Prerequisites

• A Google Cloud account and project
• Billing enabled on the project
• The Cloud Firestore API enabled
• A Firestore Native mode database in Standard or Enterprise edition
• Google Cloud CLI for setup and authentication workflows
• IAM roles for the caller: MCP Tool User and Firestore User

• List collections under a document
• Create, get, list, update, and delete databases

• The docs recommend using a separate identity for agent access
• Model Armor and audit logging are recommended for security-sensitive deployments
