THE RISK

Why imhex_hash needs a policy

Hashing is a deterministic read operation that computes a digest of data without altering the file, executing arbitrary code, deleting content, or moving money. The tool merely retrieves and processes data already present in memory. Although the broader ImHex server enables reverse engineering workflows, this specific tool is limited to non-destructive analysis.

From the tool's definition Tool name 'imhex_hash' and description 'Calculate hash of data in the currently open file' — the operation is a read-only cryptographic computation performed on existing file data with no modification or side effects.

POLICY

How to control imhex_hash

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_hash:

policy.json

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

imhex_hash is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register ImHex MCP Integration — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about imhex_hash

What does the imhex_hash tool do? +

Calculate hash of data in the currently open file. It is categorised as a Read tool in the ImHex MCP Integration MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on imhex_hash? +

Register the ImHex MCP Integration MCP server in PolicyLayer and add a rule for imhex_hash: 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.

What risk level is imhex_hash? +

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

Can I rate-limit imhex_hash? +

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

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

imhex_hash 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.

Enforce policy on every ImHex MCP Integration tool call.

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.
