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
Why Mastra AI?

Currency Math Engine for Mastra AI
Every tool call from Mastra AI to the Currency Math Engine MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
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 Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
