Maven Decoder

L0· runs locally

Lets AI agents read the real source of any Maven dependency, decompiled from ~/.m2 or Central.

v1.3.2 · active · repository · website · descriptor JSON · versions

Runs on your machine: something must execute the package.Only local packages are published (npm, PyPI, OCI, …). The registry never executes them, so tools are unknown until you run it.

Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.
