WHAT IT DOES

What start_rendering does on Aos

AI agents invoke start_rendering to trigger actions in Aos. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why start_rendering is rated High

Initiates render operations with unpredictable resource consumption and side effects.

From the tool's definition Start rendering queued jobs; triggers external render operations.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs start_rendering safely

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

start_rendering Rate-limited

start_rendering stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about start_rendering

What does the start_rendering tool do? +

Start rendering queued jobs. It is categorised as a Execute tool in the Aos MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on start_rendering? +

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

What risk level is start_rendering? +

start_rendering is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit start_rendering? +

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

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

start_rendering is provided by the Aos MCP server (@hybridlabor-api/aos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
