List all available Airtable bases
AI agents call list_bases to retrieve information from MCP Airtable Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation to enumerate available Airtable bases. It has no side effects, does not modify any data, and merely returns a list of existing bases accessible to the user. This is a standard information retrieval operation with minimal risk of misuse, even by an unreliable agent, as it only exposes what bases exist without enabling destructive or financial actions.
From the tool's definition Tool name 'list_bases' and description 'List all available Airtable bases' indicate a query operation that retrieves information without modifying data.
Attacks that exploit this kind of access
List all available Airtable bases. It is categorised as a Read tool in the MCP Airtable Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Airtable Server MCP server in PolicyLayer and add a rule for 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 MCP Airtable Server. Nothing to install.
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 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 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.
list_bases is provided by the MCP Airtable Server MCP server (marchi-lau/mcp-airtable). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
