Outputs and Achievements
Documenting concrete deliverables from MCP development and utilization.
About This Document
This document catalogs the concrete deliverables produced through MCP ecosystem development. It is organized into four categories: MCP servers, technical documentation, translation outputs, and technical articles, with each entry including an overview, repository URL, and quantitative metrics.
By visualizing "what was built" and "how much value was generated," this serves as a reference for future planning and as supporting material for external communications.
Deliverable Categories
The deliverables produced through MCP development are organized into the following four primary categories. Below is a mind map visualizing the relationships and composition of each category.

Publication Strategy
Note = Conceptual and opinion-based content
(MCP philosophy, knowledge democratization, AI-driven development theory)
Qiita = Technical tips and tool introductions
(though the SEO culture raises some concerns)
Zenn = Detailed technical articles and tutorials
(though it can feel one-directional)
GitHub = Implementation and source code
(the substance of deliverables)5. Other Achievements
