AI agents call hyperliquid_get_spot_markets to retrieve information from Hyperliquid Spot API without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though hyperliquid_get_spot_markets only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Returns merged token metadata + real-time market context for every active spot market. Returns for each market: 1. name: token name (e.g. "PURR/USDC") 2. coin: base token symbol 3. tokenId: unique token identifier 4. markPx: current mark/mid price in USDC 5. midPx: mid price between best bid and ask 6. prevDayPx: previous day closing price 7. dayNtlVlm: 24h notional volume in USDC 8. change24h: percentage price change over 24 hours Sortable by: "volume" (default, highest 24h volume first), "change" (biggest movers first), "name" (alphabetical). Example output: { markets: [{ name: "PURR/USDC", markPx: "0.0234", dayNtlVlm: "1250000", change24h: 5.32 }], count: 120 } Use this to find trending spot tokens, check current prices, or scan for high-volume trading opportunities on Hyperliquid.

It is categorised as a Read tool in the Hyperliquid Spot API MCP Server, which means it retrieves data without modifying state.
Register the Hyperliquid Spot API MCP server in PolicyLayer and add a rule for hyperliquid_get_spot_markets: 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 Spot API. Nothing to install.
hyperliquid_get_spot_markets 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 hyperliquid_get_spot_markets 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 hyperliquid_get_spot_markets. 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.
hyperliquid_get_spot_markets is provided by the Hyperliquid Spot API MCP server (https://hl-spot.api.klymax402.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
