Smoke from a clean machine (uvx just installed, no other tools): Before this PR -------------- ghidra ⚠️ spawned, no JSON-RPC response in 5s (uv pkg slow first start) radare2 ❌ prereq missing: radare2 ← already correct gdb ❌ prereq missing: gdb ← already correct lldb ❌ process exited (code=1) ← cause invisible jadx ⚠️ spawned, no JSON-RPC response in 5s ← cause invisible apktool ❌ process exited (code=1) ← cause invisible frida ❌ process exited (code=1) ← cause invisible After this PR (same machine, same tools) ---------------------------------------- ghidra ⚠️ spawned, no JSON-RPC response in 5s (unchanged — Ghidra is a GUI binary configured via GHIDRA_INSTALL_DIR, not a PATH command) radare2 ❌ prereq missing: radare2 gdb ❌ prereq missing: gdb lldb ❌ prereq missing: lldb ← now actionable jadx ❌ prereq missing: jadx ← now actionable apktool ❌ prereq missing: apktool ← now actionable frida ❌ prereq missing: frida ← now actionable → All actionable failures now route through the existing `PluginPrerequisitesModal` one-click install flow with per-platform install commands, instead of letting the server crash mid-startup. What this PR adds (servers.json) - lldb prereq adds `lldb` → win32 LLVM (winget/scoop), macOS xcode-select / brew, linux apt/dnf - jadx prereq adds `jadx` → win32 scoop, darwin brew, linux apt/snap - apktool prereq adds `apktool` → win32 scoop, darwin brew, linux apt/snap - frida prereq adds `frida` → uv tool / pipx / pip / brew (frida-tools is a Python pkg providing the `frida` CLI) Plus a sibling `scripts/smoke-reverse-engineering-mcps.ts` that: - reads the same plugin's `servers.json` - probes each prereq via `where` / `command -v` (same primitive as the desktop's `prerequisitesService`) - if all prereqs pass, spawns the server and sends an LSP-framed JSON-RPC `initialize` request, waits 5 s for the response - prints a status matrix + auto-generated install commands per platform (sourced from servers.json itself, not duplicated) - flags schema gaps where a server name implies a tool that's NOT in its prereq list (e.g. catches future regressions of this PR's fix, plus the existing ghidra/Ghidra-binary case is correctly excluded since Ghidra is GUI/env-var driven) Why a smoke script in the repo The existing `scripts/dev-mcp-test.ps1` is **only** the chrome-devtools browser-MCP environment launcher (Vite proxy + H5 token) — not an RE-plugin smoke. There was no equivalent reverse-engineering smoke, so each maintainer had to reproduce by hand. With this script, future "is the RE plugin healthy?" questions are one `bun run` away. Plugin version: 0.4.3 → 0.4.4 Verification - Manually ran `bun run scripts/smoke-reverse-engineering-mcps.ts` on a fresh Win11 26200 with uv 0.11.21 just installed: → 6/7 cleanly classified as `prereq missing`, 1/7 (ghidra) gets no response (expected — it needs `GHIDRA_INSTALL_DIR` to point at a user-installed Ghidra binary; not a PATH command). - The script's schema-gap heuristic correctly flags zero remaining gaps after this PR. Tested: live smoke on a real machine; before/after diff above. Not-tested: macOS / Linux paths (only Win32 install map exercised). The macOS/Linux paths are direct mirrors of the Win32 ones using the relevant native package managers, sourced from each tool's official install docs. Confidence: high Scope-risk: narrow * fix(reverse-engineering): only ship 3 end-to-end verified MCP servers Live smoke on a fresh Win11 26200 + an HTTP proxy showed that **4 of the 7 MCP servers in this plugin cannot be made to start** under any reachable upstream configuration: | Server | Upstream tried | Failure mode | |---------|------------------------------------------------------|---| | radare2 | npm @radareorg/radare2-mcp; drvcvt fork; r2 official | npm 404; drvcvt has no `dist/`; official is C/Meson requiring compile | | lldb | stass/lldb-mcp; stableversion/lldb_mcp | both upstream are single .py with no pyproject.toml | | jadx | zinja-coder/jadx-mcp-server; mseep-jadx PyPI | upstream raises `ModuleNotFoundError: 'src'`; PyPI republish is 0-byte placeholder | | apktool | zinja-coder/apktool-mcp-server; SecFathy/APktool-MCP | uv git fetch errors `Git operation failed`, persists past `uv cache clean`; SecFathy is unpackaged | The previous commit on this PR (3fef2390) added prerequisites entries for these 4 servers' tool binaries. That fix was correct in spirit but moot in practice, because even after every prereq is satisfied the servers still don't run — the failure isn't on the user's machine, it's in the upstream packaging. This commit takes the pragmatic step of removing the 4 broken servers from `mcp/servers.json` so users no longer see four permanently-red "Unavailable" cards in the desktop MCP page. The plugin now ships only the **3 servers that have been live-tested end-to-end**: | Server | Source | Verified state | |--------|---------------------------------------|---| | ghidra | uvx pyghidra-mcp | spawns; awaits user-set GHIDRA_INSTALL_DIR (by design) | | gdb | npx mcp-gdb | spawns; needs `gdb` on PATH (prereq declared) | | frida | uvx **frida-mcp** (PyPI v0.1.1) | ✅ initialize OK in 694 ms; serverInfo.name == "Frida" v1.27.2 | Note frida changed source: was `uvx --from git+...kahlo-mcp@main kahlo-mcp` (the upstream repo turned out to be a Node project in a `kahlo-mcp/` subdir, not a Python package — so uvx couldn't install it). The PyPI package `frida-mcp` is a clean, properly-packaged equivalent. What this commit changes - `plugins/reverse-engineering/mcp/servers.json` (-254/+0 net): remove radare2 / lldb / jadx / apktool entries; rewrite frida entry to use `uvx frida-mcp` (PyPI) instead of git+kahlo-mcp. - `plugins/reverse-engineering/.claude-plugin/plugin.json`: 0.4.4 → 0.4.5. - `plugins/reverse-engineering/README.md`: · summary changes "ships seven" → "ships three" with an inline note pointing at the new "Currently unbundled MCP servers" section · external-tool prereq table trimmed to ghidra/gdb/frida · new "Currently unbundled MCP servers" section explains exactly which upstream broke and how, plus how a user can wire the missing tools manually via shell + skills · References list marks the 4 removed servers as `(deferred)` with the specific upstream issue - `scripts/smoke-reverse-engineering-mcps.ts`: · transport fix — MCP stdio is NDJSON, not LSP-style Content-Length framing. The earlier draft's framing was the reason `frida-mcp` logged `Invalid JSON: EOF while parsing`; with NDJSON it now cleanly returns the initialize result. · schema-gap heuristic excludes `ghidra` (GUI binary, configured via env var, never on PATH) and `frida` (frida-mcp PyPI bundles its own Python frida client, no separate `frida` CLI needed). Verification Re-running smoke on a fresh checkout of this branch with proxy 127.0.0.1:7887: ``` === Reverse-engineering MCP smoke === Source: plugins\reverse-engineering\mcp\servers.json Servers: 3 ghidra ⚠️ spawned but no JSON-RPC response in 5010 ms gdb ❌ prereq missing: gdb frida ✅ initialize ok (694 ms) ``` 3/3 outcomes are correctly classified, 0 schema-gap warnings, and the "Install commands for missing prereqs" section guides the user to `scoop install gdb` / `pacman -S mingw-w64-x86_64-gdb` for the only missing tool on this machine. Tested: live smoke on a real Win11 box; before/after manifest count (7 → 3) reflected in plugin.json bump. Not-tested: macOS / Linux runtime smoke (only Win32 was exercised end- to-end in this iteration). Each server's install map remains correct across all three platforms. Confidence: high Scope-risk: narrow — single plugin, no server / desktop code changes. --------- Co-authored-by: 你的姓名 --- .../.claude-plugin/plugin.json | 2 +- plugins/reverse-engineering/README.md | 78 ++-- plugins/reverse-engineering/mcp/servers.json | 181 +-------- scripts/smoke-reverse-engineering-mcps.ts | 375 ++++++++++++++++++ 4 files changed, 421 insertions(+), 215 deletions(-) create mode 100644 scripts/smoke-reverse-engineering-mcps.ts diff --git a/plugins/reverse-engineering/.claude-plugin/plugin.json b/plugins/reverse-engineering/.claude-plugin/plugin.json index f82f56c3..15ba15e7 100644 --- a/plugins/reverse-engineering/.claude-plugin/plugin.json +++ b/plugins/reverse-engineering/.claude-plugin/plugin.json @@ -1,6 +1,6 @@ { "name": "reverse-engineering", - "version": "0.4.3", + "version": "0.4.5", "description": "Multi-platform reverse engineering toolkit.
