Find positions that can be liquidated (health factor < 1)
AI agents call get_liquidatable_positions 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 retrieves data about liquidatable positions without executing liquidations or modifying state. While the information could enable harmful actions (liquidations), the tool itself performs only read operations.
From the tool's definition Tool name 'get_liquidatable_positions' and description 'Find positions that can be liquidated' indicate a query/retrieval operation. The verb 'Find' and absence of modification language confirm this is informational lookup.
Documented attack patterns abuse exactly the kind of access get_liquidatable_positions 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_liquidatable_positions:
{
"version": "1",
"default": "deny",
"tools": {
"get_liquidatable_positions": {}
}
} get_liquidatable_positions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Find positions that can be liquidated (health factor < 1). 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_liquidatable_positions: 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_liquidatable_positions 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_liquidatable_positions 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_liquidatable_positions. 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_liquidatable_positions 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.
