Use this from an AI assistant

An assistant that can read this data can answer questions no chatbot answers well today: whether two funds duplicate each other, what a portfolio really holds once you look through the funds, which companies sit in both of two positions.

Install the MCP server

npx -y tickerinside-mcp

In Claude Desktop, add it to the MCP servers section of your configuration with the command npx and the argument -y tickerinside-mcp. Cursor and other MCP clients take the same command.

Or paste this prompt

For an assistant with web access and no MCP support, this works as is:

Use the free TickerInside API at https://tickerinside.com/api/v1 to answer
questions about US fund holdings. Fetch /index.json to see what exists, then
/compare/{a}-vs-{b}.json for a pair or /fund/{ticker}.json for one fund.
Always report the holdings_as_of date with any overlap figure, and state which
of the three overlap measures you are quoting.

For crawlers and retrieval

A plain text map of the site is served at /llms.txt, and every page carries Dataset and Organization structured data with its licence and update date.

What the tools return

The MCP server exposes the same data as the JSON API: a comparison between two funds, a single fund with its holdings, and an overlap computation for an arbitrary list of funds. Every response carries the date of the underlying issuer file, so an assistant can say how fresh its answer is instead of implying it is live.
