Worked on the zed-industries/zed repository to enhance interoperability and reliability of MCP communications by addressing a schema validation issue in notification handling. Using Rust and backend development skills, implemented a targeted change to the Notification struct so that the params field is omitted during serialization when its value is null, ensuring compatibility with MCP server requirements. This adjustment aligns notification behavior with existing Request message handling, promoting consistency across communication paths. The solution was validated through end-to-end internal MCP server tests, confirming successful discovery of MCP-provided tools. Additional tests were added to safeguard against regressions and maintain robust API integration.
