Gemini
What is the Percentage Calculation Engine MCP Server?
LLMs frequently fail when applying layered financial math, such as calculating a 15% discount followed by a 20% tax. They guess the answer based on training data. This MCP brings pure, native Javascript logic to percentage math.
The Superpowers
- Flawless Financials: Ensure your AI calculates invoice discounts, VAT taxes, and interest correctly every single time.
- Absolute Determinism: No stochastics. Just native mathematical evaluation executed at the edge.
Built-in capabilities (2)
Increases or decreases a value by X percent deterministically (use negative percent for discount)
Pass the base value and the percentage to compute. Essential for discount calculations, tax rates, and financial reports. Calculates X percent of a total value deterministically
Why Google ADK?
Google ADK natively supports Percentage Calculation Engine as an MCP tool provider. declare Vinkius Edge URL and the framework handles discovery, validation, and execution automatically. Combine 2 tools with Gemini's long-context reasoning for complex multi-tool workflows, with production-ready session management and evaluation built in.

Why teams choose Vinkius for Percentage Calculation Engine in Google ADK
The Percentage Calculation Engine MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 2 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Google ADK only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.
* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
Percentage Calculation Engine for Google ADK
Every tool call from Google ADK to the Percentage Calculation Engine MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can it calculate discounts?
Yes, by passing a negative percentage.
Is it deterministic?
Absolutely. Pure math evaluation local.
Does it support tax addition?
Yes, simply use the increase_by function.
How does Google ADK connect to MCP servers?
Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.
Can ADK agents use multiple MCP servers?
Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.
Which Gemini models work best with MCP tools?
Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
