What is the Deterministic 50/30/20 Budget Engine MCP Server?
Asking an LLM to calculate personal or corporate finances is dangerous. AI models frequently miscalculate decimals, drop expenses from large arrays, or hallucinate total percentages. The Budget Engine MCP solves this by offloading strict financial auditing to a hyper-precise V8 mathematical engine.
The Superpowers
- Strict 50/30/20 Algorithmic Enforcement: You map the expenses, and the engine mathematically enforces the golden rule of finance (50% Needs, 30% Wants, 20% Savings/Debt), calculating the exact target capital for your given income.
- Micro-Precision Deviations: Generates exact dollar and fractional percentage deviations. It instantly tells you if your 'Wants' category is $250.45 over budget, preventing LLM math hallucinations and allowing immediate tactical corrections.
- Deficit & Surplus Diagnostics: Automatically calculates the final monthly surplus or deficit, triggering strict structural alerts ('Deficit' vs 'Healthy') accompanied by algorithmic recommendations.
- Zero-Dependency Execution: Operates entirely natively within the V8 runtime, guaranteeing extreme speed and deterministic precision without relying on fragile external financial APIs.
Built-in capabilities (1)
You must provide the exact monthly income and a stringified JSON array of categorized expenses. Instantly applies the 50/30/20 financial rule to an income and expenses list, returning strict algorithmic deviations, percentages, and surplus/deficit health checks

Frequently asked questions
Does the engine automatically guess the category of an expense?
No. The AI agent calling the tool is responsible for tagging each expense as 'need', 'want', or 'saving'. The MCP acts as an infallible mathematical referee, receiving the categorized list and computing the exact metrics and deviations.
Why use an MCP instead of having the LLM do the math?
Because LLMs hallucinate math. If you give an AI 45 different expenses to sum up, it will almost certainly miscalculate the total or botch the exact percentage deviation. The V8 engine calculates numbers deterministically with 100% precision.
What happens if I spend more than my income?
The engine perfectly calculates a negative surplus (deficit) and strictly alters the 'healthStatus' to 'Deficit', triggering a warning recommendation that instructs your agent to look at the deviations to cut costs.
How do I add an MCP server to Claude Code?
Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
How do I list all connected MCP servers?
Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
