WHAT IT DOES

What submit_job does on Libi

AI agents invoke submit_job to trigger actions in Libi. 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 submit_job is rated High

Submits a job for execution; 'fal mirror' implies running external AI/compute operations.

From the tool's definition Test-mode fal mirror

RECOMMENDED RULE

The rule that runs submit_job safely

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

submit_job Rate-limited

submit_job 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.

FAQ

Questions about submit_job

Test-mode fal mirror. It is categorised as a Execute tool in the Libi MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on submit_job? +

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

What risk level is submit_job? +

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

Can I rate-limit submit_job? +

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

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