# Ragdoll Joint Limits MCP

> Ragdoll Joint Limits MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.22/call, status unknown (last checked 2026-10-12).

Processes ragdoll joint limit data for physics simulations, returning constrained joint parameters for character animation systems.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ragdoll-joint-limits-mcp-f1f14e55 -d '<json body>'
```

Example prompt: Process the joint limit configuration for my ragdoll character — here's the joint data string: '{"spine":{"min":-30,"max":30},"knee":{"min":0,"max":140}}' — and return the constrained joint limits I can use in my physics simulation.

## When to prefer this

Choose this endpoint when you need to compute or validate joint angle limits for ragdoll physics simulations in game engines or animation pipelines, and require a paid, hosted API rather than running a local physics library. Particularly useful for agents automating character rig configuration or procedurally generating ragdoll constraints at scale.

## Known failure modes

- Invalid or malformed JSON in the data string field returns a processing error
- Empty data field causes a bad request response
- Joint values outside physically plausible ranges may return clamped or error results
- Payment failure via x402 protocol blocks the request entirely
- Malformed joint names or unrecognized skeleton hierarchy may return partial results

## 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 computed joint limit parameters, constrained angle ranges, and validated configuration values that can be directly applied to a ragdoll physics simulation or character animation system.
