Get the current USD price of a token from Pyth (primary) with CoinGecko fallback. Useful for agents deciding how much to charge.
AI agents call get_token_price to retrieve information from Agenti without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the financial context of the server (crypto transactions, payments), this tool performs only a read operation—querying price data without side effects. It's informational for decision-making, not a financial transaction itself. The tool cannot move funds or commit financial obligations. Severity is low because misuse by an agent (e.g., requesting wrong token price) cannot cause irreversible harm.
From the tool's definition Tool retrieves current USD price of a token from Pyth/CoinGecko with no modification capability; description states 'Get the current USD price' indicating data retrieval only.
Documented attack patterns abuse exactly the kind of access get_token_price gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Agenti, and nothing reaches the server without passing your rules. This is the rule we recommend for get_token_price:
{
"version": "1",
"default": "deny",
"tools": {
"get_token_price": {}
}
}get_token_price is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Agenti 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 Agenti. 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 Agenti MCP server (nirholas/agenti). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
