AI agents call list_protocols 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 retrieves and presents information (TVL, category, change metrics) about DeFi protocols. It has no side effects and performs no data modification, state changes, code execution, or irreversible operations. The blast radius of misuse is minimal—the worst case is returning large or filtered datasets. This is a pure Read operation.
From the tool's definition Tool name is 'list_protocols' and description states it 'List DeFi protocols' — a retrieval operation that queries and returns data about DeFi protocols without modification. No action verbs like create, update, delete, or execute are present.
Attacks that exploit this kind of access
List DeFi protocols with TVL, category, and change metrics. Filters to supported chains (Base + Ethereum) by default. 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 list_protocols: 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.
list_protocols 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 list_protocols 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 list_protocols. 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.
list_protocols 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.
list_protocols is one line of MoltLlama's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
