Calcula Taxa Metabólica Basal (TMB) e Gasto Energético Total (GET). Três fórmulas: Mifflin-St Jeor (1990, mais precisa), Harris-Benedict (1984 revisada), Katch-McArdle (usa massa magra, requer % gordura). GET = TMB × fator de atividade. Retorna: TMB em kcal, GET em kcal, fator de atividade aplicado.
AI agents call calcular_tmb to retrieve information from Contaí — Calculadoras Fiscais Brasileiras without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameters from the server's own tool schema.
This is a pure computational/query tool that performs mathematical calculations on provided inputs (age, weight, height, activity level, optionally body fat percentage) and returns calculated metabolic rates. It has no side effects, does not create or modify data, does not execute arbitrary code or external operations, and does not involve financial transactions or data destruction.
From the tool's definition Tool description states it 'Calcula Taxa Metabólica Basal (TMB) e Gasto Energético Total (GET)' using three formulas (Mifflin-St Jeor, Harris-Benedict, Katch-McArdle) and returns calculated values.

Calcula Taxa Metabólica Basal (TMB) e Gasto Energético Total (GET). Três fórmulas: Mifflin-St Jeor (1990, mais precisa), Harris-Benedict (1984 revisada), Katch-McArdle (usa massa magra, requer % gordura). GET = TMB × fator de atividade. Retorna: TMB em kcal, GET em kcal, fator de atividade aplicado. It is categorised as a Read tool in the Contaí — Calculadoras Fiscais Brasileiras MCP Server, which means it retrieves data without modifying state.
calcular_tmb accepts 7 parameters: sexo, pesoKg, formula, alturaCm, idadeAnos, nivelAtividade, percentualGorduraCorporal. Required: sexo, pesoKg, formula, alturaCm, idadeAnos, nivelAtividade. The full parameter table on this page comes from the server's own tool schema.
Register the Contaí — Calculadoras Fiscais Brasileiras MCP server in PolicyLayer and add a rule for calcular_tmb: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Contaí — Calculadoras Fiscais Brasileiras. Nothing to install.
calcular_tmb is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the calcular_tmb rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for calcular_tmb. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
calcular_tmb is provided by the Contaí — Calculadoras Fiscais Brasileiras MCP server (@contai-evoluke/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
