AI agents call pathrule_list_snapshots to retrieve information from Pathrule without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
List operations are inherently Read category—they query and retrieve information without side effects. The empty description reduces confidence slightly, but the naming convention is consistent with Read semantics. No evidence suggests this creates, modifies, deletes, or executes any operations.
From the tool's definition Tool name 'pathrule_list_snapshots' contains 'list', which is a classic Read operation that retrieves or enumerates existing data. The description is empty, but the name strongly suggests it returns a snapshot inventory without modification or deletion.

pathrule_list_snapshots. It is categorised as a Read tool in the Pathrule MCP Server, which means it retrieves data without modifying state.
Register the Pathrule MCP server in PolicyLayer and add a rule for pathrule_list_snapshots: 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 Pathrule. Nothing to install.
pathrule_list_snapshots 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 pathrule_list_snapshots 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 pathrule_list_snapshots. 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.
pathrule_list_snapshots is provided by the Pathrule MCP server (pathrule/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
