AI agents invoke quoteCreditPackage to trigger processes or run actions in Stable Baseline. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
quoteCreditPackage can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Quote a credit-package purchase (first half of the human-in-the-loop ritual). Returns quote_token (10-min TTL) plus package + total_aud. Caller must invoke purchaseCreditPackage(quote_token) within the TTL. Use when the user asks to buy credits, purchase credits, top up credits, or add more credits — ALWAYS call this first then purchaseCreditPackage after the user confirms.. It is categorised as a Execute tool in the Stable Baseline MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Stable Baseline MCP server in PolicyLayer and add a rule for quoteCreditPackage: 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 Stable Baseline. Nothing to install.
quoteCreditPackage is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the quoteCreditPackage 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 quoteCreditPackage. 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.
quoteCreditPackage is provided by the Stable Baseline MCP server (https://api.stablebaseline.io/functions/v1/cloud-serve/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
