Calculate the linear pricing curve for a Ponzu presale given a target ETH raise. Returns start price, end price (10x start), and encoded pricing data. Formula: 690,000 tokens sold on a linear curve. Minimum raise: 3 ETH mainnet, 0.1 ETH sepolia.

AI agents invoke ponzu_calc_pricing to trigger processes or run actions in Ponzu App. 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.
ponzu_calc_pricing 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.
Calculate the linear pricing curve for a Ponzu presale given a target ETH raise. Returns start price, end price (10x start), and encoded pricing data. Formula: 690,000 tokens sold on a linear curve. Minimum raise: 3 ETH mainnet, 0.1 ETH sepolia.. It is categorised as a Execute tool in the Ponzu App MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Ponzu App MCP server in PolicyLayer and add a rule for ponzu_calc_pricing: 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 Ponzu App. Nothing to install.
ponzu_calc_pricing 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 ponzu_calc_pricing 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 ponzu_calc_pricing. 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.
ponzu_calc_pricing is provided by the Ponzu App MCP server (PonzuTech/ponzu_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
