Get the current price, 24h change, market cap, and volume for any cryptocurrency.
AI agents call price to retrieve information from Cryptosense without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of cryptocurrency market data. It retrieves publicly available information (price, market cap, volume) with no side effects, no code execution, no data modification, and no financial transactions. The blast radius of misuse is minimal—an agent could only retrieve data it is not authorized to see, but cannot execute harmful operations, delete data, or move money.
From the tool's definition Tool name 'price' and description 'Get the current price, 24h change, market cap, and volume for any cryptocurrency' indicate a query operation that retrieves real-time market data without modifying or executing anything.
Attacks that exploit this kind of access
Get the current price, 24h change, market cap, and volume for any cryptocurrency. It is categorised as a Read tool in the Cryptosense MCP Server, which means it retrieves data without modifying state.
Register the Cryptosense MCP server in PolicyLayer and add a rule for 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 Cryptosense. Nothing to install.
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 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 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.
price is provided by the Cryptosense MCP server (josephibra/cryptosense-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
