Get the current price of a token in USDC by running a zero-cost quote. Resolves token symbols (SOL, ETH) to addresses automatically. Does NOT require an API key — only auth token. Args: - token (string): Token symbol (e.g.
AI agents call tm_get_price to retrieve information from Truemarkets without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
tm_get_price performs a data retrieval operation only. It queries current token pricing information and returns it without altering state, executing code, or committing financial transactions. While it exists in a financial trading context, the tool itself is purely informational (Read). The zero-cost nature and lack of any destructive, write, or transactional elements confirm this classification.
From the tool's definition Tool description states it 'Get[s] the current price of a token' and 'running a zero-cost quote', which retrieves market data without side effects. No modifications, deletions, transfers, or executions occur.

Register the Truemarkets MCP server in PolicyLayer and add a rule for tm_get_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 Truemarkets. Nothing to install.
tm_get_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 tm_get_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 tm_get_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.
tm_get_price is provided by the Truemarkets MCP server (jun229/tm-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
