Calculate cryptographic hashes for all open files simultaneously. Supports multiple hash algorithms (md5, sha1, sha256, etc.). Useful for generating hash manifests and file comparison.
AI agents call imhex_batch_hash 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.
Hashing is a read-only operation that computes a deterministic output from file contents without side effects. While the ImHex server enables reverse engineering workflows, this specific tool only retrieves hash digests for comparison and manifest purposes, making it a Read-category operation with low blast radius if misused by an AI agent.
From the tool's definition Tool calculates and retrieves cryptographic hash values from files; description states 'Calculate cryptographic hashes for all open files simultaneously' with support for multiple algorithms.
Documented attack patterns abuse exactly the kind of access imhex_batch_hash 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_batch_hash:
{
"version": "1",
"default": "deny",
"tools": {
"imhex_batch_hash": {}
}
}imhex_batch_hash is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Calculate cryptographic hashes for all open files simultaneously. Supports multiple hash algorithms (md5, sha1, sha256, etc.). Useful for generating hash manifests and file comparison. 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_batch_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.
imhex_batch_hash 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_batch_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.
Set action: deny in the PolicyLayer policy for imhex_batch_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.
imhex_batch_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.
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.
