Go Archer

go-archer is a tool to inspect and analyze dependencies between packages in a project. It produces a graph of dependencies between packages in the project and selected third-party packages, it highlights dependencies that lead towards concrete packages, it estimates distance of the packages from the main sequence.

To install the binary:

go install gitlab.com/shaydo/go-archer/cmd/go-archer@latest

The command tries to load configuration from ~/.go-archer.toml by default. Configuration file might include some concrete packages that you want to track dependencies on and some exclusions:

concrete_packages = [
    "database/sql",
    "net/http",
]

ignore_packages = [
    "net/http/pprof",
]

To create dependency graph in PDF format run:

go-archer | dot -Tpdf -o deps.pdf

MCP Server

You can run go-archer as an MCP server. Here's an example of configuration:

{
  "mcpServers": {
    "go-archer": {
      "command": "go-archer",
      "args": ["mcp-server"],
      "env": {
        "HOME": "/home/me"
        "GOPATH": "/home/me/go"
      }
    }
  }
}

Note, that HOME and GOPATH enviroment variables are required for go-archer to be able to find the config file and go module cache.
