The workflow was using 'mcp_config_file' which is not a valid parameter for the claude-code-base-action. The correct parameter name is 'mcp_config' as defined in the action.yml file. This fix ensures that the MCP server configuration is properly passed to the action, allowing the GitHub MCP server to be correctly initialized. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: Claude <noreply@anthropic.com>
