Common questions
Is Finanzas MCP safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.3) reached the registry 4 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.
What can I use instead?

Instalación
Claude Desktop / Claude Code (con uv)
{"mcpServers": { "finanzas": { "command": "uvx", "args": ["finanzas-mcp"] } } }
En Claude Code basta:
claude mcp add finanzas -- uvx finanzas-mcpDesde el código clonado
git clone https://github.com/MITDEVPRO/finanzas-mcpcd finanzas-mcp uv run finanzas-mcp # o: pip install -e . && finanzas-mcp
Ejemplos de uso (en tu cliente MCP)
- *"Calcula la liquidez con activo corriente 850M, pasivo corriente 260M, inventario 420M"*
- *"Valoriza por DCF: FCF 1.200, 1.350, 1.500; WACC 11%; g 2,5%; deuda neta 2.000"*
- *"¿Cuál es el Z-Score? Activos 10.000M, pasivos 6.000M, WC 1.800M, utilidades retenidas 2.500M, EBIT 900M, patrimonio 4.000M"*
- *"Tabla de un crédito de 50M a 60 cuotas, 1,1% mensual, sistema francés"*
- *"Aging de estas facturas: [{monto: 12M, dias_vencido: 45, cliente: 'ACME'}, …]"*
¿Quieres ver las salidas completas? En examples/ hay 4 casos resueltos de una misma empresa — WACC → DCF con sensibilidad → Z-Score → punto de equilibrio — con los outputs reales de cada tool.
¿Te sirvió?
Si finanzas-mcp te ahorró un cálculo (o una discusión de comité), la mejor forma de apoyarlo es una ⭐ en este repo — es lo que hace que más gente lo encuentre. Y si te falta una calculadora, abre un issue: las nuevas tools salen de ahí.
English
finanzas-mcp is an MCP (Model Context Protocol) server with 25 pure-computation finance calculators, Spanish-first with self-describing schemas. It runs locally over stdio: no internet, no databases, no state — it only computes on the numbers you provide, so it works for any company and any currency.
Tools: liquidity/profitability/efficiency/leverage ratios · DuPont (3 & 5 factor) · Altman Z-Score (3 variants) · Piotroski F-Score · working capital · CAPM (with Hamada beta) · WACC · DCF with sensitivity · valuation multiples · NPV/IRR/payback · break-even · valued cash conversion cycle ($/day per lever, multi-country) · AR aging · depreciation · loan amortization (French/German) · compound interest · indirect cash flow · Chilean tax helpers (VAT, corporate tax, monetary correction, tax shield — all parameterizable).
Install (Claude Desktop / Claude Code, requires uv):
claude mcp add finanzas -- uvx finanzas-mcpTry prompts like: *"Compute WACC: equity 60%, cost of equity 12%, cost of debt 6%, tax rate 27%"* or *"DCF this: FCF 1200, 1350, 1500; WACC 11%; g 2.5%; net debt 2000"*. Tool descriptions are in Spanish, but Claude bridges languages transparently — ask in English and it just works.
If it saves you a calculation, a ⭐ star helps others find it. Missing a calculator? Open an issue.
