"Using ast-grep to Modify Code Programmatically" matching MCP tools:
- Search code using abstract syntax tree (AST) patterns via ast-grep. Provide a pattern and target language to locate matching code constructs.-
- Search Code-Fundi repositories with semantic search, grep over docs, or grep over code. Returns matching files with similarity scores, paths, and optional documentation.MIT
- Parses codebases with AST to extract functions, classes, and files, enabling relationship-aware code review and impact analysis.MIT
- Search, replace, or count code patterns using syntax-aware AST matching across 20+ programming languages.MIT
- Perform structural PHP code search with AST queries to detect anti-patterns like ->setX(null) calls and method chains missing null guards.MIT

Cloudflare Workers MCP server: code-explainer
- Scan a repository for potential bugs using AST pattern matching across 10 languages. Detects issues like mutable default arguments, bare excepts, unreachable code, and empty catch blocks.MIT
- Find code by syntax tree shape, not text. Use patterns like 'console.log($A)' for structural matches, ignoring whitespace and variable names. Ideal for lint-style queries and automated refactors.MIT
- Debug code rules by inspecting syntax tree structures. Use to discover correct syntax kinds and analyze how patterns are interpreted in ast-grep.MIT
- Detect GDPR compliance issues in Python, JavaScript, and TypeScript by analyzing source code with AST parsing, identifying cross-border data transfers, PII mishandling, and logging violations.MIT
- Search source code with AST context to understand how matches fit within functions, classes, and code structures.MIT
- Search code using structural pattern matching to find specific syntax patterns across multiple programming languages for refactoring, security auditing, and code analysis.MIT
- Find code by structure, not text: match syntax-aware patterns with metavariables to locate every call site shaped like a given example, returning file, line, and matched text.AGPL 3.0
- Search code in a project folder using AST patterns to locate specific code structures across multiple programming languages.MIT
- Search codebases using advanced AST pattern matching with YAML rules to locate complex code structures like nested or related syntax elements.MIT
- Generates a structured analysis request for Claude Code to analyze the codebase, using Read, Grep, and Glob, with instructions to call save_task_analysis afterwards.MIT
- Generate or modify code in AICre8 projects using AI. Write files, install packages, and update projects based on prompts.MIT
- Build a dependency graph of your codebase by mapping import/require/export relationships between files using static analysis, running in the background with progress polling.AGPL 3.0
- Parse JavaScript or TypeScript code from files or strings into an AST structure for subsequent code analysis and transformation tasks.MIT
- Retrieve supported languages, analysis categories, detected patterns, and configuration options for AST-based code analysis to identify GDPR compliance issues.MIT
- Locate the exact file, line, and scope where a symbol is defined in code files using AST-level metadata from local RAG indexing.MIT
