index

# Index Maintenance ## Check health ```bash code-graph-mcp health-check ``` ## Rebuild (incremental — only changed files) ```bash code-graph-mcp incremental-index ``` ## Full rebuild (when incremental isn't enough) ```bash code-graph-mcp rebuild-index --confirm ``` This builds the new index in a temporary location and swaps it in with an atomic rename, so a running MCP server (and its open WAL) never observes a half-built index. Deleting the `.code-graph/` directory by hand skips that swap, which is the exact situation the atomic path exists for. `get_index_status` and `rebuild_index` do dispatch over JSON-RPC, but they are deliberately kept out of `tools/list` to save tokens (`src/mcp/tools.rs`), so they are not in your callable tool set — the CLI above is the surface you have. It is also the only one that works with no server running.
