JS Reverse Strong MCP
Standardizes front-end JavaScript reverse engineering workflows by providing tools for browser observation, runtime sampling, hooking, debugging, network analysis, and local environment reproduction.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

15 runtime dependencies (33 dev), 2 flagged: puppeteer-extra, puppeteer-extra-plugin-stealth
All four hints declared on every tool
85/85 tools missing one or more hints — deobfuscate_code (missing: destructiveHint, idempotentHint, openWorldHint); understand_code (missing: destructiveHint, idempotentHint, openWorldHint); summarize_code (missing: destructiveHint, idempotentHint, openWorldHint), +82 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool test coverage
Only 21/85 tools referenced in tests (25%)
Write tests that reference each tool by name so every tool has at least one test.
No eval / new Function
9 eval() or new Function() calls — dynamic code execution
Replace eval / Function with explicit parsing or safer alternatives.
Production dependencies are patched
1 critical, 10 high severity in production deps — sm-crypto@0.4.0 (critical), axios@1.13.5 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
4 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
3/15 production deps abandoned (no release in 2+ years): puppeteer-extra@2023-03-01 (3.5y), puppeteer-extra-plugin-stealth@2023-04-11 (3.4y), xbogus@2023-12-23 (2.7y)
