What can the MISO MCP server access?

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

Does the MISO 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 MISO 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.

MISO MCP server

Midcontinent Independent System Operator

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

Under the hood.

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