What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs a command on install [пакет] package.json:1
postinstall: node scripts/postinstall.mjs
  const filePath = path.join(outDir, fileName);
Runs an external command src/ci-issue.ts:14, src/handshake.ts:87
    execFile(cmd, args, (error, stdout, stderr) => {
          <td class="risk-cell">Financial data retrieval (Indian markets)</td>
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.

CI pipeline leaks secrets outward .github/workflows/gitee-sync.yml:23
          git remote add gitee "https://williamweishuhn:${{ secrets.GITEE_API_TOKEN }}@gitee.com/williamweishuhn/mcp-observatory.git" || git remote set-url gitee "https://williamweishuhn:${{ secrets.GITEE_API_TOKEN }}@gitee.com/williamweishuhn/mcp-observatory.git"

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

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

MCP Observatory — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Observatory?
MCP Observatory 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 @kryptosai/mcp-observatory was installed 520 times last week.
How do I connect MCP Observatory?
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 @kryptosai/mcp-observatory straight from npm; nothing to host, nothing to sign up for.
How many people use MCP Observatory?
The npm package @kryptosai/mcp-observatory was installed 520 times in the last week. Week over week that is -21%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is MCP Observatory open source?
Yes — it is published under the MIT licence, written in HTML, 146 stars on GitHub and 5 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
