Get the current price of a token on a specific chain. Requires the token contract address, not symbol. Use relay_get_currencies to find token addresses.\n\nExamples:\n• USDC on Ethereum: chainId=1, address=
AI agents call relay_get_token_price to retrieve information from Relay Protocol MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only fetches and returns current token price information from blockchain networks. It requires only two inputs (chainId and token address) and produces no side effects—no data is created, modified, deleted, or transferred. While it operates in a financial context (cryptocurrency pricing), it does not move money, commit financial obligations, or execute trades.
From the tool's definition Tool name 'relay_get_token_price' and description 'Get the current price of a token' indicate a query operation that retrieves pricing data without modifying, executing, or transferring assets.

Get the current price of a token on a specific chain. Requires the token contract address, not symbol. Use relay_get_currencies to find token addresses.\n\nExamples:\n• USDC on Ethereum: chainId=1, address=. It is categorised as a Read tool in the Relay Protocol MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Relay Protocol MCP Server MCP server in PolicyLayer and add a rule for relay_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 Protocol MCP Server. Nothing to install.
relay_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 relay_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 relay_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.
relay_get_token_price is provided by the Relay Protocol MCP Server MCP server (warengonzaga/relay-protocol-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
