Decompile a Java class from Maven dependency JARs into readable Java source code using the Vineflower decompiler. IMPORTANT: This tool works ONLY with classes from Maven dependencies (external libraries listed in pom.xml), NOT the project\
AI agents call decompile_class to retrieve information from Java Inspector without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and decompiles class files from Maven JARs into source code. It is purely a read/retrieval operation with no side effects — it does not modify, delete, execute, or create any data. The decompilation produces a human-readable representation of existing bytecode.

Decompile a Java class from Maven dependency JARs into readable Java source code using the Vineflower decompiler. IMPORTANT: This tool works ONLY with classes from Maven dependencies (external libraries listed in pom.xml), NOT the project\. It is categorised as a Read tool in the Java Inspector MCP Server, which means it retrieves data without modifying state.
Register the Java Inspector MCP server in PolicyLayer and add a rule for decompile_class: 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 Java Inspector. Nothing to install.
decompile_class 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 decompile_class 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 decompile_class. 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.
decompile_class is provided by the Java Inspector MCP server (mustafagoksever/java-inspector). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
