How this service works
The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.
Output
Returns simulation output data including updated positions, orientations, velocities, and collision events for all bodies in the physics scene after the simulation step(s) are processed.
Example use cases
Game object collision detection
“I need to simulate two moving rigid body spheres colliding in 3D space using Rapier physics — can you run the simulation and tell me the resulting positions and velocities after the collision?”
Robotics arm motion modeling
“Can you run a physics simulation of a robotic arm with three rigid segments connected by revolute joints, applying a torque of 5 N·m to the base joint, and give me the end-effector position after 1 second?”
Falling object trajectory calculation
“Simulate a rigid cube dropped from a height of 10 meters under standard gravity using Rapier WASM physics and return its position and velocity at each 0.1-second interval until it hits the ground.”
Technical details
Endpoint
POSThttps://api.m2mcent.com/rapier-wasm-physics-mcp/api/processWhen to prefer
Choose this endpoint when you need server-side Rapier physics simulation without managing a local WASM runtime — ideal for agents that need to compute rigid body dynamics, collision detection, or constraint solving as part of a workflow without embedding a physics engine themselves.
Side effects
- Malformed or invalid physics scene data in the 'data' field returns a parsing or validation error
- Simulation with degenerate geometry (e.g. zero-volume shapes) may produce NaN or infinite values
- Overly complex scenes may exceed processing time limits and return a timeout error
- Missing required physics parameters may result in a default-value fallback or error response
