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")Available Tools
