Get complete base schema including all tables and fields. For large schemas, returns a cache ID to fetch data in chunks.
AI agents call get_base_schema to retrieve information from 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 only retrieves schema information (table and field definitions) without side effects. It is a read-only query operation that returns existing metadata about the Airtable base structure. The mention of 'cache ID to fetch data in chunks' confirms it is a retrieval mechanism, not a write or execute operation.
From the tool's definition Tool description states it 'Get[s] complete base schema including all tables and fields' with no mention of modification, deletion, or execution. The function retrieves and queries structural metadata.
Attacks that exploit this kind of access
Get complete base schema including all tables and fields. For large schemas, returns a cache ID to fetch data in chunks. It is categorised as a Read tool in the Airtable MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Airtable MCP Server MCP server in PolicyLayer and add a rule for get_base_schema: 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 Server. Nothing to install.
get_base_schema 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 get_base_schema 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 get_base_schema. 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.
get_base_schema is provided by the Airtable MCP Server MCP server (loticdigital/airtable-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
