# enable_entropy_filter Enable or disable the Shannon entropy gate that drops low-information memories during consolidation Agent View of the PolicyLayer registry record for `enable_entropy_filter`. HTML page: https://policylayer.com/tools/danielsimonjr-memory-mcp/enable-entropy-filter ## Facts - Tool: `enable_entropy_filter` - Server: Enhanced Knowledge Graph Memory Server (`danielsimonjr/memory-mcp`) — https://policylayer.com/tools/danielsimonjr-memory-mcp.md - Homepage: https://github.com/danielsimonjr/memory-mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "enable_entropy_filter", "arguments": {} } } ``` ## 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 own 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…" ## Use case 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. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
