WHAT IT DOES

What compute_entropy does on Enhanced Knowledge Graph Memory Server

AI agents call compute_entropy to retrieve information from Enhanced Knowledge Graph Memory Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why compute_entropy is rated Low

Computing entropy is a read-only statistical analysis that retrieves a derived metric from input text. It has no side effects, does not modify state, and does not execute external code or operations. The most severe applicable category is Read.

From the tool's definition Tool computes Shannon entropy of text strings—a mathematical operation on data that produces a statistic. No data is modified, deleted, or executed. The operation is purely analytical/mathematical.

RECOMMENDED RULE

The rule that runs compute_entropy 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 compute_entropy, this is the rule to start with:

compute_entropy Allowed

compute_entropy is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "compute_entropy": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Enhanced Knowledge Graph Memory Server, apply this rule, and every compute_entropy call is checked against it from then on.

FAQ

Questions about compute_entropy

What does the compute_entropy tool do? +

Compute the Shannon entropy of a text string (in bits per character). It is categorised as a Read tool in the Enhanced Knowledge Graph Memory Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on compute_entropy? +

Register the Enhanced Knowledge Graph Memory Server MCP server in PolicyLayer and add a rule for compute_entropy: 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.

What risk level is compute_entropy? +

compute_entropy is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit compute_entropy? +

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

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

compute_entropy 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.
