WHAT IT DOES

What anim_set_loop does on Breakpoint

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

Parameter	Type	Required	Description
`mode`	string	Yes	Loop mode: none, linear, or pingpong
`name`	string	Yes	Animation name
`library`	string	—	Animation library name (default "")
`player_path`	string	Yes	AnimationPlayer node path

Parameters from the server's own tool schema.

RISK

Why anim_set_loop is rated Medium

This tool creates or modifies animation configuration data (loop mode) in a reversible manner. It does not execute external code, delete data irreversibly, or move money. The 'undoable' annotation demonstrates the modification can be reversed, placing it in the Write category rather than Destructive.

From the tool's definition Tool description explicitly states 'Set an Animation's loop mode (undoable)', indicating it modifies animation properties. The term 'undoable' confirms this is a reversible write operation, not a destructive action.

RECOMMENDED RULE

The rule that runs anim_set_loop safely

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

anim_set_loop Rate-limited

anim_set_loop 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.

        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about anim_set_loop

What does the anim_set_loop tool do? +

Set an Animation's loop mode (undoable). It is categorised as a Write tool in the Breakpoint MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does anim_set_loop accept? +

anim_set_loop accepts 4 parameters: mode, name, library, player_path. Required: mode, name, player_path. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on anim_set_loop? +

Register the Breakpoint MCP server in PolicyLayer and add a rule for anim_set_loop: 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 Breakpoint. Nothing to install.

What risk level is anim_set_loop? +

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

Can I rate-limit anim_set_loop? +

Yes. Add a rate_limit block to the anim_set_loop 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 anim_set_loop completely? +

Set action: deny in the PolicyLayer policy for anim_set_loop. 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 anim_set_loop? +

anim_set_loop is provided by the Breakpoint MCP server (breakpoint-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
