Splice Weaver
Provides AST-powered semantic code editing capabilities across 20+ programming languages through ast-grep integration, enabling precise structure-aware code modifications, scope-based navigation, and automated refactoring workflows with pattern matching and rule generation.
About
This MCP server provides AI assistants with AST-powered semantic code editing capabilities across 20+ programming languages through ast-grep integration, featuring automatic binary management and a dual-approach architecture optimized for both large and small language models. Built using Rust with comprehensive testing infrastructure, the implementation offers minimal core tools (find_scope for navigation and execute_rule for transformations) while providing extensive pattern libraries, guided workflows through MCP prompts, and rich documentation resources to make precise structure-aware code modifications accessible to models of all sizes. Serves developers needing surgical code refactoring capabilities, teams building AI-powered code analysis tools, and researchers studying LLM-tool interactions with support for scope-based editing, multi-language AST pattern matching, and automated rule generation workflows.
