Get the current USD price of a token on a specific chain. For just the price, use this tool. For full fundamentals (marketCap, volume, liquidity, chart), use get_token_details instead.

AI agents call get_token_price to retrieve information from Relay 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 pricing information without modifying any state, executing code, or creating financial obligations. While the server context involves blockchain transactions and swaps, this specific tool is a passive lookup. The blast radius of misuse is minimal—an agent could request prices for tokens, but cannot execute trades, transfer funds, or delete data.
From the tool's definition Tool name 'get_token_price' and description explicitly states 'Get the current USD price of a token on a specific chain' — a pure query operation with no side effects.
Attacks that exploit this kind of access
Get the current USD price of a token on a specific chain. For just the price, use this tool. For full fundamentals (marketCap, volume, liquidity, chart), use get_token_details instead. For fee estimates on a specific bridge/swap route, use estimate_fees — this tool is for standalone token pricing only. It is categorised as a Read tool in the Relay MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Relay MCP Server MCP server in PolicyLayer and add a rule for get_token_price: 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 Relay MCP Server. Nothing to install.
get_token_price 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_token_price 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_token_price. 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_token_price is provided by the Relay MCP Server MCP server (relayprotocol/relay-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
