Auth is OAuth 2.1 with scopes mcp-tools and offline_access. Nothing evidences payment, sending or admin actions. Two presentation fixes: the read card is Low although it covers household invoices and 15-minute smart-meter series (personal data, so Medium), and the grid-operator data-release request has no card.","review_key":"claudesec:5faaf574-7634-495f-a1de-7f40b886b252","reviewed_at":"2026-10-12","runtime_verified":false,"sources":["https://www.gridbert.at/api-doku","https://www.gridbert.at/verbinden","https://smithery.ai/servers/ben-qo9f/gridbert","https://api.anthropic.com/api/directory/servers"],"status":"resolved"},"category":"Web Connector","confidence":"low","description":"Gridbert analyzes household electricity costs in the Austrian energy market.
