create_comment

Create a comment on an Airtable record. Requires data.recordComments:write scope.

How to control create_comment ↓

AI agents use create_comment to create or update resources in Airtable MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Airtable MCP environment.

Medium Risk

This tool creates new data (comments) on Airtable records in a reversible manner. While comments can typically be edited or deleted later, the primary action is additive/modifying. It does not execute arbitrary code, delete data irreversibly, or move money. The 'write' scope and creation semantics place it in the Write category.

From the tool's definition Tool name is 'create_comment' and description states it will 'Create a comment on an Airtable record' with 'recordComments:write scope', indicating data modification.

Documented attack patterns abuse exactly the kind of access create_comment gives an agent:

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_comment": {
      "limits": [
        {
          "counter": "create_comment_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_comment 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.

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

What does the create_comment tool do? +

Create a comment on an Airtable record. Requires data.recordComments:write scope. It is categorised as a Write tool in the Airtable MCP 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_comment? +

Register the Airtable MCP server in PolicyLayer and add a rule for create_comment: 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 Airtable MCP. Nothing to install.

What risk level is create_comment? +

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

Can I rate-limit create_comment? +

Yes. Add a rate_limit block to the create_comment 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_comment completely? +

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

create_comment is provided by the Airtable MCP server (rashidazarang/airtable-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Airtable MCP tool call.
