What calculate_kinetic_energy does on Calcgrid
AI agents call calculate_kinetic_energy to retrieve information from Calcgrid without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
mass_kg | number | Yes | Mass of the moving object in kilograms. Unit: kg. |
velocity_m_s | number | Yes | Speed in metres per second (km/h ÷ 3.6, mph × 0.44704). Limited to 10 % of the speed of light, below which the classical formula is accurate to within 1 %. Unit |
Parameters from the server's own tool schema.
Why calculate_kinetic_energy is rated Low
Even though calculate_kinetic_energy only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs calculate_kinetic_energy safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Calcgrid, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For calculate_kinetic_energy, this is the rule to start with:
calculate_kinetic_energy is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Calcgrid, apply this rule, and every calculate_kinetic_energy call is checked against it from then on.
Questions about calculate_kinetic_energy
Use this when you need the energy of motion of an object of known mass and speed (vehicle, projectile, ball), for example to compare impact or braking energies. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when rotation contributes significantly (rotational energy ½·I·ω² is not included), speeds approach the speed of light (relativistic formula needed), or you need energy from height (use potential-energy). What it computes: Computes the translational kinetic energy of a moving mass from KE = ½·m·v², reported in joules, kilojoules, kilowatt-hours and kilocalories. Inputs: mass_kg (number, kg); velocity_m_s (number, m/s). Complete JSON argument examples: {"mass_kg":1200,"velocity_m_s":25} | {"mass_kg":0.145,"velocity_m_s":40} Outputs: kinetic_energy_j [J], kinetic_energy_kj [kJ], kinetic_energy_kwh [kWh], kinetic_energy_kcal [kcal], velocity_km_h [km/h]. Formula: KE = ½ × mass_kg × velocity_m_s²; kJ = J / 1000; kWh = J / 3,600,000; kcal = J / 4184 Direct REST fallback: POST https://tttkmbb.com/api/v1/calculate/kinetic-energy with the same JSON input fields. Do not guess another /api/* path. Docs: https://tttkmbb.com/physics/kinetic-energy.md. It is categorised as a Read tool in the Calcgrid MCP Server, which means it retrieves data without modifying state.
calculate_kinetic_energy accepts 2 parameters: mass_kg, velocity_m_s. Required: mass_kg, velocity_m_s. The full parameter table on this page comes from the server's own tool schema.
Register the Calcgrid MCP server in PolicyLayer and add a rule for calculate_kinetic_energy: 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 Calcgrid. Nothing to install.
calculate_kinetic_energy 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 calculate_kinetic_energy 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 calculate_kinetic_energy. 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.
calculate_kinetic_energy is provided by the Calcgrid MCP server (https://tttkmbb.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
