Describe Airtable base or table schema. Use detailLevel to optimize context usage: - tableIdentifiersOnly: Only table IDs and names (minimal) - identifiersOnly: Table, field, and view IDs and names - full: Complete details including field types and options (default)
AI agents call describe to retrieve information from Airtable MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about Airtable base and table structures without creating, modifying, or deleting any records or data. It is a pure information-gathering operation that returns schema details at varying levels of completeness.
From the tool's definition Tool name 'describe' and description 'Describe Airtable base or table schema' indicate data retrieval with no modification. The detailLevel parameter offers different verbosity options for querying schema information, all read-only operations.
Documented attack patterns abuse exactly the kind of access describe 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 describe:
{
"version": "1",
"default": "deny",
"tools": {
"describe": {}
}
}describe is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Describe Airtable base or table schema. Use detailLevel to optimize context usage: - tableIdentifiersOnly: Only table IDs and names (minimal) - identifiersOnly: Table, field, and view IDs and names - full: Complete details including field types and options (default). It is categorised as a Read tool in the Airtable MCP MCP Server, which means it retrieves data without modifying state.
Register the Airtable MCP server in PolicyLayer and add a rule for describe: 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.
describe is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the describe 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 describe. 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.
describe 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.
