AI agents use update to create or modify resources in Better Mcp Notion. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call update repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Better Mcp Notion.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Quickly update page properties without rewriting content. Much simpler than the write tool for property-only changes. The page content (blocks) is never touched — only properties are updated. Parameters - page: Page ID, URL, or name - properties: Key-value object of properties to set Examples Update a single property: update({ page: "abc123", properties: { "Status": "Done" } }) Update multiple properties: update({ page: "My Task", properties: { "Status": "Done", "Priority": "High", "Due Date": "2026-03-01" } }) Supported value types: - Text: "value" - Number: 42 - Checkbox: true / false - Date: "2026-03-01" - Date range: "2026-03-01 to 2026-03-15" - Select/Status: "Option Name" - Multi-select: ["tag1", "tag2"] - URL: "https://...". It is categorised as a Write tool in the Better Mcp Notion MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Better Mcp Notion MCP server in PolicyLayer and add a rule for update: 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.
update is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update 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 update. 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.
update 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.
