Get detailed information about a specific table including all fields
AI agents call describe_table 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 a table structure (fields and properties) without creating, modifying, deleting, or executing any operations. It is a pure read operation with no side effects, making it the least risky category.
From the tool's definition Tool name 'describe_table' and description 'Get detailed information about a specific table including all fields' indicate a retrieval operation with no modification or deletion of data.
Documented attack patterns abuse exactly the kind of access describe_table 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_table:
{
"version": "1",
"default": "deny",
"tools": {
"describe_table": {}
}
}describe_table is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get detailed information about a specific table including all fields. 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_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 Airtable MCP. Nothing to install.
describe_table 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_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.
Set action: deny in the PolicyLayer policy for describe_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.
describe_table 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.
