AI agents call get_platform_limits to retrieve information from Kifly — Agentic Commerce & Payments 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 get_platform_limits 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 get_platform_limits 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.
Returns the current platform-enforced cart limits: max_item_quantity (per-line-item ceiling), max_cart_total_cents, and max_cart_total_usd. Call this once at session start before building a large cart so you can quote limits to the buyer proactively rather than discovering them via errors. The limits are operator-configurable; always read them at runtime rather than hardcoding.. It is categorised as a Read tool in the Kifly — Agentic Commerce & Payments MCP Server, which means it retrieves data without modifying state.
Register the Kifly — Agentic Commerce & Payments MCP server in PolicyLayer and add a rule for get_platform_limits: 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 Kifly — Agentic Commerce & Payments. Nothing to install.
get_platform_limits 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_platform_limits 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_platform_limits. 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_platform_limits is provided by the Kifly — Agentic Commerce & Payments MCP server (https://kifly.io/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
