AI agents call get_table_properties to retrieve information from IcebergMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves table properties metadata from an Iceberg data lakehouse. The 'get_' prefix and context of querying metadata indicate this is a read-only operation with no side effects. While the tool description is empty, the naming pattern and sibling tools strongly suggest metadata retrieval rather than modification or execution.
From the tool's definition Tool name 'get_table_properties' and sibling tools (get_iceberg_tables, get_namespaces, get_table_partitions, get_table_schema) all use the 'get_' prefix, which is a strong convention for read-only retrieval operations.
Documented attack patterns abuse exactly the kind of access get_table_properties gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and IcebergMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_table_properties:
{
"version": "1",
"default": "deny",
"tools": {
"get_table_properties": {}
}
}get_table_properties is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_table_properties. It is categorised as a Read tool in the IcebergMCP MCP Server, which means it retrieves data without modifying state.
Register the Iceberg MCP server in PolicyLayer and add a rule for get_table_properties: 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 IcebergMCP. Nothing to install.
get_table_properties 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_properties 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_properties. 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_properties is provided by the Iceberg MCP server (ryft-io/iceberg-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
