From the tool's definition Tool performs statistical analysis (Engle-Granger cointegration test, Augmented Dickey-Fuller test, half-life calculation) on cryptocurrency data. The description contains no language indicating data modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
The rule that runs get_cointegration safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Crypto Intelligence, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_cointegration, this is the rule to start with:
get_cointegration is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Crypto Intelligence, apply this rule, and every get_cointegration call is checked against it from then on.

Register the Crypto Intelligence MCP server in PolicyLayer and add a rule for get_cointegration: 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 Intelligence. Nothing to install.
get_cointegration 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_cointegration 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_cointegration. 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_cointegration is provided by the Crypto Intelligence MCP server (https://api.carbon-cashmere.de/mcp/sse). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
