feat: pass GITHUB_HOST to GitHub MCP server for enterprise support by Copilot · Pull Request #20944 · github/gh-aw

Copilot · 2026-03-14T14:47:57Z

Summary

Ensures GITHUB_HOST (derived from GITHUB_SERVER_URL) is properly passed to the github/github-mcp-server in all rendering paths so that enterprise GitHub (GHE) deployments work correctly.

Changes

Local Docker mode (`RenderGitHubMCPDockerConfig`)

Added GITHUB_HOST to the container env section:

Copilot engine: "GITHUB_HOST": "\${GITHUB_SERVER_URL}" (Copilot CLI passthrough syntax)
Claude/Custom engines: "GITHUB_HOST": "$GITHUB_SERVER_URL" (plain shell variable)

The GITHUB_SERVER_URL is already present in the MCP gateway container environment (via -e GITHUB_SERVER_URL in mcp_setup_generator.go), so the gateway expands it when launching the child Docker container.

Remote mode (`RenderGitHubMCPRemoteConfig`)

Added GITHUB_HOST to the env section (Copilot engine) with value "\${GITHUB_SERVER_URL}" so the Copilot CLI can pass the correct GitHub host to the remote MCP server.

TOML mode (`renderGitHubTOML` — Codex engine)

Added GITHUB_HOST = "$GITHUB_SERVER_URL" to the env vars for the local Docker section.

Tests

Updated TestRenderGitHubMCPDockerConfig and TestRenderGitHubMCPRemoteConfig to assert GITHUB_HOST is present in the rendered output.

This PR correctly adds GITHUB_HOST to all GitHub MCP server rendering paths, enabling enterprise GitHub (GHES) support. The changes are well-structured across Docker local, remote, and TOML (Codex) modes. Left 2 minor comments about documentation and env var ordering consistency.

📰 BREAKING: Report filed by Smoke Copilot

github-actions · 2026-03-14T14:57:05Z

pkg/workflow/mcp_renderer_github.go

 		envVars := make(map[string]string)
 		envVars["GITHUB_PERSONAL_ACCESS_TOKEN"] = "$GH_AW_GITHUB_TOKEN"
+		// GitHub host for enterprise deployments
+		envVars["GITHUB_HOST"] = "$GITHUB_SERVER_URL"


Good addition! Including GITHUB_HOST here ensures TOML-rendered GHES deployments work correctly. Consider documenting that $GITHUB_SERVER_URL is already injected into the MCP gateway environment so readers understand why this variable is available.

github-actions · 2026-03-14T14:57:05Z

pkg/workflow/mcp_renderer_github.go

 		yaml.WriteString("                \"env\": {\n")
-		yaml.WriteString("                  \"GITHUB_PERSONAL_ACCESS_TOKEN\": \"\\${GITHUB_MCP_SERVER_TOKEN}\"\n")
+		yaml.WriteString("                  \"GITHUB_PERSONAL_ACCESS_TOKEN\": \"\\${GITHUB_MCP_SERVER_TOKEN}\",\n")
+		yaml.WriteString("                  \"GITHUB_HOST\": \"\\${GITHUB_SERVER_URL}\"\n")


The GITHUB_HOST env var is correctly added here for the remote Copilot MCP config. One small nit: the ordering GITHUB_PERSONAL_ACCESS_TOKEN before GITHUB_HOST is different from the Docker config where GITHUB_HOST comes first. Consider making the ordering consistent across all rendering paths for easier diffs in the future.

@copilot ensure GITHUB_HOST and GITHUB_SERVER_URL have the same expected format (check if https:// is required etc...)

Confirmed compatible — both use the same https://hostname format:

GITHUB_SERVER_URL (GitHub Actions): always set as full URL, e.g. https://github.com or https://myorg.ghe.com (no trailing slash — set by the GitHub Actions runner)
GITHUB_HOST (github-mcp-server): expects full URL with https:// per upstream README — "prefix the hostname with the https:// URI scheme"

So GITHUB_HOST = $GITHUB_SERVER_URL is the correct direct assignment with no transformation needed. Added explicit comments in all three rendering paths (local Docker, remote, TOML) to make this clear (488cd19).

Pull request overview

Adds propagation of GITHUB_HOST (derived from GITHUB_SERVER_URL) into GitHub MCP server configurations so GitHub Enterprise (GHE) deployments work across Docker/local, remote, and Codex/TOML rendering paths.

Changes:

Add GITHUB_HOST env var to GitHub MCP Docker/local JSON rendering (Copilot + non-Copilot variants).
Add GITHUB_HOST env var to GitHub MCP remote JSON rendering (Copilot env section).
Add GITHUB_HOST env var to Codex/TOML rendering and regenerate workflow lockfiles accordingly; update unit tests for Docker/remote renderers.
