AI agents call get_quotes to retrieve information from Sahmk without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves stock market quotation data with no indication of side effects, data modification, or destructive capabilities. Even with an empty description, the naming convention and server purpose (querying market data) strongly suggest a simple data retrieval operation. No financial transactions, code execution, or data modification is implied.
From the tool's definition Tool name 'get_quotes' and server context (Saudi market data, stock quotes) indicate data retrieval. Description is empty, but sibling tools like 'get_quote', 'get_market_summary', and 'get_historical' establish the pattern of read-only market data queries on…
Documented attack patterns abuse exactly the kind of access get_quotes gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sahmk, and nothing reaches the server without passing your rules. This is the rule we recommend for get_quotes:
{
"version": "1",
"default": "deny",
"tools": {
"get_quotes": {}
}
}get_quotes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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