Crate symgraph 

symgraph: Semantic code intelligence MCP server

A Rust-based MCP server that builds a knowledge graph of codebases to enhance AI-assisted code exploration. Uses tree-sitter for parsing and SQLite for storage.

Features

• Multi-language support: Rust, TypeScript, JavaScript, Python, Go, Java, C, C++
• Symbol extraction: functions, classes, methods, interfaces, etc.
• Relationship tracking: calls, contains, imports, exports, etc.
• Impact analysis: trace the effect of changes through the codebase
• Task context: build focused context for AI exploration

MCP Tools

• symgraph_context - Build task-specific code context
• symgraph_search - Find symbols by name
• symgraph_callers - Find all callers of a symbol
• symgraph_callees - Find all callees of a symbol
• symgraph_impact - Analyze change impact
• symgraph_node - Get detailed symbol information
• symgraph_status - Get index statistics
