mcp-jdwp-java

Un complemento de depuración para programas Java que usa JDWP, el protocolo estándar con el que un depurador se comunica con una aplicación Java en ejecución. Permite examinar y controlar la ejecución del programa.

In plain words
What is it for?
Sirve para poner puntos de interrupción, inspeccionar el estado, evaluar expresiones, cambiar variables, detenerse cuando se lanza una excepción y seguir la ejecución con mensajes de registro.
Why use it?
Ayuda a investigar errores observando el estado real de la aplicación mientras corre, en vez de depender solo de registros o de volver a ejecutar el código a ciegas.

Security

Grade A, and why

mcp-jdwp-java scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Files

What ships with it

1 file beside marketplace.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
