sqry

sqry is a local semantic code search tool. It parses source code into AST-backed symbol and relationship graphs so you can ask code questions that text search cannot answer reliably.

Everything runs on your machine. Indexing and querying make no network calls, and sqry sends no telemetry.

Current Capabilities

• 37 language plugins, 28 with full relation support and 9 with symbol extraction plus imports. By build cost, 29 are on the default fast path, json is compiled but excluded by default as high-wall-clock, and 7 specialty plugins sit behind Cargo features. The sqry://meta/manifest MCP resource reports these counts for the binary you have installed.
• Structural queries over symbol kind, language, visibility, names, return types, references, and relations.
• Graph analysis for callers, callees, imports, exports, call paths, cycles, unused symbols, duplicates, impact, semantic diff, and focused subgraphs.
• Edge-backed returns:<TypeName> and resolution-aware resolved_via:<kind> predicates for supported graph paths. See Call resolution predicates.
• Cross-language FFI edges. The C, C++, C#, Elixir, Haskell, Kotlin, Lua, PHP, R, Ruby, and Rust plugins emit FfiCall edges from mechanisms such as extern "C", DllImport / P/Invoke, JNI, Ruby FFI attach_function, and R .Call / Rcpp. Query them with sqry graph cross-language or the cross_language_edges MCP tool.
• Structural shape matching with sqry shape-match, which finds functions with similar body structure independently of their identifiers.
• A declarative rule layer. sqry rules run executes shipped rule IDs and packs, or your own TOML rule packs, against the graph; the rules_run MCP tool exposes the same engine.
• Go context propagation analysis (sqry context-propagation) for call sites that drop context.Context.
• Rust macro-boundary analysis: sqry cache expand builds a macro expansion cache, --expand-cache materializes macro-generated symbols as searchable nodes, and --cfg marks #[cfg]-gated symbols active or inactive. Both index-path options are execution-free.
• Visualization and export as Mermaid, Graphviz DOT, or D2 (sqry visualize, sqry export).
• An interactive shell (sqry shell) and batch runner (sqry batch) that keep the session cache warm across many queries.
• Incremental indexing with sqry update and sqry watch.
• Workspace-aware indexing through .sqry-workspace registries and VS Code .code-workspace sqry.workspace blocks.
• Daemon-backed shared graph loading through sqryd for editor, MCP, and repeated-agent workflows.
• One-shot repository orientation with sqry overview (and the matching generate_overview MCP tool for agents): a single report of the load-bearing hubs, path/package subsystems, complexity hotspots, potential issues, and ready-to-run follow-up queries.
• MCP integration for AI assistants. Standalone sqry-mcp currently exposes 39 tools; daemon-hosted MCP exposes a 17-tool subset. Use tools/list, sqry-mcp --list-tools, or sqry://meta/manifest as the authoritative catalog.
• LSP and VS Code extension support for editor workflows.

When To Use sqry

Use sqry when you need structural answers:

sqry index .
sqry overview            # orient in an unfamiliar repo, then run the queries it suggests
sqry query "kind:function AND visibility:public AND lang:rust"
sqry query "returns:Result"
sqry graph direct-callers authenticate
sqry graph trace-path main handle_request
sqry visualize "callers:authenticate" --format mermaid

Use ripgrep for simple text search, ast-grep for syntax rewrite patterns, language linters for policy enforcement, and an IDE language server for full editor semantics. sqry stays focused on local semantic code search.

Install

Linux And macOS

curl -fsSL https://raw.githubusercontent.com/verivus-oss/sqry/main/scripts/install.sh | bash -s -- --component all

The shell installer downloads release assets, verifies SHA256 checksums by default, and installs:

• sqry
• sqry-mcp
• sqry-lsp
• sqryd

Supported release platforms are Linux x86_64/arm64 (glibc and musl builds), macOS x86_64/arm64, and Windows x86_64.

Useful options:

curl -fsSL https://raw.githubusercontent.com/verivus-oss/sqry/main/scripts/install.sh | \
  bash -s -- --component all --version vX.Y.Z --verify-signatures

--verify-signatures requires gh or Cosign. It verifies the current release-artifacts.attestation.json GitHub artifact attestation from release-distribute.yml; older releases can still fall back to legacy per-asset Cosign bundles. SHA256 verification remains the default integrity check.

