Nothing serious here today

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

This one needs environment variables set before it will start: SEMANTIC_API_KEY (Your Semantic API key from https://semanticapi.dev). The author declared them in the registry entry; get the values from the project itself.

Semantic API — questions

Answers built from our own checks of this server.

Why is there no uptime for Semantic API?

Semantic API 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 pypi package semanticapi-mcp was installed 58 times last week.

How do I connect Semantic API?

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 semanticapi-mcp straight from pypi; nothing to host, nothing to sign up for.

How many people use Semantic API?

The pypi package semanticapi-mcp was installed 58 times in the last week. Week over week that is -37%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
