AI agents call get_quote 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.
This tool retrieves stock market data without modifying, executing code, deleting data, or moving money. It is a read-only data retrieval operation with minimal blast radius if misused—worst case being irrelevant or incorrect financial lookups that could inform poor decisions but cause no direct system damage or data loss.

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_quote:
{
"version": "1",
"default": "deny",
"tools": {
"get_quote": {}
}
}get_quote is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_quote. 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_quote: 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_quote 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_quote 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_quote. 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_quote 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.
Free to start. No card required.
