# VistaShares *MCP Server*

Official, dated data on VistaShares ETFs and the site calculators, for Claude and other AI assistants.

VistaShares publishes an MCP (Model Context Protocol) server so AI assistants such as Claude can read official, dated facts about the 13 VistaShares ETFs and run the same calculators offered on this site. It is read-only, free and needs no account or key.

## Server address

https://www.vistashares.com/mcp (Streamable HTTP, JSON-RPC 2.0). Registry name: com.vistashares/etfs in the [official MCP Registry](https://registry.modelcontextprotocol.io/).

## How to connect

**Claude:** open Settings, then Connectors, and add VistaShares from the directory, or choose Add custom connector and paste the server address above. No sign-in is needed.

**Other MCP clients:** add a remote server with the address above. No authentication is required.

## Data handling

The server answers from the same published information as this website. It does not store the questions sent to it, the tool inputs or any conversation content. To prevent abuse it keeps a short-lived request counter keyed to a one-way hash of the caller’s network address, which expires after one minute. Like every page on this site, requests appear in standard web server logs. See our [privacy policy](https://www.vistashares.com/vistashares-privacy-policy/) and [data use terms](https://www.vistashares.com/data-use/).

## Support

*For information only; not investment advice or an offer to buy or sell shares. Investors should consider each fund’s investment objectives, risks, charges and expenses carefully before investing. The prospectus contains this and other information and should be read carefully before investing; it is available on each fund page. Investments involve risk, including possible loss of principal. ETF shares are bought and sold at market price, not net asset value.*