Windows

Invoke-WebRequest https://raw.githubusercontent.com/verivus-oss/sqry/main/scripts/install.ps1 -OutFile install.ps1
Get-Content .\install.ps1
.\install.ps1 -Component all -VerifySignatures

The PowerShell installer downloads the Windows x86_64 release ZIP, verifies checksums by default, and installs sqry.exe, sqry-mcp.exe, sqry-lsp.exe, and sqryd.exe into the user install directory.

Use a pinned release when reproducibility matters:

.\install.ps1 -Component all -Version vX.Y.Z -VerifySignatures

Homebrew

Homebrew is the package-manager surface currently backed by the public release manifest.

brew tap verivus-oss/sqry
brew install sqry

The formula installs sqry, sqry-mcp, sqry-lsp, and sqryd for Linux x86_64/arm64 and macOS x86_64/arm64.

Scoop, Winget, AUR, Nix, and Snap are not advertised as public release assets until their release-control surfaces are complete and validated.

Build From Source

git clone https://github.com/verivus-oss/sqry.git
cd sqry
cargo install --path sqry-cli
cargo install --path sqry-mcp
cargo install --path sqry-lsp
cargo install --path sqry-daemon

Requirements:

• Rust 1.94+ with Edition 2024.
• The repository pins toolchain 1.94.1 in rust-toolchain.toml.
• A full workspace build compiles the bundled tree-sitter grammars and language plugins and can require substantial disk space.

First Index

# Build the default fast-path index.
sqry index .

# Check status without rebuilding.
sqry index --status --json .

# Force a rebuild after upgrading across graph-format or semantics changes.
sqry index --force .

Index artifacts live under .sqry/. Add .sqry/ and legacy .sqry-index artifacts to your project ignore rules unless you intentionally share them.

Index Validation

sqry search main . --validate fail --auto-rebuild
sqry index --status --metrics-format prometheus .

--validate takes off, warn (default), or fail. Under fail a stale index aborts with exit code 2 instead of returning results computed from it, which is what makes it usable as a CI gate. --auto-rebuild rebuilds once and retries, and is a no-op under --validate off. Thresholds are tunable: --threshold-orphaned-files defaults to 0.20, so validation trips when more than 20% of indexed files no longer exist on disk, and --threshold-dangling-refs defaults to 0.05.

Note the limit: these are global flags, but validation is evaluated on the snapshot-loading path taken by search. Passing them to sqry index when an index already exists does not trigger a validation pass.

--metrics-format prometheus emits OpenMetrics-compatible text for scraping index status.

Plugin Selection

sqry records the plugin set that built an index so later graph-loading commands reuse the same semantics.

sqry index .                         # default fast path
sqry index --include-high-cost .     # all compiled non-default plugins
sqry index --exclude-high-cost .     # force the fast path
sqry index --enable-plugin json .    # opt into one plugin
sqry index --disable-plugin json .   # opt out of one plugin

The registry has fast plugins, high-wall-clock plugins, and optional specialty plugins. json is high-wall-clock. Optional specialty plugins include apex, abap, servicenow-xanadu-js, servicenow-xml, terraform, puppet, and pulumi when compiled with the matching Cargo features or specialty-plugins.

See Indexing for artifact cleanup, plugin tiers, and high-cost behavior.

Query Examples

# Symbol and attribute predicates.
sqry query "kind:function AND name:parse_*"
sqry query "kind:struct AND lang:rust"
sqry query "kind:function AND returns:Result"

# Relation predicates.
sqry query "callers:authenticate"
sqry query "callees:handle_request"
sqry query "imports:serde"

# Planner-backed query.
sqry plan-query "kind:function callers:main"

# Resolution-aware call filtering where populated by graph metadata.
sqry plan-query "kind:function callers:my_read resolved_via:binding_plane"

returns:<TypeName> uses graph TypeOf{Return} edges.

Call Resolution Predicates

resolved_via:<kind> filters call edges by what kind of binding produced the edge. That is a different question from how confident the resolver is: a duck_typed edge is not a low-confidence direct edge, it is a record that the call was bound by Python duck typing rather than by a syntactic reference. Knowing the mechanism lets you separate calls the compiler could have checked from calls that only resolve at runtime.

The parser accepts eight values:
