Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

vercel
check_vercel_python_project
Scan pasted project files for known Vercel Python-runtime deploy footguns: conflicting requirements.txt/pyproject.toml manifests, a dependency manifest missing from the project root, sibling-module imports that need sys.path, multiple top-level ASGI apps under api/, streaming/SSE responses that can crash the Python runtime, oversized dependencies (torch/tensorflow/etc.), and unrouted .well-known/ files. Static analysis over file contents -- it doesn't run a real build, so a clean result means 'no known footgun found,' not a deploy guarantee. To scan a public GitHub repo automatically instead of pasting files, use the $29 checkout at https://www.edgethirteen.com/tools/vercelpycheck.

Vercelpycheck — questions

Answers built from our own checks of this server.

What can Vercelpycheck do?
It exposes 1 tools, read directly from the server on our last check. Among them: check_vercel_python_project. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Vercelpycheck working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 35 of 92 checks got a reply (38.0%), average response time 712 ms. The bar chart above shows every period we have measured.
How do I connect Vercelpycheck?
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.
Does Vercelpycheck need an API key?
No. Vercelpycheck completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Vercelpycheck?
It answers our handshake in 712 ms on average, which is faster than 16% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
