AI agents call get_castable_data to retrieve information from SAS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name indicates a read operation that fetches castable data, likely for inspection or analysis purposes. Without a description, confidence is moderately reduced, but the naming pattern and context of similar read-only tools on the server strongly suggest this retrieves data without modification. Low severity reflects typical read-only operations on a SAS analytics platform.
From the tool's definition Tool name 'get_castable_data' suggests retrieval of data; no description provided, but naming convention and sibling tools (get_castable_columns, get_castable_info, get_job_log, get_job_status, get_report, get_report_image) all follow a retrieval pattern.
Documented attack patterns abuse exactly the kind of access get_castable_data gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SAS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_castable_data:
{
"version": "1",
"default": "deny",
"tools": {
"get_castable_data": {}
}
}get_castable_data is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_castable_data. It is categorised as a Read tool in the SAS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the SAS MCP Server MCP server in PolicyLayer and add a rule for get_castable_data: 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 SAS MCP Server. Nothing to install.
get_castable_data 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_castable_data 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_castable_data. 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_castable_data is provided by the SAS MCP Server MCP server (sassoftware/sas-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SAS MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
