What the code does

We read the source, 8 h ago · rules ccca72095570

In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Builds a database query by concatenation .github/workflows/build.yml:60

      - name: Update asset version stamps
        run: |
          VERSION=$(date -u +%Y%m%d%H%M)

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

Nothing serious here today

Today is the operative word: we check Ajisai every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Ajisai — questions

Answers built from our own checks of this server.

Why is there no uptime for Ajisai?

Ajisai runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package ajisai-mcp-server was installed 274 times last week.

How do I connect Ajisai?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls ajisai-mcp-server straight from npm; nothing to host, nothing to sign up for.

How many people use Ajisai?

The npm package ajisai-mcp-server was installed 274 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Ajisai open source?

Yes — it is published under the MIT licence, written in Rust and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
