Exposes JADX's internal call graph and xref (cross-reference) APIs through MCP tool calls, enabling LLMs to follow method invocations and field accesses across the entire decompiled codebase. The JADX-MCP-Server translates incoming MCP requests into HTTP calls to the plugin's /xref endpoint, which queries JADX's JavaClass entity relationships and returns structured call chains. This allows AI models to understand data flow and dependency graphs without manual navigation.
Unique: Integrates JADX's native JavaClass entity xref APIs directly into MCP tool calls, providing real-time call graph traversal without requiring separate graph indexing or external analysis tools. The HTTP bridge pattern allows stateless queries against the running JADX instance.
vs alternatives: More accurate than regex-based xref tools because it uses JADX's semantic AST analysis; faster than manual code review because the AI can recursively follow chains in seconds rather than hours.
Exposes AndroidManifest.xml, strings.xml, layout files, and other Android resources through MCP tools that parse and return structured data about app permissions, entry points, and UI definitions. The JADX plugin extracts these resources from the APK's resource directory and serves them as JSON via HTTP endpoints, which the MCP server translates into tool responses. This enables LLMs to understand app capabilities, permissions, and potential attack surfaces without manual XML parsing.
Unique: Directly parses Android binary resource formats (compiled XML, resource tables) from the APK using JADX's resource extraction APIs, returning structured JSON instead of raw binary data. Avoids the need for separate tools like aapt or apktool.
vs alternatives: Faster than running aapt or apktool separately because resources are already extracted in JADX's memory; more integrated than web-based APK analyzers because it works offline within the reverse engineer's local environment.
Retrieves the complete source code of a specific method from the decompiled APK, including line numbers, parameter definitions, and return type information. The JADX plugin queries its JavaClass model to extract the method's source code and maps it back to the original line numbers in the decompiled file. This enables LLMs to analyze method implementations in detail and correlate them with other analysis results (e.g., xrefs, stack traces).
Unique: Extracts method source code directly from JADX's decompiled AST and maps it to line numbers in the decompiled file, enabling precise correlation with other analysis results. This is more accurate than string-based extraction because it uses semantic information.
vs alternatives: More accurate than manual code review because it retrieves the exact decompiled source; more useful than class-level analysis because it focuses on specific method implementations.
Extracts APK-level metadata including version information, build configuration, certificate details, and other manifest-level data. The JADX plugin accesses the APK's metadata through its resource extraction APIs and returns structured information about the app's build, signing, and configuration. This enables LLMs to understand the app's provenance, versioning, and build-time configuration without manual APK inspection.
Unique: Extracts APK metadata directly from the binary manifest and certificate structures using JADX's resource parsing, providing structured data without requiring separate tools like aapt or keytool.
vs alternatives: More convenient than running aapt or keytool separately because metadata is extracted in-process; more integrated than web-based APK analyzers because it works offline.
Provides direct access to Smali (Android bytecode) representations of methods when Java decompilation is incomplete, obfuscated, or fails. The JADX plugin exposes a /smali endpoint that returns the low-level bytecode instructions for a given method, allowing LLMs to analyze register operations, control flow, and API calls at the bytecode level. This is critical for analyzing heavily obfuscated or packed APKs where Java decompilation produces unreadable output.
Unique: Leverages JADX's built-in Smali generation engine (which reconstructs bytecode from the decompiled AST) to provide bytecode views without requiring separate apktool or baksmali invocations. Integrates seamlessly with the decompilation pipeline.
vs alternatives: More accurate than standalone Smali tools because it uses JADX's semantic understanding of the code; more convenient than manual apktool extraction because Smali is generated on-demand through MCP.
Orchestrates a workflow where the MCP server provides the LLM with code snippets, resource data, and xref information, enabling the AI to perform Static Application Security Testing (SAST) by identifying insecure API usage, hardcoded secrets, and vulnerable patterns. The system does not perform hardcoded pattern matching; instead, it gives the LLM full context (source code, permissions, entry points) and relies on the model's reasoning to identify vulnerabilities. This leverages the LLM's semantic understanding of security rather than regex-based rules.
Unique: Delegates vulnerability detection to the LLM's semantic reasoning rather than using hardcoded SAST rules. The system provides rich context (code, resources, xrefs) and lets the AI identify vulnerabilities based on understanding of security principles, enabling detection of novel or context-specific issues that rule-based tools miss.
vs alternatives: More flexible than traditional SAST tools (Checkmarx, Fortify) because it adapts to new vulnerability patterns without rule updates; more accurate than simple pattern matching because it understands code semantics and context.
Enables the LLM to suggest and execute renames for obfuscated classes, methods, and variables based on semantic analysis of their usage patterns and functionality. The MCP server provides a rename tool that the LLM can invoke with a class/method name and a suggested meaningful name; the JADX plugin applies the rename through its refactoring API and persists it to the project. This transforms obfuscated identifiers (e.g., class 'a', method 'b') into human-readable names (e.g., 'NetworkManager', 'sendAuthToken') based on AI reasoning about their purpose.
Unique: Integrates JADX's native refactoring engine with LLM-driven semantic analysis, allowing the AI to propose renames based on code behavior rather than pattern matching. The rename operation is atomic and updates all xrefs in the project automatically.
vs alternatives: More intelligent than automated deobfuscation tools (which use heuristics like string analysis) because it leverages the LLM's understanding of code semantics and context; more practical than manual renaming because the AI can suggest names for hundreds of obfuscated identifiers in seconds.
The JADX-MCP-Server (Python, built on FastMCP) acts as a protocol adapter that translates incoming MCP tool calls (JSON-RPC format) from LLM clients into HTTP requests to the JADX plugin's internal HTTP server (port 8650). Each tool call is stateless: the server extracts parameters, constructs an HTTP request, waits for the response, and returns the result to the LLM. This decouples the LLM client from the JADX plugin, allowing multiple clients to connect to the same plugin instance and enabling integration with any MCP-compatible LLM client.
