WHAT IT DOES

What emit_variant_plan does on 0sec

AI agents use emit_variant_plan to create or update resources in 0sec, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 0sec environment.

RISK

Why emit_variant_plan is rated Medium

An AI agent can call emit_variant_plan faster than any human can review: one bad instruction and it creates or modifies resources in 0sec by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs emit_variant_plan safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 0sec, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For emit_variant_plan, this is the rule to start with:

emit_variant_plan Rate-limited

emit_variant_plan 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.

What risk level is emit_variant_plan? +

Can I rate-limit emit_variant_plan? +

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

Set action: deny in the PolicyLayer policy for emit_variant_plan. 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.
