Daily Firewall Report - November 22, 2025

⚠️ Authentication Issue Prevents Analysis

This workflow encountered an authentication limitation that prevented firewall log collection and analysis. The workflow uses the Copilot CLI engine, which requires access to GitHub CLI (gh aw) commands through the agentic-workflows MCP server.

Problem Description

The agentic-workflows MCP server is configured to run gh aw mcp-server commands, which in turn requires GitHub CLI authentication. However, the necessary authentication tokens are not available in the agent's execution environment:

• GITHUB_TOKEN: Not available in agent environment variables
• GH_TOKEN: Not available in agent environment variables
• COPILOT_GITHUB_TOKEN: Not available in agent environment variables (only set for Copilot CLI itself)

The workflow file shows that tokens are configured at the job level:

env:
  GH_TOKEN: ${{ secrets.GH_AW_GITHUB_TOKEN || secrets.GITHUB_TOKEN }}
  GITHUB_MCP_SERVER_TOKEN: ${{ secrets.GH_AW_GITHUB_TOKEN || secrets.GITHUB_TOKEN }}

However, these environment variables are not being passed through to the Copilot CLI agent execution context.

Impact

Without access to the agentic-workflows MCP tools, this workflow cannot:

• Collect firewall-enabled workflow runs using the logs tool
• Analyze firewall logs using the audit tool
• Generate comprehensive firewall activity reports
• Track blocked domains and network security patterns

Attempted Workarounds

1. ✗ Direct gh auth login - Failed (requires interactive authentication)
2. ✗ Setting GH_TOKEN environment variable - Not available in agent context
3. ✗ Using cached firewall data - No firewall-specific cache exists yet
4. ✗ Manual GitHub API calls - Would require token access

Recommended Solutions

Option 1: Pass GITHUB_TOKEN to Agent Environment (Recommended)

Modify the Copilot CLI execution step to explicitly pass the token:

- name: Run Copilot Agent
  env:
    COPILOT_GITHUB_TOKEN: ${{ secrets.COPILOT_GITHUB_TOKEN }}
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}  # Add this line
    GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}      # Add this line

The agentic-workflows MCP server configuration already expects GITHUB_TOKEN in its environment:

"env": {
  "GITHUB_TOKEN": "${GITHUB_TOKEN}"
}

Option 2: Pre-download Firewall Logs

Add a pre-processing step before the agent execution:

- name: Pre-download Firewall Logs
  env:
    GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
  run: |
    gh aw logs --firewall --start-date -7d --count 100 -o /tmp/gh-aw/firewall-data/

Option 3: Use GitHub API Directly

Create a custom MCP server that uses the GitHub API directly with the available GITHUB_MCP_SERVER_TOKEN.

Technical Details

MCP Configuration (from /home/runner/.copilot/mcp-config.json):

"agentic_workflows": {
  "type": "local",
  "command": "gh",
  "args": ["aw", "mcp-server"],
  "tools": ["*"],
  "env": {
    "GITHUB_TOKEN": "${GITHUB_TOKEN}"
  }
}

The MCP server expects GITHUB_TOKEN to be passed through environment variable substitution, but the token is not present in the agent's environment.

Next Steps

1. Immediate: Update workflow configuration to pass GITHUB_TOKEN to the agent environment
2. Test: Verify agentic-workflows MCP tools work after token is available
3. Re-run: Execute this workflow again to generate the first firewall report
4. Monitor: Ensure daily scheduled runs complete successfully

Missing Tool Report

A missing tool report has been generated with the following details:

• Tool: GitHub CLI authentication in Copilot agent context
• Reason: Cannot access agentic-workflows MCP tools due to missing GITHUB_TOKEN
• Alternatives: Pass token to agent environment, pre-download logs, or use GitHub API directly
