"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
- Apply structured operations to a PART 12 Carve AST, validate them, and get the patched AST with canonical Carve source.MIT
- Replace text only within a named code symbol's body using AST scoping; changes stay confined to that symbol, leaving other code untouched.MITDestructive
- Parses codebases with AST to extract functions, classes, and files, enabling relationship-aware code review and impact analysis.MIT

Matching MCP Connectors
Parallel regex across all Boolsai scans — discover new vendor patterns, niche signals. 4 tools.
Math MCP server for primality, factorization, Java templates, and integer multiplication.
- Find functions, classes, and routes by name, architectural layer, or module, returning matching symbols with type, file, and layer. Use it instead of text grep to locate code by purpose.MIT
- Read a specific symbol's source code by name from a file. Uses AST parsing to find the exact definition, with optional context lines for focused inspection.MIT
- Find all references to a symbol across files using AST analysis, distinguishing definitions from usages.MIT
- Rename identifiers across code files in Patchloom using AST-aware edits that skip strings and comments, keeping references consistent.MITDestructive
- Analyzes Python source code via AST deconstruction to detect unsafe constructs, shell injection, dynamic eval, and socket egress before autonomous tool calls execute.Apache 2.0
- Perform structural PHP code search with AST queries to detect anti-patterns like ->setX(null) calls and method chains missing null guards.MIT
- Detect resource leaks, security vulnerabilities, and logic flaws in Python code via static AST analysis. Use before committing or running to catch defects without executing code.MIT
- 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
- Detect and repair hallucinated imports, identifiers, and method calls in AI-generated Python code by comparing candidate code against workspace AST symbol tables and applying AST corrections.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
- Match code by structural shape across 19 languages using AST metavariables, not text. Enables cross-language structural queries that grep cannot handle.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
