Get metadata for a CAS table (row count, column count, size, etc.).
AI agents call get_castable_info 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.
This tool retrieves metadata about a CAS (Cloud Analytic Services) table without modifying, executing code, or triggering operations. It is a simple query operation returning informational attributes. Low severity because metadata exposure is minimal risk, and high confidence because the description is clear and explicit about the read-only nature of the operation.
From the tool's definition Tool name 'get_castable_info' and description 'Get metadata for a CAS table (row count, column count, size, etc.)' indicate retrieval of table metadata only.
Documented attack patterns abuse exactly the kind of access get_castable_info 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_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_castable_info": {}
}
}get_castable_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get metadata for a CAS table (row count, column count, size, etc.). 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_info: 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_info 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_info 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_info. 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_info 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.
Free to start. No card required.
