Retrieve foreign key relationships for a table - use this to understand data connections, build joins, or explore table dependencies
AI agents call get_table_fks to retrieve information from Metabase 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 metadata about foreign key relationships in a database schema. It performs a read-only query operation to understand data structure and connections, with no side effects. While it provides structural information that could inform downstream queries, the tool itself only retrieves and does not execute, modify, or delete data.
From the tool's definition Tool name 'get_table_fks' and description 'Retrieve foreign key relationships' — the verb is explicitly retrieval/query with no modification or execution capability.
Attacks that exploit this kind of access
Retrieve foreign key relationships for a table - use this to understand data connections, build joins, or explore table dependencies. It is categorised as a Read tool in the Metabase MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Metabase MCP Server MCP server in PolicyLayer and add a rule for get_table_fks: 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 Metabase MCP Server. Nothing to install.
get_table_fks 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_table_fks 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_table_fks. 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_table_fks is provided by the Metabase MCP Server MCP server (thangnm93/metabase-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
