Calculate Shannon entropy for a region of data. Entropy measures randomness/information density (0-8 bits/byte). High entropy indicates compressed/encrypted data, low entropy indicates structured/repetitive data. Useful for detecting encryption, compression, or analyzing data randomness.
AI agents call imhex_data_entropy to retrieve information from ImHex MCP Integration without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
imhex_data_entropy performs passive analysis and measurement of data properties. It queries/analyzes binary data to compute a statistical metric (Shannon entropy) without changing the underlying file, executing code, or triggering external operations. This is a classic Read operation—information retrieval with no side effects.
From the tool's definition Tool description states it 'Calculate[s] Shannon entropy for a region of data' with the explicit purpose of 'detecting encryption, compression, or analyzing data randomness'.
Documented attack patterns abuse exactly the kind of access imhex_data_entropy gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ImHex MCP Integration, and nothing reaches the server without passing your rules. This is the rule we recommend for imhex_data_entropy:
{
"version": "1",
"default": "deny",
"tools": {
"imhex_data_entropy": {}
}
}imhex_data_entropy is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Calculate Shannon entropy for a region of data. Entropy measures randomness/information density (0-8 bits/byte). High entropy indicates compressed/encrypted data, low entropy indicates structured/repetitive data. Useful for detecting encryption, compression, or analyzing data randomness. It is categorised as a Read tool in the ImHex MCP Integration MCP Server, which means it retrieves data without modifying state.
Register the ImHex MCP Integration MCP server in PolicyLayer and add a rule for imhex_data_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 ImHex MCP Integration. Nothing to install.
imhex_data_entropy is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the imhex_data_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.
Set action: deny in the PolicyLayer policy for imhex_data_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.
imhex_data_entropy is provided by the ImHex MCP Integration MCP server (jmpnop/imhexmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from ImHex MCP Integration, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
