Documentation

sqry semantic code search — query reference, MCP integration, LSP setup, and more.

Index your first codebase and run your first query in 5 minutes.

Install sqry via pre-built binaries, package managers, or build from source.

Install via Your Agent

Copy-paste prompts to make Claude Code, Codex CLI, Gemini CLI, Cursor, or Windsurf install sqry and wire itself up as an MCP client.

Configure sqry with .sqry/graph/config/config.json and environment variables.

Boolean query syntax — operators, fields, regex, and grouping.

Field Reference

Complete reference for every sqry query field.

Real-world sqry queries for common developer tasks.

MCP Integration

Connect Claude, Codex, and Gemini to sqry via the Model Context Protocol.

Keep code graphs warm in memory across CLI, LSP, and MCP sessions with the sqryd background process.

LSP Integration

Use sqry as a Language Server — standard LSP plus custom sqry methods for semantic queries.

Incremental Indexing

Hash-based change detection, cache-dir overrides, and Prometheus metrics export for fast re-indexing.

Language Support

sqry supports 37 language plugins — 28 with full relation support, 9 with symbol extraction plus imports.

Tune sqry cache, indexing speed, and query latency.

Macro Boundaries

Track Rust macro-generated symbols, filter by #[cfg] predicates, and inspect the macro-expansion cache.

Export sqry graphs as Mermaid, Graphviz DOT, and D2 diagrams.

Query across language boundaries — Rust↔C FFI, JS↔Python HTTP, SQL table access, and more.

Workspace Management

Index and query multiple repositories under a single workspace.

Interactive Shell

Explore your codebase in a REPL with warm index cache and query history.

Batch Processing

Run multiple queries from a file with parallel execution and structured output.

Run sqry analysis in CI — dead code, cycles, duplicates, and semantic diffs on every PR.

VSCode Extension

Semantic code search, analysis panels, and code lenses in Visual Studio Code.

Security & Supply Chain

Signed builds, SLSA provenance, SBOMs, dependency auditing, fuzzing, and mutation testing.

Diagnostics & Troubleshooting

Diagnostic bundles, usage insights, query history, and index repair.
