MCP Java Dev Tools bridges agentic coding tools and live Java runtime behavior through a lightweight sidecar agent.

Static analysis only gets you so far. By attaching directly to a running JVM, this tool surfaces bytecode-level runtime signals that static analysis alone can't see — enabling probe-verified inspection, targeted regression checks, runtime-path validation, and deterministic debugging workflows.

The runtime agent is built with ByteBuddy and works alongside JDWP rather than replacing it. On top of the probe layer, the system adds framework-aware data synthesis and strict, fail-closed tool contracts — so agent orchestrators can make decisions grounded in actual runtime proof, not inference.

The current focus is HTTP entrypoints. Non-HTTP protocol support is on the horizon but not yet implemented — it will need concrete models and validation targets before the core contracts can be generalized.

For operator workflows and end-to-end execution flows, see docs/how-it-works/README.md.
