WHAT IT DOES

What split_layer does on Ae

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

Parameter	Type	Required	Description
`save`	boolean	—
`compName`	string	Yes
`layerName`	string	Yes
`splitTime`	number	—	Time in seconds to split at. Defaults to current time.
`timeoutMs`	number	—
`projectPath`	string	—

Parameters from the server's own tool schema.

RISK

Why split_layer is rated Medium

An AI agent can call split_layer faster than any human can review: one bad instruction and it creates or modifies resources in Ae by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs split_layer safely

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

split_layer Rate-limited

split_layer 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 Ae, apply this rule, and every split_layer call is checked against it from then on.

FAQ

Questions about split_layer

What does the split_layer tool do? +

Split a layer at a given time, producing two layers (like Ctrl+Shift+D). It is categorised as a Write tool in the Ae MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does split_layer accept? +

split_layer accepts 6 parameters: save, compName, layerName, splitTime, timeoutMs, projectPath. Required: compName, layerName. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on split_layer? +

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

What risk level is split_layer? +

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

Can I rate-limit split_layer? +

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

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

split_layer is provided by the Ae MCP server (@synthetic-ai/ae-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
