This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add sytecheck-mcp -- npx -y @ascentws/sytecheck-mcp

This one needs environment variables set before it will start: SYTECHECK_API_KEY (SyteCheck API key, created at Account -> API keys on sytecheck.app. Begins with sck_.), SYTECHECK_API_URL (API base URL. Only set this to point at a non-production SyteCheck instance.). The author declared them in the registry entry; get the values from the project itself.

SyteCheck — questions

Answers built from our own checks of this server.

Why is there no uptime for SyteCheck?
SyteCheck 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 @ascentws/sytecheck-mcp was installed 354 times last week.
How do I connect SyteCheck?
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 @ascentws/sytecheck-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use SyteCheck?
The npm package @ascentws/sytecheck-mcp was installed 354 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 SyteCheck open source?
Yes — it is published under the MIT licence, written in TypeScript 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.
