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 retain the ISO-NE boundary.

Does the ISO-NE MCP server require an account?

Yes. Compatible clients use OAuth 2.1 with PKCE, and you approve the connection while signed in to Ask the Grid.

Can the ISO-NE MCP server change data?

Market and catalog tools cannot change source market data: they are read-only, rate-limited, table-allowlisted, row-bounded, and audited. Separate write scopes can manage only the signed-in user's Ask the Grid alerts or queue an idempotent, reviewed Enterprise asset-hydration request.

ISO-NE MCP server

ISO New England

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.

14 ISO-NE datasets, query-ready.

Each one keeps its source, schema, coverage, and query notes — the agent reads those before it queries.

Under the hood.

Every credential is audience-bound to ISO-NE. The boundary is enforced in the resource URL, the OAuth audience, the discovery response, and the SQL validator — not by asking the model nicely.
