get_user_id
AI agents call get_user_id 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.
The tool appears to retrieve or query user identity information with no apparent side effects. While the empty description reduces confidence slightly, the naming convention strongly suggests a Read operation. Even if this retrieves user context for subsequent operations, retrieval itself is non-destructive and fits the Read category.
From the tool's definition Tool name 'get_user_id' indicates retrieval of a user identifier. No description provided to suggest write, delete, execute, or financial operations.
Attacks that exploit this kind of access
get_user_id. 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 get_user_id: 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.
get_user_id 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_user_id 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_user_id. 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_user_id 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.
