Third Hemisphere AI Authority Index missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Third Hemisphere AI Authority Index — questions

Answers built from our own checks of this server.

What can Third Hemisphere AI Authority Index do?
It exposes 12 tools, read directly from the server on our last check. Among them: get_blueprint_item_evidence, get_blueprint_progress, get_company_authority_score, get_company_score_history, get_edition_results, get_market_standing and 6 more. 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 →
What is Third Hemisphere AI Authority Index mostly used for?
Its tools cluster around blueprint and company. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Third Hemisphere AI Authority Index working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 721 ms. The bar chart above shows every period we have measured.
How do I connect Third Hemisphere AI Authority Index?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Third Hemisphere AI Authority Index need an API key?
No. Third Hemisphere AI Authority Index completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 12 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Third Hemisphere AI Authority Index?
It answers our handshake in 721 ms on average, which is faster than 11% 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.
