electron_verify_integrity
Verify Electron ASAR integrity: parse the ElectronAsarIntegrity JSON embedded in the main binary, locate each referenced ASAR, and compare the on-disk SHA256/SHA512 hash against the embedded hash. A mismatch means the ASAR was tampered with after build.

What electron_verify_integrity does on Jshookmcp
AI agents call electron_verify_integrity to retrieve information from Jshookmcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why electron_verify_integrity is rated Low
Tool only reads and verifies file integrity; performs no modifications or side effects.
From the tool's definition Verify, parse, compare hash, detect tampering—no modification.
Attacks that exploit this kind of access
The rule that runs electron_verify_integrity safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Jshookmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For electron_verify_integrity, this is the rule to start with:
electron_verify_integrity is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Jshookmcp, apply this rule, and every electron_verify_integrity call is checked against it from then on.
Questions about electron_verify_integrity
Verify Electron ASAR integrity: parse the ElectronAsarIntegrity JSON embedded in the main binary, locate each referenced ASAR, and compare the on-disk SHA256/SHA512 hash against the embedded hash. A mismatch means the ASAR was tampered with after build. It is categorised as a Read tool in the Jshookmcp MCP Server, which means it retrieves data without modifying state.
Register the Jshook MCP server in PolicyLayer and add a rule for electron_verify_integrity: 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 Jshookmcp. Nothing to install.
electron_verify_integrity 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 electron_verify_integrity 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 electron_verify_integrity. 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.
electron_verify_integrity is provided by the Jshook MCP server (@jshookmcp/jshook). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
