Capabilities10 decomposed

progressive-codebase-structure-mapping

Medium confidence

Maps project structure and extracts symbols (functions, classes, variables) through directory traversal combined with language-specific AST parsing via ast-grep and Python's native ast module. Returns a hierarchical tree view with optional symbol skeletons showing signatures, enabling AI assistants to understand codebase organization without loading entire files. Uses stateless architecture—no persistent index, analysis happens on-demand per request.

Solves for

I need to understand the overall structure of a codebase before diving into specific filesShow me all top-level functions and classes in this project so I can see what's availableGenerate a map of the codebase that an AI assistant can use to navigate intelligently

Best for

AI assistants (Claude, Cursor, VS Code) analyzing unfamiliar codebases

Teams onboarding new developers who need rapid codebase orientation

Developers building code-aware AI agents that need structural context

Requires

Python 3.10+

ast-grep-cli >=0.39.0 (binary dependency)

Git repository (for version tracking)

Limitations

Stateless design means no persistent caching across requests—each explore_repo call re-traverses the directory tree

Symbol extraction depth limited to top-level declarations; nested class methods require separate find_symbol queries

Large monorepos (10k+ files) may experience latency due to full directory traversal on each request

What makes it unique

Uses tree-sitter-based AST parsing via ast-grep for language-agnostic structural analysis instead of regex or text-based heuristics, combined with stateless on-demand analysis that avoids index maintenance overhead. Exposes symbol skeletons (signatures) directly in the tree view, giving AI assistants immediate context without requiring file reads.

vs alternatives

Faster than LSP-based solutions for initial codebase mapping because it doesn't require language server startup; more accurate than text-search-only tools because it understands syntax trees, not just keywords.

fuzzy-symbol-location-with-structural-ranking

Medium confidence

Locates specific functions, classes, or variables across a codebase by combining ast-grep structural search with fuzzy string matching (via thefuzz library). Ranks results by structural relevance (exact matches bubble up) and string similarity, returning symbol objects with precise file locations and line numbers. Handles symbol name variations and typos through fuzzy matching while maintaining structural accuracy via AST queries.

Solves for

Find where a specific function is defined so I can understand its implementationSearch for all classes matching a pattern (e.g., 'Handler' or 'Service') across the codebaseLocate a symbol even if I'm not sure of the exact name or spelling

Best for

AI assistants performing targeted code analysis on specific symbols

Developers refactoring code who need to find all usages of a symbol

Teams building code-aware search features for internal tools

Requires

Python 3.10+

ast-grep-cli >=0.39.0

thefuzz >=0.20.0 (fuzzy matching library)

Limitations

Fuzzy matching adds latency (~50-200ms per query depending on codebase size) due to string similarity computation

Structural search limited to declarations; cannot distinguish between overloaded methods in languages without explicit overload syntax

Ranking algorithm is heuristic-based; very similar symbol names may not rank in expected order

What makes it unique

Combines ast-grep's structural AST queries with thefuzz fuzzy matching to handle typos and partial names while maintaining structural accuracy. Ranking algorithm prioritizes structural matches (exact AST node type matches) over pure string similarity, ensuring that a search for 'User' returns the User class before UserHelper or user_factory functions.

vs alternatives

More resilient to typos and naming variations than pure AST-based tools (e.g., Language Server Protocol implementations), while more structurally accurate than text-search tools like ripgrep that cannot distinguish between symbol declarations and string literals.

impact-analysis-via-reference-tracking

Medium confidence

Analyzes where a symbol is referenced across the codebase by using ripgrep for fast text-based search (primary) with Python AST fallback for Python-specific analysis. Returns reference count and precise locations (file, line number) for each usage, enabling AI assistants to understand change impact before refactoring. Stateless design means queries execute on-demand without maintaining a dependency graph.

