Overview

AI-generated overview

Read-only access to Third Hemisphere's AI Authority Index: CRISP scores and AI visibility readings for companies across measured markets.

What you can do
  • Browse index editions and their markets, publication dates, DOIs and open-data links
  • Read an edition section's published results, including Star Chart cells, CRISP scores, factor readings and AI answer counts
  • Look up a company's CRISP score and AI visibility per market, or its full dated score history

When to use it
Useful when you need published, citable figures on how visible or authoritative companies are in AI answers, for market comparisons, brand or PR research, or tracking a company's scores over time.
Requirements
A remote streamable HTTP endpoint; no local runtime or package. No authentication is required. An optional free API key can be sent in the x-api-key header for higher rate limits.
Before you install
All tools are read-only, so nothing is written or changed. The API key is optional and only affects rate limits. Quoted scores should be reproduced exactly with their market, month and source attribution, and the data is licensed CC BY 4.0.

Installation

In SourceWeft

  1. Open Third Hemisphere AI Authority Index in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/agency.thirdhemisphere%2Fai-authority-index/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
