Add standalone awmg CLI for MCP server aggregation by Copilot · Pull Request #7050 · github/gh-aw

Copilot · 2025-12-20T13:37:05Z

Merged Main and Recompiled (Third Iteration)

Successfully merged latest changes from main branch and recompiled all workflows.

Changes Completed:

Merged main branch - Integrated latest changes:
- Fixed Haskell action SHA in runtime setup test
- Updated action pins for security improvements
- Minor documentation and CI enhancements
Resolved merge conflict - Fixed conflict in dev.lock.yml by keeping our version with MCP gateway integration
Formatted code - Ran make fmt to ensure consistent formatting
Recompiled workflows - All 120 workflows successfully recompiled:
- Total size: 46.3 MB
- Total jobs: 709
- Total steps: 8,094
- Total scripts: 3,416 (12.8 MB)
- Top workflows: poem-bot (684.7 KB), smoke-copilot-playwright (535.7 KB), org-wide-rollout (501.2 KB)

MCP Gateway Implementation Retained:

✅ Config file rewriting - Properly reads original config and preserves non-proxied servers
✅ HTTP MCP format - Includes type:http and tools:["*"] fields for Copilot compatibility
✅ Docker networking - Uses host.docker.internal instead of localhost for firewall traversal
✅ Selective rewriting - Only proxied servers (external) are rewritten to gateway URLs
✅ Server preservation - safeinputs/safeoutputs remain unchanged with original command/args
✅ Gateway section removal - Gateway configuration removed from rewritten config
✅ Multi-format support - Automatically detects Claude, Copilot, and Codex config formats
✅ Comprehensive logging - Detailed logs for config loading, filtering, and rewriting operations
✅ All 43 CLI tests passing - Complete test coverage including new rewrite scenarios

Implementation Summary:

The awmg gateway now correctly:

Filters internal workflow servers (safeinputs/safeoutputs) from proxying
Reads original config file to preserve all servers
Only rewrites external MCP servers to point to gateway HTTP URLs
Preserves internal servers with their original command-based configuration
Uses host.docker.internal for Docker container networking
Includes proper HTTP MCP format fields (type, tools)
Removes gateway section from rewritten configuration

All changes are fully synchronized with main branch and tested.

Original prompt

Add a mcp-gateway command that implements a mininam MCP proxy application.

integrates by default with the sandbox.mcp extension point

imports the Claude/copilot/codex mcp server json configuration file

starts each mcp servers and mounts a mcp client on each

mounts a HTTP MCP server that acts as a gateway to the MCP clients

supports most MCP gestures through the go-MCP sdk

extensive logging to file (MCP log file folder)

add step in agent job to download gh-aw cli if released cli version or install local build

enable in smoke-copilot

@copilot compile as separate cli (awmg), update makefile with new build target

- Move IMPLEMENTATION_SUMMARY.md to specs/mcp-gateway.md - Remove feature flag requirement from gateway.go - Enable mcp-gateway in smoke-copilot.md workflow - Add MCP gateway test requirement to smoke-copilot - Integrate gateway step generation in mcp_servers.go - Update tests to reflect feature flag removal Co-authored-by: pelikhan <4175913+pelikhan@users.noreply.github.com>

@copilot enable mcp-gateway with smoke copilot.
Remove feature flag.

Completed in commit 8ade5e1:

Enabled mcp-gateway in smoke-copilot.md with sandbox.mcp configuration
Removed feature flag requirement - now enabled by default when sandbox.mcp is configured
Added MCP gateway test requirement to smoke test
Gateway steps now automatically generated in compiled workflows

@copilot the gateway should run as a command. Either using locally built cli or downloaded cli from releases (in cli release mode)

- Create cmd/awmg/main.go - standalone MCP gateway binary - Update Makefile with build-awmg target and build-all updates - Add awmg to .gitignore for all platforms - Update clean target to remove awmg binaries - Update help target to mention new binary - Add docs/awmg.md - documentation for standalone binary - Update DEVGUIDE.md to include awmg build instructions The awmg binary is a standalone version of the mcp-gateway command that can be distributed and run independently of gh-aw.

@copilot compile as separate cli (awmg), update makefile with new build target

Completed in commit e8d76c0:

Created standalone awmg binary in cmd/awmg/main.go
Added build-awmg target to Makefile
Updated build-all to include awmg for all platforms (Linux, macOS, Windows)
Added documentation in docs/awmg.md
Updated DEVGUIDE.md with build instructions

The awmg binary can now be built independently with make build-awmg or alongside gh-aw with make all.

- Update generateMCPGatewayStartStep to use awmg CLI command - Support three modes: local build, gh-aw extension, or download from releases - Fallback to 'gh aw mcp-gateway' if awmg not available - Platform detection for downloading correct binary (Linux/macOS/Windows, amd64/arm64) - Background process with PID tracking and log file - Update generateMCPGatewayHealthCheckStep to show gateway.log instead of docker logs - Update gateway_test.go to test for CLI command instead of Docker This removes the Docker dependency and allows the gateway to run as a native command using the awmg binary or gh-aw extension.

@copilot the gateway should run as a command. Either using locally built cli or downloaded cli from releases (in cli release mode)

Completed in commit 739f1ab:

Gateway now runs as CLI command instead of Docker container
Supports 3 modes: local build (./awmg), gh-aw extension, or download from GitHub releases
Platform detection for Linux/macOS/Windows (amd64/arm64)
Fallback to gh aw mcp-gateway if awmg unavailable
No Docker dependency required

@copilot add integration test that uses mcp-inspect to inspect a MCP configuration using playwright . Check tool list.
