process_enqueue_task · Promethean OS MCP: Risk & Policy

WHAT IT DOES

What process_enqueue_task does on Promethean OS MCP

AI agents invoke process_enqueue_task to trigger actions in Promethean OS MCP. 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.

WHY IT NEEDS A POLICY

Why process_enqueue_task needs a policy

The tool explicitly enqueues commands for execution, which falls under the Execute category. While it adds concurrency limiting (queue semantics), the fundamental action is running commands. Given the server also has exec_run and shell execution capabilities, these queued commands are likely shell/system commands.

From the tool's definition 'Enqueue a command for execution' — the tool queues commands for execution, triggering external operations

Verdict

process_enqueue_task Rate-limited

process_enqueue_task 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Promethean OS MCP, so you can run agents against it safely.

FAQ

Questions about process_enqueue_task

What does the process_enqueue_task tool do? +

Enqueue a command for execution respecting concurrency limits. It is categorised as a Execute tool in the Promethean OS MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on process_enqueue_task? +

Register the Promethean OS MCP server in PolicyLayer and add a rule for process_enqueue_task: 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 Promethean OS MCP. Nothing to install.

What risk level is process_enqueue_task? +

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

Can I rate-limit process_enqueue_task? +

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

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

process_enqueue_task is provided by the Promethean OS MCP server (octave-commons/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
