AI agents may call schema to permanently remove or destroy resources in Better Mcp Notion. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call schema in a loop, permanently destroying resources in Better Mcp Notion. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.
Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

View or modify database schema (columns/properties). Actions "list" (default) — View current schema schema({ database: "Task Board" }) Returns: property names, types, and select/multi_select options. "add" — Add a new property schema({ database: "Task Board", action: "add", property: "Priority", type: "select", options: ["Low", "Medium", "High"] }) "remove" — Remove a property schema({ database: "Task Board", action: "remove", property: "Old Column" }) "rename" — Rename a property schema({ database: "Task Board", action: "rename", property: "Due", name: "Due Date" }) Supported types for add title, rich_text, number, select, multi_select, date, checkbox, url, email, phone_number, status, people, files For select/multi_select, you can provide initial options.. It is categorised as a Destructive tool in the Better Mcp Notion MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Better Mcp Notion MCP server in PolicyLayer and add a rule for schema: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Better Mcp Notion. Nothing to install.
schema is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the schema rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for schema. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
schema is provided by the Better Mcp Notion MCP server (better-mcp-notion). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
