javadc

javadc is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from idachev/mcp-javadc. Its token cost is not measured, scanned A, original, ISC.

A local tool for decompiling Java programs, which means turning compiled Java files back into readable source-like code.

In plain words
What is it for?
Use it to examine compiled Java applications or libraries during debugging, analysis, or maintenance.
Why use it?
It helps inspect the behavior of Java software when the original source code is unavailable.

Written for no agent in particular: it speaks MCP, so any client can run it. Also seen: listed in a Claude config.

One of 3 entries in .mcp.json upstream. Installing this one merges just its entry into your config; the other 2 are separate, each on its own page.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

javadc 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 8d ago.

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.

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.
