What is the Finance Toolkit MCP Server?

Financial mathematics require absolute deterministic precision. A single hallucination by an LLM in an interest rate or loan amortization could lead to disastrous business decisions. The Finance Toolkit MCP Server solves this by delegating the math to an exact V8 Javascript engine.

The Superpowers

Flawless Amortization: Compare SAC (Constant Amortization) and PRICE (French) loan tables instantly, providing exact summaries without blowing up the context window.
Compound Certainty: Calculate exponential compound interests with customizable frequencies.
Investment Tracking: Reliably compute ROI (Return on Investment) and net profit margins.
Absolute Privacy (Local): Sensitive financial planning data, loan principals, and proprietary rates never leave your local infrastructure.

Built-in capabilities (4)

calculate_amortization

Rate must be periodic decimal (e.g. monthly rate). Type must be "SAC" or "PRICE". Generates a summarized amortization schedule (SAC or PRICE table)

calculate_compound_interest

g. 0.05). Frequency is times per year interest is compounded (default 1). Calculates compound interest over a period of time

calculate_roi

Calculates the Return on Investment (ROI) percentage

calculate_simple_interest

Rate must be decimal (e.g. 0.05 for 5%). Calculates simple interest over a period of time

Why Cursor?

Cursor's Agent mode turns Finance Toolkit into an in-editor superpower. Ask Cursor to generate code using live data from Finance Toolkit and it fetches, processes, and writes. all in a single agentic loop. 4 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.

—
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
—
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
—
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
—
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

FAQ

Frequently asked questions

Why doesn't the amortization tool return the full 360-month table?

Returning 360 lines of JSON would severely bloat the LLM's context window, increasing API costs and causing distraction. We return a "Smart Summary" (total paid, total interest, first and last installments) which is perfect for AI decision-making.

Are the compound interest calculations precise enough for banking?

Yes. The underlying engine relies on JavaScript's high-precision floating-point arithmetic (IEEE 754 standard). Outputs are rounded to 2 decimal places specifically for financial display standards.

Can it compare SAC vs PRICE automatically?

An AI agent using this MCP can execute the tool twice in parallel—once for SAC and once for PRICE—and instantly write a comparative analysis report for you based on the exact totals.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
