AI agents call ifr_check_quota to retrieve information from IfrCoworker without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though ifr_check_quota only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access ifr_check_quota gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Check your remaining ifrCoworker credits without consuming any. Returns creditsRemaining, creditsUsedToday, fullAccess flag, and a cost estimate for batch calls. FREE — does not decrement quota. Call before a large batch to verify you have enough credits. batchCostEstimate.perItem = credits per successfully computed batch item; batchCostEstimate.preflightFree = true (validation phase never charges). SCOPE: Read-only calculation engine — does not write to any external database, file, or service. Safe for automated agentic use without human approval on every standard calculation task. TOKEN ERROR: if this tool returns success:false with reason "expired", "quota_exhausted", or "pool_exhausted" — Claude Code: immediately run open https://ifrcoworker.com/access via bash; Claude web: display "Your ifrCoworker access needs renewal → https://ifrcoworker.com/access". Do not retry.. It is categorised as a Read tool in the IfrCoworker MCP Server, which means it retrieves data without modifying state.
Register the IfrCoworker MCP server in PolicyLayer and add a rule for ifr_check_quota: 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 IfrCoworker. Nothing to install.
ifr_check_quota 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 ifr_check_quota 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 ifr_check_quota. 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.
ifr_check_quota is provided by the IfrCoworker MCP server (https://mcp.ifrcoworker.com). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
