AI agents call get_spot_metadata to retrieve information from Hyperliquid Info without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves metadata about spot trading pairs—static exchange information with no side effects, reversibility concerns, or financial transaction capabilities. Consistent with other 'get_*' tools on the server that perform informational queries. Low severity as metadata access alone cannot cause harm.
From the tool's definition Tool name 'get_spot_metadata' indicates data retrieval. The pattern of sibling tools (get_candles_snapshot, get_l2_snapshot, get_perp_metadata, get_user_open_orders) are all Read operations querying market/user data from Hyperliquid exchange.
Documented attack patterns abuse exactly the kind of access get_spot_metadata gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Hyperliquid Info, and nothing reaches the server without passing your rules. This is the rule we recommend for get_spot_metadata:
{
"version": "1",
"default": "deny",
"tools": {
"get_spot_metadata": {}
}
}get_spot_metadata is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_spot_metadata. It is categorised as a Read tool in the Hyperliquid Info MCP Server, which means it retrieves data without modifying state.
Register the Hyperliquid Info MCP server in PolicyLayer and add a rule for get_spot_metadata: 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 Hyperliquid Info. Nothing to install.
get_spot_metadata 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_spot_metadata 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_spot_metadata. 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_spot_metadata is provided by the Hyperliquid Info MCP server (kukapay/hyperliquid-info-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Hyperliquid Info, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
