Developer access
Free, read-only access to Yohei Nakajima's explicitly public build archive. No account, API key, or rate-plan signup is required.
Static JSON API
Start with the manifest, then fetch one or more year files.
curl -s https://yohei.me/data/manifest.json
curl -s https://yohei.me/data/projects-2026.json
OpenAPI 3.1 description · Project manifest
CLI
The CLI is one dependency-free Python file.
curl -fsSL https://yohei.me/yohei -o ~/.local/bin/yohei
chmod +x ~/.local/bin/yohei
yohei latest 5
yohei search activegraph
yohei topic econ
yohei date 2026-07-21
yohei --json get activegraph
Optional installer for both the CLI and MCP server:
curl -fsSL https://yohei.me/skills.sh | sh
Review the installer source before piping it to a shell.
MCP
The free MCP server runs locally over stdio and reads the public archive over HTTPS. It exposes latest_builds, search_builds, and get_build.
curl -fsSL https://yohei.me/mcp/yohei_mcp.py -o ~/.local/bin/yohei-mcp
chmod +x ~/.local/bin/yohei-mcp
Example client configuration:
{
"mcpServers": {
"yohei": {
"command": "/Users/YOU/.local/bin/yohei-mcp",
"args": []
}
}
}
This is intentionally a local stdio server. GitHub Pages is a static host and cannot provide a persistent remote MCP transport.
Agent discovery
- agents.md — when-to-use guidance and data conventions
- llms.txt — concise site map for language models
- /.well-known/agent-skills — machine-readable capabilities
- /.well-known/mcp — MCP discovery and installation metadata
Privacy and scope
Only records explicitly marked public are exposed. The API and tools are read-only and do not access private Airtable records, email, calendars, investments, or personal data.
