index-mcp

What it does

index-mcp provides a high-performance bridge between a codebase and an AI agent. It scans a local workspace and creates a searchable SQLite index, allowing agents to perform semantic lookups and analyze repository history without reading every file on every request.

Tools

• ingest_codebase: Scans the project root and indexes files into the SQLite database.
• semantic_search: Performs hybrid lexical and embedding-based similarity search for code chunks.
• context_bundle: Assembles a tailored payload of related snippets for downstream prompts.
• repository_timeline: Summarizes recent commits and git history to provide temporal context.
• index_status: Checks if the index is stale relative to the current filesystem state.
