Maguyva supports Go with AST parsing and symbol extraction, helping AI agents reason about package boundaries, service layers, composite literals, and dependency paths in backend code.

## Support snapshot

- Tier: AST and symbol support
- Programming
- Extensions: .go
- Real AST parsing for syntax-aware search and structural context.
- Named symbols feed semantic lookup and cross-reference. Graph navigation is available when relationship extraction is enabled.
- This language contributes symbols and relationships to graph-aware search; supported edge types vary with its native constructs.
- AST parsing and symbol extraction are both available.

## Best fit

- Backend and platform teams running Go services, CLIs, workers, and operational tooling in one repository.
- Repos where package boundaries are clean but the call chain still stretches across many small files.
- Teams using AI agents to inspect service behavior before touching handlers, repositories, or shared clients.

## Agent workflows

- Trace a request flow from handler to service to data-access layer before making a change.
- Find where a struct, package, or client is constructed and reused across the codebase.
- Compare neighboring implementations to preserve established service patterns.

## Why Go repositories benefit from structure-aware search

Go repositories often look easier than they are. The syntax is direct and the package model is usually tidy, so people assume search will be enough. Then the codebase grows into handlers, services, repositories, workers, and internal libraries, and suddenly a small change depends on understanding three packages and one shared type before touching anything.

That is the line between helpful AI assistance and blind editing. In Go, the hard part is rarely syntax. It is preserving package-level intent.

## What Maguyva actually extracts in Go

Maguyva keeps Go close to the language itself. The config intentionally avoids extra normalizers, which is a good fit for Go's comparatively direct syntax. Composite literals are treated as instantiations, and a large stdlib filter removes `fmt`, `context`, `time`, `json`, and similar calls from the relationship graph so repository code is easier to see.

That makes the graph more useful for real Go questions: where a struct gets constructed, which package owns an interface boundary, and how a request moves from handler to service to data layer.

## Useful MCP workflows for Go services

The MCP workflow is usually straightforward:

- `find_symbol` when you know the handler, service, interface, or client you want to inspect.
- `analyze_dependencies` when you want to understand outward coupling before changing a package or service.
- `dependency_search` with incoming traversal when you need impact radius for a shared type or client.

## Where this page is most relevant

This page is strongest for backend and platform code where Go is the main service language but not the whole repo. If infrastructure modules sit beside it, read [Terraform](/languages/terraform) too. If your evaluation is more about safety-critical systems programming, [Rust](/languages/rust) is the better comparison.

## Engine details

- Go intentionally skips extra normalizers because the syntax is already direct enough for tree-sitter to work cleanly.
- Composite literals count as instantiations, so the graph can follow where concrete structs are created instead of only where names are declared.
- A large stdlib filter keeps `fmt`, `context`, `time`, `json`, and similar calls from drowning out repository-specific relationships.

## Useful MCP entry points

- `find_symbol`: Use it when you know the handler, service, or interface name and want callers and references first.
- `analyze_dependencies`: Use it on a package or service symbol to understand outward coupling before a refactor.
- `dependency_search`: Use incoming traversal on a client or core type when you need to estimate blast radius.
