What can the ERCOT MCP server access?

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

Does the ERCOT 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 ERCOT 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 ERCOT MCP server operated by Electric Reliability Council of Texas?

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 ERCOT Market Information System and data products.

How is MCP different from using ERCOT Market Information System and data products 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.

The ERCOT MCP server gives compatible AI clients a bounded, schema-aware path into Ask the Grid's Texas market catalog. The connection is fixed to ERCOT, so a tool call cannot silently cross into another ISO.

41 ERCOT 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 ERCOT. The boundary is enforced in the resource URL, the OAuth audience, the discovery response, and the SQL validator — not by asking the model nicely.