Solves for

Before I rename a function, show me everywhere it's called so I understand the impactFind all places where a specific class is instantiated or importedUnderstand how widely used a particular module or symbol is across the codebase

Best for

Developers performing refactoring who need to assess change scope

AI assistants generating code changes that must update all references

Teams analyzing technical debt by measuring symbol coupling

Requires

Python 3.10+

ripgrep binary (optional but recommended for performance)

Python ast module (built-in, for Python fallback)

Limitations

Text-based search (ripgrep) cannot distinguish between symbol usage and string literals containing the symbol name—false positives in comments, strings, and unrelated identifiers

Python AST fallback only available for Python code; JS/TS/Go rely on ripgrep text search which is less precise

No semantic understanding of imports/aliases—if a symbol is imported as a different name, references may be missed or require manual filtering

What makes it unique

Implements a two-tier search strategy: ripgrep for speed (can scan 100k+ lines in <100ms) with Python AST fallback for precision on Python code. Avoids building a persistent dependency graph (which would require index maintenance), instead computing references on-demand—trading latency for simplicity and zero index overhead.

vs alternatives

Faster than LSP-based reference finding because it doesn't require language server initialization; more practical than full semantic analysis tools because it works across multiple languages with a single stateless implementation, though less precise than semantic tools that understand import aliases and scoping rules.

mcp-protocol-server-integration

Medium confidence

Exposes the three core tools (explore_repo, find_symbol, what_breaks) as MCP (Model Context Protocol) server endpoints via the FastMCP framework. Handles request/response serialization, error handling, and protocol compliance, allowing any MCP-compatible AI assistant (Claude, Cursor, VS Code) to invoke code analysis tools as native functions. Server runs as a subprocess managed by the AI assistant's MCP client configuration.

Solves for

I want Claude or Cursor to be able to analyze my codebase without copy-pasting code snippetsIntegrate code intelligence into my AI assistant so it can make informed decisions about my projectSet up XRAY as a tool that my AI assistant can call automatically during conversations

Best for

Developers using Claude Desktop, Cursor Editor, or VS Code with MCP support

Teams building custom AI agents that need code analysis capabilities

Organizations integrating XRAY into existing MCP-based AI workflows

Requires

Python 3.10+

fastmcp >=0.1.0

MCP-compatible AI assistant (Claude Desktop, Cursor, VS Code with MCP extension)

Limitations

MCP protocol overhead adds ~50-100ms per request due to serialization and subprocess communication

Server is stateless—each request is independent, no session persistence or request batching

Requires MCP client configuration (JSON) to be manually set up; no auto-discovery of XRAY server

What makes it unique

Uses FastMCP framework to expose Python functions as MCP tools with minimal boilerplate—tool definitions are auto-generated from function signatures and docstrings. Server runs as a subprocess managed by the MCP client, avoiding the need for manual HTTP server setup or port management.

vs alternatives

Simpler to integrate than REST API servers because MCP clients handle subprocess lifecycle and communication; more standardized than custom tool protocols because it follows the MCP specification, enabling compatibility with multiple AI assistants (Claude, Cursor, VS Code) without adapter code.

multi-language-ast-parsing-via-tree-sitter

Medium confidence

Provides language-agnostic code analysis by leveraging tree-sitter-based AST parsing through the ast-grep binary. Supports Python, JavaScript/TypeScript, and Go with a single unified interface—no language-specific parsers or grammar files required. ast-grep handles language detection via file extension and provides structural queries that work across all supported languages, enabling consistent symbol extraction and search behavior.

Solves for

Analyze a polyglot codebase (Python + JS + Go) with a single tool without language-specific configurationExtract function and class definitions from any supported language using the same APIBuild code intelligence features that work across multiple languages without duplicating logic

Best for

Teams with polyglot codebases (microservices, full-stack applications)

Developers building language-agnostic code analysis tools

AI assistants that need to work across multiple programming languages

Requires

Python 3.10+

ast-grep-cli >=0.39.0 (binary, must be in PATH)

Supported file types: .py, .js, .ts, .jsx, .tsx, .go

Limitations

Language support limited to Python, JavaScript/TypeScript, and Go—no support for Java, C++, Rust, or other languages

ast-grep binary must be installed separately; no pure Python fallback for all languages

Language detection relies on file extension; ambiguous extensions (e.g., .js for both JavaScript and JSX) may require manual specification

What makes it unique

Delegates AST parsing to ast-grep (a Rust binary wrapping tree-sitter), avoiding the need to maintain language-specific parsers in Python. This design trades a binary dependency for simplicity and performance—tree-sitter parsing is significantly faster than pure Python AST modules and supports more languages.

vs alternatives

More performant and maintainable than language-specific parser libraries (e.g., ast for Python, @babel/parser for JS) because it uses a single unified tool; more flexible than LSP-based solutions because it doesn't require language servers to be installed for each language.

caching-strategy-with-git-aware-invalidation

Medium confidence

Implements a caching layer that stores analysis results (symbol maps, reference indices) with Git-aware invalidation. Cache entries are invalidated when file modification times change or when Git detects new commits, avoiding stale results while minimizing redundant analysis. Caching is transparent to the user—no manual cache management required. Stateless server design means cache is per-request, not global.

