Language Coverage

Tech Debt MCP analyzes 14 languages for code-quality issues and 10 package ecosystems for offline dependency inventory.

Code analyzers

Language	Analyzer	Notes
TypeScript	typescriptAnalyzer.ts	Strict-mode awareness, any/@ts-ignore/as any detection.
JavaScript	javascriptAnalyzer.ts	Shared base with TS; ES module + CJS support.
Python	pythonAnalyzer.ts	PEP 8 hints, print() left in code, broad except blocks.
Java	javaAnalyzer.ts	TODO/FIXME, exception swallowing, magic numbers.
Kotlin	kotlinAnalyzer.ts	Nullability hints, !! operator misuse.
Swift	swiftAnalyzer.ts (+ SwiftUI Phase 1/2 checks)	Force-unwraps, print(), SwiftUI-specific patterns.
Objective-C	objectivecAnalyzer.ts	Memory-management hints, NSLog leakage.
Go	goAnalyzer.ts	Empty error returns, fmt.Println in production paths.
Rust	rustAnalyzer.ts	unwrap()/expect() overuse, dbg! left in code.
Ruby	rubyAnalyzer.ts	puts in production code, rescue Exception antipattern.
PHP	phpAnalyzer.ts	var_dump/die debugging leftovers.
C#	csharpAnalyzer.ts	Console.WriteLine, empty catch blocks.
C++	cppAnalyzer.ts	printf in production paths, goto usage.
C	cAnalyzer.ts	Same family as C++; tuned for K&R idioms.

Every analyzer extends BaseAnalyzer and emits issues via checkPattern — see ARCHITECTURE.md for the full flow.

Dependency parsers

Ecosystem	Parser	Manifest files
npm	npmParser.ts	package.json, package-lock.json
pip	pipParser.ts	requirements.txt, Pipfile, pyproject.toml (Poetry)
Cargo	cargoParser.ts	Cargo.toml
Gradle	gradleParser.ts	build.gradle, build.gradle.kts
NuGet	nugetParser.ts	*.csproj, packages.config
Go modules	goModParser.ts	go.mod
Composer	composerParser.ts	composer.json
Bundler	bundlerParser.ts	Gemfile
SwiftPM	swiftPackageParser.ts	Package.swift
C/C++	cppParser.ts	vcpkg.json

All ecosystems flow through the same check_dependencies and get_vulnerability_report tools — see the tool reference.
