Worked on the FoundationAgents/OpenManus repository to deliver a critical bug fix for MCPAgent’s multi-session tool management. Addressed issues with incorrect session access and tool listing by enabling aggregation of tools across all MCP sessions, thereby improving the robustness and reliability of tool orchestration in multi-session environments. Utilized Python for backend development and API integration, focusing on disciplined debugging and clear release hygiene. This work reduced cross-session interference and enabled safer automation workflows for multi-user scenarios. The approach emphasized careful coordination in session management, directly contributing to more reliable automation and enhanced business value through improved backend stability and bug fixing.
