Process a payment via Cardiac NWOPaymentProcessor smart contract (0x4afa...)
Part of the Srv D7aoqmh5pdvs7391dcqg MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call cardiac_payment_process to retrieve information from Srv D7aoqmh5pdvs7391dcqg 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 cardiac_payment_process 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.

Process a payment via Cardiac NWOPaymentProcessor smart contract (0x4afa...). It is categorised as a Read tool in the Srv D7aoqmh5pdvs7391dcqg MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for cardiac_payment_process. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Srv D7aoqmh5pdvs7391dcqg MCP server.
cardiac_payment_process 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 cardiac_payment_process rule in your Intercept 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 Intercept policy for cardiac_payment_process. 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.
cardiac_payment_process is provided by the Srv D7aoqmh5pdvs7391dcqg MCP server (ciprianpater/srv-d7aoqmh5pdvs7391dcqg). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
