Get the essential databases for the provided subscription Id
AI agents call get-essential-databases to retrieve information from Redis Cloud API MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves database information based on a subscription ID. It performs a simple query/fetch operation without creating, modifying, deleting, or executing any actions. The 'get-' pattern and 'Get the essential databases' language confirm a read-only operation. Severity is low because reading database metadata poses minimal risk—it may expose information but does not alter state or trigger external actions.
From the tool's definition Tool name uses 'get-' prefix and description states 'Get the essential databases' - a retrieval operation with no modification or execution. No side effects indicated.
Documented attack patterns abuse exactly the kind of access get-essential-databases gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Redis Cloud API MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get-essential-databases:
{
"version": "1",
"default": "deny",
"tools": {
"get-essential-databases": {}
}
}get-essential-databases is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the essential databases for the provided subscription Id. It is categorised as a Read tool in the Redis Cloud API MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Redis Cloud API MCP Server MCP server in PolicyLayer and add a rule for get-essential-databases: 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 Redis Cloud API MCP Server. Nothing to install.
get-essential-databases 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-essential-databases 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-essential-databases. 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-essential-databases is provided by the Redis Cloud API MCP Server MCP server (redis/mcp-redis-cloud). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
