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 does Windsurf discover MCP tools?
Windsurf reads the mcp_config.json file on startup and connects to each configured server via Streamable HTTP. Tools are listed in the MCP panel and available to Cascade automatically.
Can Cascade chain multiple MCP tool calls?
Yes. Cascade is an agentic system. it can plan and execute multi-step workflows, calling several tools in sequence to accomplish complex tasks without manual prompting between steps.
Does Windsurf support multiple MCP servers?
Yes. Add as many servers as needed in mcp_config.json. Each server's tools appear in the MCP panel and Cascade can use tools from different servers in a single flow.
