PJM MCP server

PJM Interconnection

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.

Example prompts

Questions a connected client can answer with the PJM resource.

  1. 01“Compare PJM prices across the western and eastern zones today.”
  2. 02“Show PJM load versus the most recent forecast for each hour.”

  4. 04“Get the published intelligence dossier for this plant, or request hydration if it is missing.”

Access and authorization

The client discovers Ask the Grid’s authorization server, sends you through sign-in, and asks you to approve the exact scopes it needs.

Authentication
OAuth 2.1 with PKCE S256
Default scopes
mcp:catalog.read · mcp:grid.read · mcp:sql.read · mcp:assets.read
Hydration scope
mcp:assets.write · Enterprise approval required
Safety boundary
PJM-only audience, table allowlist, row limits, and audited calls

Opening the resource from a compatible client while signed out routes through the standard Ask the Grid sign-in page before the authorization screen.

Frequently asked questions

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 are read-only, rate-limited, table-allowlisted, row-bounded, and audited. Enterprise users can separately approve a write scope that only queues an idempotent, reviewed asset-hydration request.
