Context MCP

What it does

Context MCP is a local-first server that replaces inefficient grep-style codebase searches with a structural graph analysis. It parses code into an AST, stores it in SQLite, and uses a combination of PageRank, BM25, and semantic similarity to find the most relevant code symbols.

Tools

• context: Hybrid ranked search for discovery based on lexical and semantic signals.
• search_code: High-performance regex search across the indexed codebase.
• explore: Symbol discovery with integrated dependency analysis.
• read_symbol: Bounded, token-efficient inspection of specific code symbols.
• impact: Blast radius analysis to determine the risk of changes to a symbol.
• trace_call_path: Traces the execution flow between two specific symbols.
• understand: Deep analysis of a symbol including callers, callees, and centrality.
• get_architecture_summary: Extracts community clusters and entry points of the project.
