Math Engine MCP Server?
When an AI Agent attempts to calculate an invoice discount or sum up a shopping cart, it relies on floating-point arithmetic. This often results in disastrous errors like $0.1 + $0.2 = $0.30000000000000004, causing billing systems to reject the payload. This MCP solves that entirely.
The Superpowers
- Integer Accuracy: Uses
currency.jsto perform mathematical operations natively under the hood using integers, preventing floating-point precision loss. - Billing Shield: Ensures that all Agent-driven financial payloads (Stripe, Xero, Shopify) are mathematically perfect before transmission.
Built-in capabilities (1)
Pass the base amount, the operation (add, subtract, multiply, divide, format), and the second value. The engine uses integer-based math to avoid floating-point rounding errors. Performs strict integer-based financial mathematics. Prevents floating-point hallucination when agents calculate invoices, taxes, and cart totals

Frequently asked questions
Why can't the LLM do this math?
LLMs predict the next logical token; they don't use internal ALU processors for math. This leads to hallucinations in complex decimal arithmetic.
Does it support different currencies?
Yes, it handles any currency format seamlessly by focusing strictly on the numerical value representation.
What operations are supported?
Addition, subtraction, multiplication, and division.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query Currency Math Engine tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
