Use install-awmg.sh script for MCP gateway binary downloads in release mode #9079

Copilot · 2026-01-06T06:56:03Z

The MCP gateway download step in release mode now uses the install-awmg.sh script from the main branch instead of manually implementing platform detection and gh CLI downloads.

Changes

Modified pkg/workflow/gateway.go:

Downloads install-awmg.sh from main branch via curl
Uses the CLI's embedded version from GetVersion() and IsRelease() helpers to determine which version to download
Checks if awmg is already installed at $HOME/.local/bin/awmg before downloading to avoid unnecessary downloads
If the CLI is a release build, passes the CLI version to the install script
If the CLI is not a release build, downloads the latest version
Sets AWMG_CMD to $HOME/.local/bin/awmg after installation

Key Implementation

The function checks for existing awmg installations before downloading:

# Check if awmg is already in PATH
if command -v awmg &> /dev/null; then
  echo 'awmg is already available in PATH'
  echo "AWMG_CMD=awmg" >> $GITHUB_ENV
# Check for local awmg build
elif [ -f "./awmg" ]; then
  echo 'Using existing local awmg build'
  echo "AWMG_CMD=./awmg" >> $GITHUB_ENV
# Check if awmg is already installed at $HOME/.local/bin/awmg
elif [ -f "$HOME/.local/bin/awmg" ]; then
  echo 'awmg is already installed at $HOME/.local/bin/awmg'
  echo "AWMG_CMD=$HOME/.local/bin/awmg" >> $GITHUB_ENV
else
  # Download and install awmg
  ...
fi

The version selection uses the CLI's embedded Go code:

// Use the release tag from the CLI version if this is a release build
version := GetVersion()
if IsRelease() && version != "" && version != "dev" {
    gatewayLog.Printf("Using CLI release version: %s", version)
    stepLines = append(stepLines,
        "            # Download awmg for CLI release version: "+version,
        fmt.Sprintf("            /tmp/install-awmg.sh %s", version),
    )
} else {
    gatewayLog.Print("CLI is not a release build, downloading latest awmg")
    stepLines = append(stepLines,
        "            # Download latest awmg release (CLI is not a release build)",
        "            /tmp/install-awmg.sh",
    )
}

Examples

When compiled with gh-aw v1.2.3 (release build):

# Download awmg for CLI release version: v1.2.3
/tmp/install-awmg.sh v1.2.3

When compiled with gh-aw dev build:

# Download latest awmg release (CLI is not a release build)
/tmp/install-awmg.sh

This approach ensures:

Version consistency between the CLI and MCP gateway binary
Workflows compiled with gh-aw v1.2.3 will consistently use awmg v1.2.3
The generated code is specialized based on the compile-time release mode
Dev builds always get the latest version
Avoids unnecessary downloads when awmg is already installed

This centralizes installation logic in the script rather than duplicating platform detection and download logic in the compiled workflow.

[!WARNING]

Original prompt

Update the "Download MCP gateway" step code in release mode to use the install-awmg.sh script from main to download the awmg cli executable. Pass the release tag if available in the cli.

Changeset

Type: patch
Description: Use install-awmg.sh from main to download the awmg MCP gateway binary in release mode; checks for existing installations before downloading and passes the CLI release version when available to ensure version consistency.

@copilot generateMCPGatewayDownloadStep should generate specialized shell script code based on the release mode. It should change the generated code base on the mode.

Co-authored-by: pelikhan <[email protected]>

The release tag should be detected at runtime in the shell script based on GITHUB_REF, not at compile time in Go using GetCurrentGitTag(). This ensures that the same compiled workflow can adapt to different release contexts when it actually runs. Co-authored-by: pelikhan <[email protected]>

@copilot generateMCPGatewayDownloadStep should generate specialized shell script code based on the release mode. It should change the generated code base on the mode.

Fixed in 3fab956. The function now generates shell script code that detects the release tag at runtime using $GITHUB_REF, rather than detecting it at compile time. The generated code is now consistent regardless of when/where the workflow is compiled, and adapts to the actual GitHub Actions context at runtime.

pelikhan · 2026-01-06T07:33:56Z

@copilot use the release tag stored in the cli GO code itself, not GITHUB_REF. Use the helper to determine if isRelease

The release tag is now determined from the CLI's embedded version (GetVersion() and IsRelease()) rather than detecting it from GITHUB_REF at runtime. This ensures that workflows compiled with gh-aw v1.2.3 will download awmg v1.2.3, maintaining version consistency between the CLI and MCP gateway binary. Co-authored-by: pelikhan <[email protected]>

@copilot use the release tag stored in the cli GO code itself, not GITHUB_REF. Use the helper to determine if isRelease

Fixed in 6a8a36a. The function now uses GetVersion() and IsRelease() helpers to determine the version from the CLI's embedded Go code. When compiled with a release build (e.g., v1.2.3), it generates code that passes that version to install-awmg.sh. For dev builds, it downloads the latest version.

@copilot check if awmg is already available before using the install script.

Added a check for $HOME/.local/bin/awmg before downloading the install-awmg.sh script. If awmg is already installed at that location, the workflow will skip the download and use the existing binary, saving time and bandwidth. Co-authored-by: pelikhan <[email protected]>
