What get_protocols does on Defillama
AI agents call get_protocols to retrieve information from Defillama without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get_protocols is rated Low
This tool performs a simple data retrieval operation ('List all protocols') and returns informational metrics (TVL values). It has no side effects, does not execute code, does not modify data, and does not involve financial transactions. The read-only nature and low blast radius (retrieving public DeFi protocol statistics) clearly place it in the Read category with low severity.
From the tool's definition Tool name 'get_protocols' and description 'List all protocols on defillama along with their tvl' indicate a query operation that retrieves and displays data without modification.
Attacks that exploit this kind of access
The rule that runs get_protocols safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Defillama, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_protocols, this is the rule to start with:
get_protocols is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Defillama, apply this rule, and every get_protocols call is checked against it from then on.
Questions about get_protocols
List all protocols on defillama along with their tvl. It is categorised as a Read tool in the Defillama MCP Server, which means it retrieves data without modifying state.
Register the Defillama MCP server in PolicyLayer and add a rule for get_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 Defillama. Nothing to install.
get_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 get_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 get_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.
get_protocols is provided by the Defillama MCP server (@nic0xflamel/defillama-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
