List all Airtable bases accessible with the configured Personal Access Token. Use this to discover available bases and get their IDs.
AI agents call airtable_list_bases to retrieve information from Enhanced Airtable MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates metadata about Airtable bases accessible to the authenticated user. It performs no data modification, deletion, or irreversible action. While it reveals what bases are available (information disclosure risk), this is a standard read operation. Severity is low because listing bases alone does not access sensitive record data or enable destructive operations.
From the tool's definition Tool name 'airtable_list_bases' and description states 'List all Airtable bases' - a retrieval operation with no modification. The verb 'discover' and 'get their IDs' confirm it is a query/fetch operation with no side effects.

Register the Enhanced Airtable MCP Server MCP server in PolicyLayer and add a rule for airtable_list_bases: 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 Enhanced Airtable MCP Server. Nothing to install.
airtable_list_bases 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 airtable_list_bases 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 airtable_list_bases. 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.
airtable_list_bases is provided by the Enhanced Airtable MCP Server MCP server (jordan-huffman/airtable-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
