ERCOT MCP server
The ERCOT server lets your AI client search and query Ask the Grid's Texas market data, with the schema of each table in hand before it writes a query. The connection only reaches ERCOT, so an answer never quietly mixes in another market.

Questions
- What can the ERCOT MCP server access?
- Only datasets registered for ERCOT. The server URL, the sign-in token, search results and every query are all limited to that market.
- Is this ERCOT MCP server operated by Electric Reliability Council of Texas?
- No. Ask the Grid runs it independently. Every catalog record names the original publisher and links to the source, including ERCOT Market Information System and data products.
- How is MCP different from using ERCOT Market Information System and data products directly?
- The source portal stays the publication of record. The MCP server is built for an AI client: it can search Ask the Grid's catalog, read each table's schema and run read-only queries, with access limited to ERCOT.
