AI agents call get_prices to retrieve information from MoltLlama without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a data source (DeFiLlama) to return token price information. It is a read-only operation with no side effects—no data is created, modified, deleted, or financial transactions are executed. The scope is limited to retrieving publicly available pricing data.
From the tool's definition Tool description states 'Get current token prices' with no mention of writes, deletions, transactions, or state changes. It retrieves data (prices) based on input symbols.
Attacks that exploit this kind of access
Get current token prices from DeFiLlama. Accepts comma-separated token symbols and resolves them to on-chain addresses. It is categorised as a Read tool in the MoltLlama MCP Server, which means it retrieves data without modifying state.
Register the MoltLlama MCP server in PolicyLayer and add a rule for get_prices: 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 MoltLlama. Nothing to install.
get_prices 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_prices 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_prices. 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_prices is provided by the MoltLlama MCP server (moltllama/moltllama). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
