PROFILE

Justin Chang

Justin Chang contributed to the docker/mcp-registry and docker/mcp-gateway repositories by building features that enhanced automation, interoperability, and remote server support. He implemented an auto-merge workflow for pin upgrade pull requests with security checks and concurrency controls, and improved Docker Catalog interoperability by converting community registry servers to a compatible format. In the following month, Justin added remote MCP server support for collaborative tools and enabled catalog import as OCI artifacts, streamlining catalog management. His work leveraged Go, Bash, and Docker, with a focus on robust API development, configuration management, and continuous integration, demonstrating depth in backend and DevOps engineering.

February 2026 monthly summary focusing on delivering business value and technical achievements across docker/mcp-registry and docker/mcp-gateway. Key features delivered: - Remote MCP server support added for Granola and Miro (granola-remote, miro-remote), enabling access to meeting notes, conversations, diagrams, and documents in collaborative workspaces. Includes server configuration, MCP compliance, and basic docs. - OCI artifact-based catalogs: import of community registry catalogs as OCI artifacts, with support for catalog creation, push/pull, and opt-in publishing. Major bugs fixed: - Fixed a bug in BuildConfigSchema to omit the 'required' field when no config variables are required, preventing JSON null and load issues for community catalogs. Overall impact and accomplishments: - Expanded MCP ecosystem capabilities by enabling remote context for tasks, improved automation for ticket creation and summaries, and more reliable catalog workflows with community registry support. - Strengthened developer experience with integrated tooling (MCP Toolkit crush client) and catalog distribution via OCI artifacts, improving consistency across environments. Technologies/skills demonstrated: - MCP API compliance for remote servers and toolkit - Go JSON marshaling nuances and robust schema handling - Docker MCP Toolkit integration and crush client workflow - OCI artifacts, catalog publishing, and CI/testing practices
