From 3bf53e449d96b434398acf78630cb0ff6d8b22ee Mon Sep 17 00:00:00 2001 From: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> Date: Wed, 27 Aug 2025 01:24:04 +0000 Subject: [PATCH 1/7] feat: split config parameter into config and config_file for better MCP client interoperability - Expand resolve_config() to accept config as dict or JSON string - Add separate config_file parameter for file paths - Update all MCP tools to use new parameter structure - Maintain backward compatibility with existing usage -
