What can the CAISO MCP server access?

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

Does the CAISO 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 CAISO 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 CAISO MCP server operated by California 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 CAISO OASIS and Today’s Outlook.

How is MCP different from using CAISO OASIS and Today’s Outlook 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 CAISO. The boundary is enforced in the resource URL, the OAuth audience, the discovery response, and the SQL validator — not by asking the model nicely.
