Why share_view needs a policy

This tool modifies the sharing state of a view (enabling or disabling public access), which is a reversible write operation. However, it carries high severity because enabling a public share link could expose potentially sensitive database content to anyone with the URL, representing a significant data exposure risk if misused by an AI agent.

From the tool's definition Enable or disable public share link for a view. Returns the share URL when enabled.

POLICY

How to control share_view

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 share_view:

policy.json

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

share_view 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.

Questions about share_view

What does the share_view tool do? +

Enable or disable public share link for a view. Returns the share URL when enabled. 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 share_view? +

Register the Teable MCP Server MCP server in PolicyLayer and add a rule for share_view: 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 share_view? +

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

Can I rate-limit share_view? +

Yes. Add a rate_limit block to the share_view 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 share_view completely? +

Set action: deny in the PolicyLayer policy for share_view. 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 share_view? +

share_view 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.
