WHAT IT DOES

What anim_statemachine_add_transition does on Breakpoint

AI agents use anim_statemachine_add_transition 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
`priority`	integer	—	Transition priority (lower wins when multiple are valid)
`to_state`	string	Yes	Destination state name (or "End")
`tree_path`	string	Yes	AnimationTree node path relative to the scene root
`from_state`	string	Yes	Source state name (or "Start")
`xfade_time`	number	—	Cross-fade time in seconds (default 0)
`switch_mode`	string	—	Switch mode (default immediate)
`advance_mode`	string	—	Advance mode (default enabled)
`state_machine`	string	—	Name of a nested AnimationNodeStateMachine node within tree_root; omit to target tree_root itself
`advance_condition`	string	—	Advance condition parameter name (used with advance_mode auto)

Parameters from the server's own tool schema.

RISK

Why anim_statemachine_add_transition is rated Medium

This tool creates or modifies animation state machine transitions, which is a reversible data modification operation (Write category). It is not destructive since changes are undoable, not a read operation since it alters state, not financial, and not code execution in the dangerous sense.

From the tool's definition Tool description explicitly states it "Add[s] a transition" and is "undoable", indicating reversible modification of animation state machine data structures.

RECOMMENDED RULE

The rule that runs anim_statemachine_add_transition 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_statemachine_add_transition, this is the rule to start with:

anim_statemachine_add_transition Rate-limited

anim_statemachine_add_transition 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.

FAQ

Questions about anim_statemachine_add_transition

What does the anim_statemachine_add_transition tool do? +

Add a transition between two states in an AnimationNodeStateMachine (undoable). from_state/to_state must exist (or be the built-in "Start"/"End"). switch_mode: immediate|sync|at_end; advance_mode: disabled|enabled|auto. 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_statemachine_add_transition accept? +

anim_statemachine_add_transition accepts 9 parameters: priority, to_state, tree_path, from_state, xfade_time, switch_mode, advance_mode, state_machine, advance_condition. Required: to_state, tree_path, from_state. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on anim_statemachine_add_transition? +

Register the Breakpoint MCP server in PolicyLayer and add a rule for anim_statemachine_add_transition: 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_statemachine_add_transition? +

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

Can I rate-limit anim_statemachine_add_transition? +

Yes. Add a rate_limit block to the anim_statemachine_add_transition 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_statemachine_add_transition completely? +

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

anim_statemachine_add_transition 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.
