WHAT IT DOES

What render_comp_range does on Ae

AI agents use render_comp_range 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
`reuse`	boolean	—	Ask aerender to reuse the running AE instance. Defaults to false.
`verbose`	string	—	Optional verbose flag, e.g. ERRORS or ERRORS_AND_PROGRESS.
`compName`	string	Yes	Composition name to render.
`endFrame`	number	—	Optional end frame.
`timeoutMs`	number	—	Process timeout in milliseconds. Defaults to 1800000.
`outputPath`	string	Yes	Absolute output path.
`startFrame`	number	—	Optional start frame.
`projectPath`	string	Yes	Absolute path to an .aep file.
`outputModule`	string	—	Optional output module template name.
`frameIncrement`	number	—	Optional frame increment.
`renderSettings`	string	—	Optional render settings template name.

Parameters from the server's own tool schema.

RISK

Why render_comp_range is rated Medium

An AI agent can call render_comp_range 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 render_comp_range 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 render_comp_range, this is the rule to start with:

render_comp_range Rate-limited

render_comp_range 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.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "render_comp_range": {

          "window": "minute",
          "max": 30,

        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about render_comp_range

What does the render_comp_range tool do? +

Render a composition frame range with aerender.exe for quick automated verification. 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 render_comp_range accept? +

render_comp_range accepts 11 parameters: reuse, verbose, compName, endFrame, timeoutMs, outputPath, startFrame, projectPath, outputModule, frameIncrement, renderSettings. Required: compName, outputPath, projectPath. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on render_comp_range? +

Register the Ae MCP server in PolicyLayer and add a rule for render_comp_range: 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 render_comp_range? +

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

Can I rate-limit render_comp_range? +

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

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

render_comp_range 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.
