What can the ISO-NE MCP server access?

Only datasets registered for ISO-NE. The resource URL, OAuth audience, discovery responses, and SQL validator all hold that boundary.

Is this ISO-NE MCP server operated by ISO New England?

No. Ask the Grid operates it independently. Each catalog record names its original publisher and links to the source publication, including ISO-NE Web Services.

How is MCP different from using ISO-NE Web Services directly?

The source portal remains the publication of record. The MCP server gives AI clients typed dataset discovery, schema descriptions, ISO-NE-scoped authorization, and bounded read-only queries over Ask the Grid's catalog.

The ISO-NE MCP server gives compatible AI clients an ISO-bound path into Ask the Grid's New England catalog. Discovery, schemas, SQL validation, OAuth audience, and grid-asset reads all retain the ISO-NE boundary.
