Automatically rig a 3D character model for animation using Meshy AI. Creates a skeletal rig for character models, enabling them to be animated. Rigging INCLUDES free walking + running animations. IMPORTANT: The source model should be generated with pose_mode=
AI agents use meshy_rig to create or update resources in Meshy MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Meshy MCP Server environment.
This tool creates a new skeletal rig on an existing 3D model, which is a Write operation — it modifies/augments the model with a rig structure. It does not execute code, delete data, or involve financial transactions. The blast radius is medium since misuse could generate unwanted rigs on models, consuming API credits and potentially overwriting model state, but effects are generally reversible.

Documented attack patterns abuse exactly the kind of access meshy_rig gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Meshy MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for meshy_rig:
{
"version": "1",
"default": "deny",
"tools": {
"meshy_rig": {
"limits": [
{
"counter": "meshy_rig_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}meshy_rig stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Automatically rig a 3D character model for animation using Meshy AI. Creates a skeletal rig for character models, enabling them to be animated. Rigging INCLUDES free walking + running animations. IMPORTANT: The source model should be generated with pose_mode=. It is categorised as a Write tool in the Meshy MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Meshy MCP Server MCP server in PolicyLayer and add a rule for meshy_rig: 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 Meshy MCP Server. Nothing to install.
meshy_rig is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the meshy_rig 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 meshy_rig. 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.
meshy_rig is provided by the Meshy MCP Server MCP server (meshy-dev/meshy-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Meshy MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
