Gets details of a specific database
AI agents call get-database to retrieve information from Nile without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves database metadata or configuration details without modifying, deleting, or executing operations. It is a straightforward read operation similar to other Read category tools on this server like 'list-databases' and 'list-resources'. The blast radius of misuse is minimal—an unauthorized query would leak database details but cause no data loss or operational damage.
From the tool's definition Tool name 'get-database' and description 'Gets details of a specific database' indicate a retrieval operation with no modification or deletion.
Documented attack patterns abuse exactly the kind of access get-database gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Nile, and nothing reaches the server without passing your rules. This is the rule we recommend for get-database:
{
"version": "1",
"default": "deny",
"tools": {
"get-database": {}
}
}get-database is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Gets details of a specific database. It is categorised as a Read tool in the Nile MCP Server, which means it retrieves data without modifying state.
Register the Nile MCP server in PolicyLayer and add a rule for get-database: 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 Nile. Nothing to install.
get-database 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-database 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-database. 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-database is provided by the Nile MCP server (@niledatabase/nile-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Nile, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
