Compare two files side-by-side (compares up to 1MB for similarity)
AI agents call imhex_compare_files 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.
This tool retrieves and analyzes file data to produce a comparison report. It performs no write operations, does not execute code or commands, does not delete data, and has no financial impact. While used in a reverse engineering context (binary analysis, malware inspection), the tool itself is purely informational—it reads file contents and outputs similarity metrics.
From the tool's definition Tool description states it "Compare[s] two files side-by-side" with no mention of modification, deletion, or execution. The 1MB limit and comparison operation are read-only analysis functions.
Documented attack patterns abuse exactly the kind of access imhex_compare_files 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_compare_files:
{
"version": "1",
"default": "deny",
"tools": {
"imhex_compare_files": {}
}
}imhex_compare_files is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Compare two files side-by-side (compares up to 1MB for similarity). 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_compare_files: 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_compare_files 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_compare_files 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_compare_files. 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_compare_files 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.
Free to start. No card required.
