ColorfulBox Inc. (Headquarters: Higashiosaka, Osaka; CEO: Hiroshi Kumagai) officially released a remote MCP server for its HR evaluation SaaS, 'Scale Personnel Evaluation' (https://colorfulbox.co.jp/scale), on April 28, 2026. This initiative allows Claude and other MCP-compatible AI clients to directly access data within Scale, enabling the automation and advancement of evaluation tasks.
■ Background: Why HR Digital Transformation Has Stalled
For many companies, the digitalization of HR evaluations has stopped at just 'installing a tool.' Even after implementing cloud-based systems, operations often involve double-handling: drafting in Excel, manually entering into the system, and managers copying and pasting comments. Tools exist, but the human workload remains. The root cause lies in the lack of integration between HR systems and AI. Even with excellent forms, if AI cannot read the data, automation is impossible. Tasks like generating feedback, checking goal alignment, and analyzing evaluation trends still require the inefficient flow of 'humans copying information to ask AI.' To bridge this gap, we developed the MCP server. In a world where AI can directly access HR system data, the nature of an HR professional's job will fundamentally change.
■ About Scale MCP
Scale MCP is a framework connecting AI agents (MCP clients) with the Scale Personnel Evaluation cloud. Through Scale MCP, AI agents can access data and perform operations autonomously on behalf of the user. Instead of traditional UI operations, users can simply talk to their AI tools to efficiently manage daily tasks like progress tracking, user management, and result analysis. Supported clients include Claude Code (CLI) and Cursor, with Claude Desktop support coming soon.
■ Design Philosophy: Empowering Companies to Establish Operations Locally
Scale is designed with the philosophy of encouraging companies to build their own evaluation systems and conduct meetings independently, reducing reliance on external consultants. Scale features standard 'AI Coach' functions:
- Goal Correction: AI suggests rewrites for clearer goals.
- Evaluation Comment Recommendations: Suggests feedback based on scores.
- Evaluation Analysis: Provides insights on results by department/position.
- 1on1 Topic Proposals: Generates interview themes from data.
While these UI-based features improve quality, another level of automation was needed to eliminate the operational bottleneck. MCP allows the delegation of administrative tasks (reminders, report creation) to AI agents, letting HR staff focus on their core work: system design, interviewing, and talent development.
■ Built 100% with Claude Code: High Affinity with MCP
Scale Personnel Evaluation is a SaaS developed 100% using Claude Code, Anthropic's AI coding agent. Because the entire codebase was built by an AI agent, it is designed from the ground up for seamless AI integration. This allows Scale to provide a more sophisticated and deeply integrated MCP experience compared to other SaaS products.