Unique: Uses FastMCP framework to implement a lightweight protocol translator that converts MCP tool calls to HTTP without maintaining state or session context. The stateless design allows multiple concurrent clients and simplifies deployment.
vs alternatives: More flexible than direct JADX API integration because it decouples clients from the plugin; more standardized than custom HTTP clients because it uses the MCP protocol, enabling compatibility with any MCP-aware LLM client.
+4 more capabilities
Transforms Vitest's native test execution output into a machine-readable JSON or text format optimized for LLM parsing, eliminating verbose formatting and ANSI color codes that confuse language models. The reporter intercepts Vitest's test lifecycle hooks (onTestEnd, onFinish) and serializes results with consistent field ordering, normalized error messages, and hierarchical test suite structure to enable reliable downstream LLM analysis without preprocessing.
Unique: Purpose-built reporter that strips formatting noise and normalizes test output specifically for LLM token efficiency and parsing reliability, rather than human readability — uses compact field names, removes color codes, and orders fields predictably for consistent LLM tokenization
vs alternatives: Unlike default Vitest reporters (verbose, ANSI-formatted) or generic JSON reporters, this reporter optimizes output structure and verbosity specifically for LLM consumption, reducing context window usage and improving parse accuracy in AI agents
Organizes test results into a nested tree structure that mirrors the test file hierarchy and describe-block nesting, enabling LLMs to understand test organization and scope relationships. The reporter builds this hierarchy by tracking describe-block entry/exit events and associating individual test results with their parent suite context, preserving semantic relationships that flat test lists would lose.
Unique: Preserves and exposes Vitest's describe-block hierarchy in output structure rather than flattening results, allowing LLMs to reason about test scope, shared setup, and feature-level organization without post-processing
vs alternatives: Standard test reporters either flatten results (losing hierarchy) or format hierarchy for human reading (verbose); this reporter exposes hierarchy as queryable JSON structure optimized for LLM traversal and scope-aware analysis

Parses and normalizes test failure stack traces into a structured format that removes framework noise, extracts file paths and line numbers, and presents error messages in a form LLMs can reliably parse. The reporter processes raw error objects from Vitest, strips internal framework frames, identifies the first user-code frame, and formats the stack in a consistent structure with separated message, file, line, and code context fields.
Unique: Specifically targets Vitest's error format and strips framework-internal frames to expose user-code errors, rather than generic stack trace parsing that would preserve irrelevant framework context
vs alternatives: Unlike raw Vitest error output (verbose, framework-heavy) or generic JSON reporters (unstructured errors), this reporter extracts and normalizes error data into a format LLMs can reliably parse for automated diagnosis
Captures and aggregates test execution timing data (per-test duration, suite duration, total runtime) and formats it for LLM analysis of performance patterns. The reporter hooks into Vitest's timing events, calculates duration deltas, and includes timing data in the output structure, enabling LLMs to identify slow tests, performance regressions, or timing-related flakiness.
Unique: Integrates timing data directly into LLM-optimized output structure rather than as a separate metrics report, enabling LLMs to correlate test failures with performance characteristics in a single analysis pass
vs alternatives: Standard reporters show timing for human review; this reporter structures timing data for LLM consumption, enabling automated performance analysis and optimization suggestions
Provides configuration options to customize the reporter's output format (JSON, text, custom), verbosity level (minimal, standard, verbose), and field inclusion, allowing users to optimize output for specific LLM contexts or token budgets. The reporter uses a configuration object to control which fields are included, how deeply nested structures are serialized, and whether to include optional metadata like file paths or error context.
Unique: Exposes granular configuration for LLM-specific output optimization (token count, format, verbosity) rather than fixed output format, enabling users to tune reporter behavior for different LLM contexts
vs alternatives: Unlike fixed-format reporters, this reporter allows customization of output structure and verbosity, enabling optimization for specific LLM models or token budgets without forking the reporter
Categorizes test results into discrete status classes (passed, failed, skipped, todo) and enables filtering or highlighting of specific status categories in output. The reporter maps Vitest's test state to standardized status values and optionally filters output to include only relevant statuses, reducing noise for LLM analysis of specific failure types.
Unique: Provides status-based filtering at the reporter level rather than requiring post-processing, enabling LLMs to receive pre-filtered results focused on specific failure types
vs alternatives: Standard reporters show all test results; this reporter enables filtering by status to reduce noise and focus LLM analysis on relevant failures without post-processing
Extracts and normalizes file paths and source locations for each test, enabling LLMs to reference exact test file locations and line numbers. The reporter captures file paths from Vitest's test metadata, normalizes paths (absolute to relative), and includes line number information for each test, allowing LLMs to generate file-specific fix suggestions or navigate to test definitions.
Unique: Normalizes and exposes file paths and line numbers in a structured format optimized for LLM reference and code generation, rather than as human-readable file references
vs alternatives: Unlike reporters that include file paths as text, this reporter structures location data for LLM consumption, enabling precise code generation and automated remediation
Parses and extracts assertion messages from failed tests, normalizing them into a structured format that LLMs can reliably interpret. The reporter processes assertion error messages, separates expected vs actual values, and formats them consistently to enable LLMs to understand assertion failures without parsing verbose assertion library output.
Unique: Specifically parses Vitest assertion messages to extract expected/actual values and normalize them for LLM consumption, rather than passing raw assertion output
vs alternatives: Unlike raw error messages (verbose, library-specific) or generic error parsing (loses assertion semantics), this reporter extracts assertion-specific data for LLM-driven fix generation
