Manage cron jobs on a node. List, add, or remove scheduled tasks.
AI agents invoke omniwire_cron to trigger actions in OmniWire. 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.
Cron job management allows creating scheduled tasks that execute arbitrary commands on remote nodes. Adding a cron job is an Execute-level action because it schedules future command execution on infrastructure. Removing jobs is also significant.
From the tool's definition Manage cron jobs on a node. List, add, or remove scheduled tasks.
Documented attack patterns abuse exactly the kind of access omniwire_cron gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OmniWire, and nothing reaches the server without passing your rules. This is the rule we recommend for omniwire_cron:
{
"version": "1",
"default": "deny",
"tools": {
"omniwire_cron": {
"limits": [
{
"counter": "omniwire_cron_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}omniwire_cron 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.
Free to start. No card required.
Manage cron jobs on a node. List, add, or remove scheduled tasks. It is categorised as a Execute tool in the OmniWire MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the OmniWire MCP server in PolicyLayer and add a rule for omniwire_cron: 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 OmniWire. Nothing to install.
omniwire_cron is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the omniwire_cron 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.
Set action: deny in the PolicyLayer policy for omniwire_cron. 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.
omniwire_cron is provided by the OmniWire MCP server (voidchecksum/omniwire). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OmniWire, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
