THE RISK

Medium Risk

Why create_table needs a policy

The create_table tool creates new database tables, which is a write operation that modifies the database schema. While reversible (can be deleted via delete_table), it irreversibly commits new structure into the base and could impact dependent views or queries if not managed carefully. Classified as Write rather than Destructive because table creation itself is reversible and does not destroy existing data.

From the tool's definition Tool name is 'create_table' with description 'Create a new table in a base'. This creates new data structures in the database reversibly.

POLICY

How to control create_table

PolicyLayer is an MCP gateway — it sits between your AI agents and Teable MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_table:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_table": {
      "limits": [
        {
          "counter": "create_table_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_table stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Teable MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about create_table

What does the create_table tool do? +

Create a new table in a base. It is categorised as a Write tool in the Teable MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_table? +

Register the Teable MCP Server MCP server in PolicyLayer and add a rule for create_table: 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 Teable MCP Server. Nothing to install.

What risk level is create_table? +

create_table is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_table? +

Yes. Add a rate_limit block to the create_table 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.

How do I block create_table completely? +

Set action: deny in the PolicyLayer policy for create_table. 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.

What MCP server provides create_table? +

create_table is provided by the Teable MCP Server MCP server (ltphat2204/teable-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Teable MCP Server tool call.

Start from Teable MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
