ERCOT MCP server

Electric Reliability Council of Texas

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.

Example prompts

Questions a connected client can answer with the ERCOT resource.

  1. 01“Compare ERCOT real-time hub prices over the last 24 hours.”
  2. 02“Which ERCOT load forecast vintage best matched yesterday's actual demand?”
  3. 03“Find battery storage plants near the West load zone.”
  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
ERCOT-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 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 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.
