Read the last N lines of a log file on a node.
AI agents call omniwire_tail_log to retrieve information from OmniWire without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves log data from a node without modifying, deleting, or executing any operations. It is a passive query operation that observes system state. The severity is low because reading logs poses minimal risk even if misused by an AI agent, as it only exposes potentially sensitive logs but does not alter system state or execute commands.
From the tool's definition Tool name contains 'tail_log' and description states 'Read the last N lines of a log file on a node.' The verb 'Read' and the read-only nature of tailing log files confirm this is a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access omniwire_tail_log 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_tail_log:
{
"version": "1",
"default": "deny",
"tools": {
"omniwire_tail_log": {}
}
}omniwire_tail_log is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Read the last N lines of a log file on a node. It is categorised as a Read tool in the OmniWire MCP Server, which means it retrieves data without modifying state.
Register the OmniWire MCP server in PolicyLayer and add a rule for omniwire_tail_log: 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_tail_log is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the omniwire_tail_log 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_tail_log. 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_tail_log 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.
