AI agents call get_note_paths to retrieve information from Zk without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves or queries note path data from a local knowledge base with no indication of side effects, modification, or execution capabilities. This is a read operation that fits the Read category. Severity is low because accessing note paths poses minimal security risk—it is informational data from a local system with no destructive or financial implications.
From the tool's definition Tool name 'get_note_paths' and context of sibling tools (get_note, get_tags, search functionality) indicate this retrieves path information from a zk note-taking system.
Attacks that exploit this kind of access
get_note_paths. It is categorised as a Read tool in the Zk MCP Server, which means it retrieves data without modifying state.
Register the Zk MCP server in PolicyLayer and add a rule for get_note_paths: 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 Zk. Nothing to install.
get_note_paths 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 get_note_paths 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 get_note_paths. 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.
get_note_paths is provided by the Zk MCP server (koei-kaji/zk-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
