PROFILE

Justin Chang

Over a two-month period, this developer enhanced the docker/mcp-registry and docker/mcp-gateway repositories by delivering five features and resolving two bugs focused on automation, interoperability, and remote server support. They implemented auto-merge workflows with security checks, improved testing infrastructure, and enabled Docker Catalog interoperability using Go and Shell scripting. Their work included adding remote MCP server support for collaborative tools, integrating the crush client into the MCP Toolkit, and supporting OCI artifact-based catalog imports. By refining configuration management, API integration, and continuous integration practices, they improved catalog workflows, developer experience, and compliance with evolving standards across distributed environments.

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
