What can the NYISO MCP server access?

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

Is this NYISO MCP server operated by New York Independent System Operator?

No. Ask the Grid runs it independently. Every catalog record names the original publisher and links to the source, including NYISO Market Information System (MIS).

How is MCP different from using NYISO Market Information System (MIS) 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 NYISO.
