AI agents call hyperliquid_list_spot_tokens 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_list_spot_tokens 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.

Use this when you need to list or search spot tokens available on Hyperliquid L1 DEX. Returns all 454 spot tokens with full metadata including token name, symbol, tokenId, index, decimals, and wei conversion factors. Returns for each token: 1. name: token display name (e.g. "PURR", "HFUN") 2. tokenId: unique hex token identifier on Hyperliquid 3. index: integer index in the spot meta registry 4. decimals: token decimal precision (szDecimals) 5. weiDecimals: wei-level decimal precision for raw amounts Optional filter: pass "search" to filter tokens by name/symbol substring match (case-insensitive). Returns all tokens if no search term provided. Example output: { tokens: [{ name: "PURR", tokenId: "0xc4bf3f...", index: 1, decimals: 0, weiDecimals: 8 }], count: 454 } Use this to discover which spot tokens exist on Hyperliquid before querying prices or balances. Essential for building trading interfaces or token lookups. Do NOT use for perps/futures data -- use hyperliquid_get_perp_markets instead. Do NOT use for token prices on CEX/CoinGecko -- use token_get_price instead. Do NOT use for wallet portfolio across chains -- use wallet_get_portfolio instead. Do NOT use for Hyperliquid vault data -- use hyperliquid_get_vaults instead.. 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_list_spot_tokens: 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_list_spot_tokens 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_list_spot_tokens 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_list_spot_tokens. 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_list_spot_tokens 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.
