List all budgets associated with your firm.
AI agents call list_budgets to retrieve information from Standard Metrics 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 and displays budget information for a firm. It is a read-only operation with no side effects—it neither modifies data, executes code, deletes information, nor commits financial transactions. The blast radius is minimal: exposure of this tool to an AI agent could leak budget visibility but cannot cause financial transactions, data loss, or system compromise.
From the tool's definition Tool name 'list_budgets' and description 'List all budgets associated with your firm' indicate a retrieval operation that queries existing data without modification, deletion, or execution of external processes.
Documented attack patterns abuse exactly the kind of access list_budgets gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Standard Metrics MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_budgets:
{
"version": "1",
"default": "deny",
"tools": {
"list_budgets": {}
}
}list_budgets is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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