AI agents should default to read-only spreadsheet access for safety

The author advocates for granting AI agents read-only access to spreadsheets, arguing that the default read-write access poses significant risks. This approach prevents accidental data corruption and protects against prompt injection attacks that could manipulate data. By exposing only read-specific tools through protocols like MCP, the safety is structural rather than relying on the agent's adherence to rules.
