What enable_entropy_filter does on Enhanced Knowledge Graph Memory Server
AI agents use enable_entropy_filter to create or update resources in Enhanced Knowledge Graph Memory Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Enhanced Knowledge Graph Memory Server environment.
Why enable_entropy_filter is rated Medium
This tool configures a filtering mechanism that affects which memories are retained or dropped during consolidation. While it does not permanently delete data (entropy filtering happens during consolidation, likely with recoverability), it modifies the system's behavior in a way that results in selective data being processed differently. This is a Write operation (configuration/state modification) rather than Read.
From the tool's definition Tool description states it "Enable[s] or disable[s] the Shannon entropy gate that drops low-information memories during consolidation" — this modifies the filtering/processing behavior of stored memories, which constitutes a reversible configuration change to…
Attacks that exploit this kind of access
The rule that runs enable_entropy_filter 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 enable_entropy_filter, this is the rule to start with:
enable_entropy_filter stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Enhanced Knowledge Graph Memory Server, apply this rule, and every enable_entropy_filter call is checked against it from then on.
Questions about enable_entropy_filter
Enable or disable the Shannon entropy gate that drops low-information memories during consolidation. It is categorised as a Write tool in the Enhanced Knowledge Graph Memory Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Enhanced Knowledge Graph Memory Server MCP server in PolicyLayer and add a rule for enable_entropy_filter: 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.
enable_entropy_filter is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the enable_entropy_filter 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 enable_entropy_filter. 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.
enable_entropy_filter 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.