Solves for

Speed up repeated queries on the same codebase without re-analyzing unchanged filesEnsure that analysis results stay fresh when code is modified or pulled from GitReduce latency for AI assistants making multiple queries during a single conversation

Best for

Developers working on large codebases where repeated analysis would be slow

AI assistants making multiple sequential queries on the same codebase

Teams using XRAY in CI/CD pipelines where caching can reduce analysis time

Requires

Python 3.10+

Git repository (optional, for Git-aware invalidation)

File system with modification time tracking

Limitations

Cache invalidation is file-level, not symbol-level—modifying a single function invalidates the entire file's symbol cache

Git-aware invalidation requires a .git directory; non-Git repositories fall back to file modification time checks

Cache is stored in memory or on disk (implementation detail); no distributed cache support for multi-machine setups

What makes it unique

Combines file modification time tracking with Git commit detection for intelligent cache invalidation—avoids stale results when code changes while minimizing false cache misses. Cache is transparent to the MCP layer, implemented in the XRayIndexer core engine without requiring user configuration.

vs alternatives

More practical than no caching because it significantly reduces latency for repeated queries; more robust than simple TTL-based caching because it detects actual code changes via Git and file modification times, not just elapsed time.

stateless-architecture-with-on-demand-analysis

Medium confidence

Implements a stateless server design where each request is analyzed independently without maintaining persistent indices or dependency graphs. Analysis happens on-demand by invoking external tools (ast-grep, ripgrep) per request, avoiding the complexity of index maintenance and synchronization. This design trades per-request latency for operational simplicity—no background indexing, no index corruption, no cache coherency issues.

Solves for

I want a code analysis tool that works immediately without waiting for indexingAvoid the complexity of maintaining and updating a persistent code indexDeploy XRAY without worrying about index synchronization across multiple instances

Best for

Developers who want immediate code analysis without indexing overhead

Teams deploying XRAY in ephemeral environments (containers, serverless)

Projects where code changes frequently and index staleness is a concern

Requires

Python 3.10+

ast-grep-cli >=0.39.0

ripgrep (optional, for faster text search)

Limitations

Each request incurs full analysis cost—no amortization of parsing across multiple queries

Large codebases (100k+ files) may experience noticeable latency (1-5 seconds) per request due to full traversal

No persistent symbol graph—complex queries (e.g., 'find all functions that call this function') require multiple sequential requests

What makes it unique

Deliberately avoids persistent indexing to eliminate index maintenance complexity. Instead of building and maintaining a symbol graph, XRAY invokes external tools (ast-grep, ripgrep) per request. This design is inspired by serverless architectures where statelessness enables horizontal scaling and eliminates synchronization issues.

vs alternatives

Simpler to deploy and maintain than indexed solutions (e.g., Sourcegraph, Kythe) because there's no background indexing process or index corruption to debug; more suitable for ephemeral environments (containers, CI/CD) because there's no persistent state to manage. Trade-off: higher per-request latency for large codebases.

structural-vs-text-search-hybrid-approach

Medium confidence

Provides two complementary search strategies: structural search via ast-grep (understands code syntax and semantics) and text search via ripgrep (fast pattern matching). The tool layer chooses the appropriate strategy based on query type—structural search for symbol definitions and declarations, text search for references and usage patterns. Hybrid approach balances precision (structural) with speed (text) and cross-language support.

