WHEN AI AGENTS USE THIS TOOL

AI agents use create_field to create or modify resources in Airtable. 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.

WHY ENFORCE A POLICY ON CREATE_FIELD

Without a policy, an AI agent could call create_field repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Airtable.

RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

airtable.yaml 
tools:
  create_field:
    rules:
      - action: allow
        rate_limit:
          max: 30
          window: 60

FREQUENTLY ASKED QUESTIONS

What does the create_field tool do?

Add a new field to a table. It is categorised as a Write tool in the Airtable 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_field?

Add a rule in your Intercept YAML policy under the tools section for create_field. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Airtable MCP server.

What risk level is create_field?

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

Can I rate-limit create_field?

Yes. Add a rate_limit block to the create_field rule in your Intercept 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_field completely?

Set action: deny in the Intercept policy for create_field. 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_field?

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