Detect file type based on magic number signatures. Identifies executables (PE, ELF, Mach-O), archives (ZIP, RAR, TAR), images (JPEG, PNG, GIF), documents (PDF, DOC), media files (MP3, MP4), and more. Returns all matching signatures with confidence levels.
AI agents call imhex_data_magic 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 only queries and identifies file characteristics without modifying, executing, or deleting any data. It is a passive analysis function that retrieves metadata about file types. The blast radius of misuse is minimal—an AI agent cannot cause harm by incorrectly identifying file types, only receive inaccurate information.
From the tool's definition Tool performs file type detection by analyzing magic number signatures and returns matching signatures with confidence levels.
Documented attack patterns abuse exactly the kind of access imhex_data_magic 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_magic:
{
"version": "1",
"default": "deny",
"tools": {
"imhex_data_magic": {}
}
}imhex_data_magic is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Detect file type based on magic number signatures. Identifies executables (PE, ELF, Mach-O), archives (ZIP, RAR, TAR), images (JPEG, PNG, GIF), documents (PDF, DOC), media files (MP3, MP4), and more. Returns all matching signatures with confidence levels. 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_magic: 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_magic 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_magic 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_magic. 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_magic 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.