Solves for

Find where a symbol is defined (structural) vs where it's used (text-based)Search for code patterns that may not be valid syntax (e.g., comments or string literals)Understand the trade-offs between precision and speed for different query types

Best for

Developers who need both precise symbol location and fast reference finding

AI assistants performing multi-step code analysis (definition lookup + usage analysis)

Teams analyzing code patterns that span multiple languages

Requires

Python 3.10+

ast-grep-cli >=0.39.0 (for structural search)

ripgrep (optional, for text search)

Limitations

Structural search (ast-grep) is slower than text search (ripgrep) but more accurate—no automatic optimization to choose the fastest approach

Text search cannot distinguish between symbol usage and string literals—requires manual filtering or post-processing

Structural search only works for supported languages (Python, JS/TS, Go); text search is language-agnostic but less precise

What makes it unique

Explicitly separates structural search (ast-grep for syntax-aware queries) from text search (ripgrep for pattern matching), allowing each tool to be optimized for its use case. Tool selection is transparent to the user—the tool layer automatically chooses the appropriate strategy based on the query type.

vs alternatives

More flexible than pure structural tools (LSP, Kythe) because it can search for patterns that aren't valid syntax; more accurate than pure text search tools because it understands code structure. Hybrid approach enables both precision and speed without requiring the user to choose.

minimal-dependency-philosophy-with-binary-wrappers

Medium confidence

Implements XRAY with minimal Python dependencies (only fastmcp and thefuzz) by delegating heavy lifting to external binaries (ast-grep, ripgrep) via subprocess calls. Python code focuses on orchestration and result formatting, not parsing or searching. This design reduces Python package bloat, simplifies dependency management, and leverages battle-tested tools (ast-grep, ripgrep) instead of reimplementing them in Python.

Solves for

I want a lightweight Python package that doesn't pull in dozens of transitive dependenciesUse proven tools (ast-grep, ripgrep) instead of reinventing parsing and searching in PythonDeploy XRAY with minimal installation footprint and fast startup time

Best for

Developers who value minimal dependencies and fast installation

Teams deploying XRAY in constrained environments (embedded systems, CI/CD with bandwidth limits)

Projects that want to leverage existing tools (ast-grep, ripgrep) rather than Python alternatives

Requires

Python 3.10+

fastmcp >=0.1.0 (Python dependency)

thefuzz >=0.20.0 (Python dependency)

Limitations

Binary dependencies (ast-grep, ripgrep) must be installed separately and available in PATH—no automatic binary installation

Subprocess calls add overhead (~10-50ms per invocation) compared to in-process libraries

Binary compatibility issues may arise on unusual platforms (e.g., ARM, Alpine Linux)—ast-grep and ripgrep may not have pre-built binaries

What makes it unique

Deliberately minimizes Python dependencies by wrapping external binaries (ast-grep, ripgrep) instead of using Python equivalents. This design philosophy prioritizes simplicity and leveraging proven tools over self-contained Python packages. Orchestration logic in Python is thin—mostly subprocess invocation and result parsing.

vs alternatives

Lighter weight than all-in-Python solutions (e.g., using tree-sitter-python, ripgrep-py) because it avoids shipping language-specific parsers; faster to install because it has fewer transitive dependencies. Trade-off: requires binary dependencies to be pre-installed, which adds deployment complexity.

ai-assistant-integration-via-mcp-config

Medium confidence

Provides configuration templates and auto-generation tools for integrating XRAY into AI assistants (Claude Desktop, Cursor, VS Code) via MCP configuration files. Includes an MCP config generator that creates the necessary JSON configuration (claude_desktop_config.json, etc.) with correct paths and parameters. Simplifies the integration process from manual JSON editing to a single command.

Solves for

I want to add XRAY to my Claude Desktop setup without manually editing JSONGenerate the correct MCP configuration for my specific environment and Python installationIntegrate XRAY into Cursor or VS Code with minimal setup steps

Best for

Individual developers setting up XRAY for personal use

Teams deploying XRAY across multiple developer machines

Non-technical users who want to integrate XRAY without understanding MCP protocol details

Requires

Python 3.10+

XRAY installed via pip or uv

AI assistant installed (Claude Desktop, Cursor, or VS Code)

Limitations

Config generator assumes standard installation paths; custom Python installations or virtual environments may require manual path adjustment

Generated configuration is static—changes to XRAY installation path require regenerating the config

Different AI assistants (Claude Desktop, Cursor, VS Code) have different config file locations and formats—generator must support all variants

What makes it unique

Automates MCP configuration generation instead of requiring users to manually edit JSON files. Generator detects the Python installation path and XRAY location, then creates the correct configuration for the target AI assistant. Reduces setup friction from 5-10 manual steps to a single command.

vs alternatives

More user-friendly than manual JSON editing because it abstracts away MCP protocol details; more robust than hardcoded example configs because it adapts to the user's specific environment and installation paths.
