AI agents call get_lending_position to retrieve information from Sperax Ecosystem Crypto & DeFI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries lending position information for a user, a read-only operation that retrieves data without side effects. No data is created, modified, or deleted. While the description is minimal, the tool name and context within a DeFi ecosystem clearly indicate a data retrieval function. Severity is low because read operations have minimal blast radius—the worst outcome is information disclosure.
From the tool's definition Tool name 'get_lending_position' and description 'Get a user' indicate retrieval of existing data without modification. The verb 'get' is a read operation.
Documented attack patterns abuse exactly the kind of access get_lending_position gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sperax Ecosystem Crypto & DeFI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_lending_position:
{
"version": "1",
"default": "deny",
"tools": {
"get_lending_position": {}
}
} get_lending_position is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get a user. It is categorised as a Read tool in the Sperax Ecosystem Crypto & DeFI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Sperax Ecosystem Crypto & DeFI MCP Server MCP server in PolicyLayer and add a rule for get_lending_position: 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 Sperax Ecosystem Crypto & DeFI MCP Server. Nothing to install.
get_lending_position 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_lending_position 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_lending_position. 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_lending_position is provided by the Sperax Ecosystem Crypto & DeFI MCP Server MCP server (sperax/sperax-crypto-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Sperax Ecosystem Crypto & DeFI MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
