AI agents use notion-create-database to create or modify resources in 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 notion-create-database 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 Notion.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Creates a new Notion database using SQL DDL syntax. If no title property provided, "Name" is auto-added. Returns Markdown with schema, SQLite definition, and data source ID in <data-source> tag for use with update_data_source and query_data_sources tools. The schema param accepts a CREATE TABLE statement defining columns. Type syntax: - Simple: TITLE, RICH_TEXT, DATE, PEOPLE, CHECKBOX, URL, EMAIL, PHONE_NUMBER, STATUS, FILES - SELECT('opt':color, ...) / MULTI_SELECT('opt':color, ...) - NUMBER [FORMAT 'dollar'] / FORMULA('expression') - RELATION('data_source_id') — one-way relation - RELATION('data_source_id', DUAL) — two-way relation - RELATION('data_source_id', DUAL 'synced_name') — two-way with synced property name - RELATION('data_source_id', DUAL 'synced_name' 'synced_id') — two-way with synced name and ID (for self-relations) - ROLLUP('rel_prop', 'target_prop', 'function') - UNIQUE_ID [PREFIX 'X'] / CREATED_TIME / LAST_EDITED_TIME - Any column: COMMENT 'description text' Colors: default, gray, brown, orange, yellow, green, blue, purple, pink, red <example description="Minimal">{"schema": "CREATE TABLE ("Name" TITLE)"}</example> <example description="Task DB">{"title": "Tasks", "schema": "CREATE TABLE ("Task Name" TITLE, "Status" SELECT('To Do':red, 'Done':green), "Due Date" DATE)"}</example> <example description="With parent and options">{"parent": {"page_id": "f336d0bc-b841-465b-8045-024475c079dd"}, "title": "Projects", "schema": "CREATE TABLE ("Name" TITLE, "Budget" NUMBER FORMAT 'dollar', "Tags" MULTI_SELECT('eng':blue, 'design':pink), "Task ID" UNIQUE_ID PREFIX 'PRJ')"}</example> <example description="Self-relation (two-step: create database first, then use its data source ID with update_data_source to add self-relations)">{"title": "Tasks", "schema": "CREATE TABLE ("Name" TITLE, "Parent" RELATION('ds_id', DUAL 'Children' 'children'), "Children" RELATION('ds_id', DUAL 'Parent' 'parent'))"}</example>. It is categorised as a Write tool in the Notion MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Notion MCP server in PolicyLayer and add a rule for notion-create-database: 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 Notion. Nothing to install.
notion-create-database 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 notion-create-database 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 notion-create-database. 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.
notion-create-database is provided by the Notion MCP server (@notion-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
