vineflower

Modern FernFlower fork for Java bytecode decompilation.

Usage

Use Vineflower options followed by one or more Java bytecode inputs and an output directory. Run vineflower --help for the complete version-specific option list.

Example

{"args":["input.jar","decompiled"],"input_paths":["input.jar"],"output_paths":["decompiled"]}

MCP wrapper arguments

Every MCP wrapper for this command accepts:

• args: native command arguments, as an array of strings.
• workdir: optional host directory to mount as /work.
• input_paths: host input files/directories used for mount-root inference and path rewriting.
• output_paths: host output files/directories used for mount-root inference and path rewriting.
• extra_mounts: additional Docker mounts such as Android keys or persistent state.
• timeout_seconds: command timeout.
• docker_image: override the default stanislavpovolotsky/jddlab:latest image.
• interactive: add Docker -it; keep this false for most MCP clients.

The server runs:

docker run --rm -v "<host-mount-root>:/work" stanislavpovolotsky/jddlab:latest vineflower <args>
