Summary of recent workspace usage (calls, providers, cost) for the current billing period.
AI agents call get_usage_summary to retrieve information from APIClaw without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries usage statistics and cost data for the current billing period. It has no side effects—it does not create, modify, delete, or execute operations. While it accesses billing/cost information, it is purely informational and read-only.
From the tool's definition Tool name 'get_usage_summary' and description 'Summary of recent workspace usage (calls, providers, cost) for the current billing period' indicate retrieval of usage metrics and billing information without modification.
Documented attack patterns abuse exactly the kind of access get_usage_summary gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and APIClaw, and nothing reaches the server without passing your rules. This is the rule we recommend for get_usage_summary:
{
"version": "1",
"default": "deny",
"tools": {
"get_usage_summary": {}
}
}get_usage_summary is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Summary of recent workspace usage (calls, providers, cost) for the current billing period. It is categorised as a Read tool in the APIClaw MCP Server, which means it retrieves data without modifying state.
Register the APIClaw MCP server in PolicyLayer and add a rule for get_usage_summary: 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 APIClaw. Nothing to install.
get_usage_summary 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_usage_summary 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_usage_summary. 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_usage_summary is provided by the APIClaw MCP server (nordsym/apiclaw). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from APIClaw, 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.
