WHAT IT DOES

What addPhysicsBody does on Spline MCP Server

AI agents use addPhysicsBody to create or update resources in Spline MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Spline MCP Server environment.

RISK

Why addPhysicsBody is rated Medium

This tool creates a new physics body object within a Spline scene, which is a Write-category operation: it modifies the 3D design state reversibly and can be undone. It is not Destructive (no irreversible deletion), not Execute (does not run arbitrary code or external operations with data-dependent effects), and not Read (creates rather than retrieves).

From the tool's definition Tool name 'addPhysicsBody' indicates creation of a new physics body object in the Spline 3D design environment. Sibling tools like 'addCamera', 'addDirectionalLight', and 'addMaterialLayer' all use the 'add*' prefix pattern and create/modify scene objects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs addPhysicsBody safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Spline MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For addPhysicsBody, this is the rule to start with:

addPhysicsBody Rate-limited

addPhysicsBody 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Spline MCP Server, apply this rule, and every addPhysicsBody call is checked against it from then on.

FAQ

Questions about addPhysicsBody

What does the addPhysicsBody tool do? +

addPhysicsBody is a write tool on the Spline MCP Server MCP server. It is categorised as a Write tool in the Spline MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on addPhysicsBody? +

Register the Spline MCP Server MCP server in PolicyLayer and add a rule for addPhysicsBody: 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 Spline MCP Server. Nothing to install.

What risk level is addPhysicsBody? +

addPhysicsBody is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit addPhysicsBody? +

Yes. Add a rate_limit block to the addPhysicsBody 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.

How do I block addPhysicsBody completely? +

Set action: deny in the PolicyLayer policy for addPhysicsBody. 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.

What MCP server provides addPhysicsBody? +

addPhysicsBody is provided by the Spline MCP Server MCP server (aydinfer/spline-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
