What can the CAISO MCP server access?

Only datasets registered for CAISO. The server URL, the sign-in token, search results and every query are all limited to that market.

Is this CAISO MCP server operated by California Independent System Operator?

No. Ask the Grid runs it independently. Every catalog record names the original publisher and links to the source, including CAISO OASIS and Today’s Outlook.

How is MCP different from using CAISO OASIS and Today’s Outlook directly?

The source portal stays the publication of record. The MCP server is built for an AI client: it can search Ask the Grid's catalog, read each table's schema and run read-only queries, with access limited to CAISO.

CAISO MCP server

The CAISO server lets your AI client search and query Ask the Grid's California market data, read-only. A token issued for it works on CAISO and nowhere else.
