navigate_memory · Zikkaron MCP: Risk & Policy

WHAT IT DOES

What navigate_memory does on Zikkaron

AI agents invoke navigate_memory to trigger actions in Zikkaron. 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.

WHY IT NEEDS A POLICY

Why navigate_memory needs a policy

navigate_memory triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Verdict

navigate_memory Rate-limited

navigate_memory 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 navigate_memory

What does the navigate_memory tool do? +

Navigate concept space using Successor Representation cognitive maps. It is categorised as a Execute tool in the Zikkaron MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on navigate_memory? +

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

What risk level is navigate_memory? +

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

Can I rate-limit navigate_memory? +

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

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

navigate_memory is provided by the Zikkaron MCP server (pypi:zikkaron). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
