What can the PJM MCP server access?

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

Does the PJM 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 PJM 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 PJM MCP server operated by PJM Interconnection?

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 PJM Market Data.

How is MCP different from using PJM Market Data 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 PJM MCP server provides an ISO-bound interface to Ask the Grid's PJM catalog for compatible agents. Discovery, schemas, SQL validation, and OAuth tokens all retain the PJM boundary.

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