Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 12 min ago.

This one needs environment variables set before it will start: ATLAS_API_KEY (Atlas API Key for deterministic high-throughput web scraping and compilation). The author declared them in the registry entry; get the values from the project itself.

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

Atlas Web Compiler & Scraper — questions

Answers built from our own checks of this server.

Why is there no tool list for Atlas Web Compiler & Scraper?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.
Is Atlas Web Compiler & Scraper working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 79 of 79 checks got a reply (100.0%), average response time 329 ms. The bar chart above shows every period we have measured.
How do I connect Atlas Web Compiler & Scraper?
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 is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.
How do you sign in to Atlas Web Compiler & Scraper?
No API key is involved. Atlas Web Compiler & Scraper answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.
How fast is Atlas Web Compiler & Scraper?
It answers our handshake in 329 ms on average, which is faster than 42% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Atlas Web Compiler & Scraper?
The npm package @atlascompiler/mcp was installed 461 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 Atlas Web Compiler & Scraper 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.
