Asi tree-sitter

AST-based code analysis using tree-sitter. Use for parsing code structure, extracting symbols, finding patterns with tree-sitter queries, analyzing complexity, and understanding code architecture. Supports Python, JavaScript, TypeScript, Go, Rust, C, C++, Swift, Java, Kotlin, Julia, and more.

Tree-sitter Code Analysis

Intelligent code analysis via AST parsing with tree-sitter.

When to Use

Understanding code structure across multiple languages
Extracting function/class definitions
Finding code patterns with tree-sitter queries
Analyzing code complexity
Symbol extraction and dependency analysis

Setup

MCP server configured in

~/.mcp.json

{
  "tree-sitter": {
    "command": "python3",
    "args": ["-m", "mcp_server_tree_sitter.server"],
    "cwd": "/Users/alice/mcp-server-tree-sitter"
  }
}

Usage Pattern

1. Register a Project First

register_project_tool(path="/path/to/project", name="my-project")

2. Explore Files

list_files(project="my-project", pattern="**/*.py")
get_file(project="my-project", path="src/main.py")

3. Analyze Structure

get_ast(project="my-project", path="src/main.py", max_depth=3)
get_symbols(project="my-project", path="src/main.py")

4. Search with Queries

find_text(project="my-project", pattern="function", file_pattern="**/*.py")
run_query(
  project="my-project",
  query='(function_definition name: (identifier) @function.name)',
  language="python"
)

5. Complexity Analysis

analyze_complexity(project="my-project", path="src/main.py")
