Fetch basic metrics for a specific fund by ID from Cryptorank API.
AI agents call get_fund_basic to retrieve information from Crypto Funds MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves structured cryptocurrency fund data from an external API without creating, modifying, deleting, or executing any operations. It has no side effects beyond querying and returning information. The blast radius of misuse is minimal—an agent could only view fund data it shouldn't have access to, which is a low-severity information disclosure risk.
From the tool's definition Tool name 'get_fund_basic' and description 'Fetch basic metrics for a specific fund by ID' indicate data retrieval with no modification. The verb 'Fetch' and the operation of retrieving metrics are inherently read-only operations.
Attacks that exploit this kind of access

Register the Crypto Funds MCP server in PolicyLayer and add a rule for get_fund_basic: 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 Crypto Funds MCP. Nothing to install.
get_fund_basic 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_fund_basic 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_fund_basic. 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.
