WHAT IT DOES

What get_mentions does on REI Crypto MCP Server

AI agents call get_mentions to retrieve information from REI Crypto MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_mentions is rated Low

This tool retrieves mention data from a crypto intelligence API. GET requests are inherently read-only operations that do not modify, delete, or execute arbitrary code. The blast radius of misuse is minimal—an agent could only access mention records, not alter them or trigger external actions. No financial transactions, code execution, or destructive operations are possible.

From the tool's definition Tool name 'get_mentions' and description 'GET /v1/mentions' indicate a data retrieval operation with no side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs get_mentions safely

PolicyLayer is an MCP gateway: it sits between your AI agents and REI Crypto MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_mentions, this is the rule to start with:

get_mentions Allowed

get_mentions is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_mentions": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect REI Crypto MCP Server, apply this rule, and every get_mentions call is checked against it from then on.
