AI agents call get_market_data to retrieve information from Asterdex without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool purely retrieves market information without side effects. It performs data retrieval operations typical of Read category tools. While the server as a whole includes financial and execute-class tools (execute_order, execute_spot_order), this specific tool is limited to querying existing market state.
From the tool's definition Tool name is 'get_market_data' and description states it retrieves 'price, orderbook, funding rates, or 24h stats' — all read-only data queries with no modification, deletion, or execution of orders/code.
Attacks that exploit this kind of access
Get various types of market data. Use this for price, orderbook, funding rates, or 24h stats. It is categorised as a Read tool in the Asterdex MCP Server, which means it retrieves data without modifying state.
Register the Asterdex MCP server in PolicyLayer and add a rule for get_market_data: 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 Asterdex. Nothing to install.
get_market_data 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_market_data 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_market_data. 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_market_data is provided by the Asterdex MCP server (tyranosurasmax/asterdex-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
