What clear_heuristics does on Enhanced Knowledge Graph Memory Server
AI agents call clear_heuristics to permanently remove resources in Enhanced Knowledge Graph Memory Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why clear_heuristics is rated Critical
This tool irreversibly deletes all heuristics from the knowledge graph system without apparent filtering or recovery mechanism. The use of 'Drop' language and the blanket ('every') scope classify it as Destructive rather than Write. High severity due to potential loss of important stored heuristics that guide the system's behavior, with broad blast radius affecting all entities.
From the tool's definition Tool name 'clear_heuristics' combined with description 'Drop every heuristic (across all entities of type' uses the verb 'Drop', which in data management contexts typically means irreversible deletion.

The rule that runs clear_heuristics safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Enhanced Knowledge Graph Memory Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For clear_heuristics, this is the rule to start with:
clear_heuristics is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Enhanced Knowledge Graph Memory Server, apply this rule, and every clear_heuristics call is checked against it from then on.
Questions about clear_heuristics
v2.1.0 \u2014 Drop every heuristic (across all entities of type. It is categorised as a Destructive tool in the Enhanced Knowledge Graph Memory Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Enhanced Knowledge Graph Memory Server MCP server in PolicyLayer and add a rule for clear_heuristics: 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 Enhanced Knowledge Graph Memory Server. Nothing to install.
clear_heuristics is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the clear_heuristics 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 clear_heuristics. 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.
clear_heuristics is provided by the Enhanced Knowledge Graph Memory Server MCP server (danielsimonjr/memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
