What can the NYISO MCP server access?

Only datasets registered for NYISO. The resource URL, OAuth audience, discovery responses, and SQL validator all retain the NYISO boundary.

Does the NYISO 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 NYISO 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.

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

No. Ask the Grid operates this MCP server independently. Each catalog record identifies its originating publisher and links to the source publication, including data from NYISO Market Information System (MIS).

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

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

Under the hood.

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