get_configuration

THE RISK

Low Risk

Why get_configuration needs a policy

This tool retrieves and displays configuration information without modifying state. Although it accesses sensitive configuration, the masking of API keys significantly reduces the risk of credential exposure. The action is informational only with no side effects, placing it clearly in the Read category.

From the tool's definition Tool name 'get_configuration' and description 'Show current LNbits configuration' indicate retrieval of configuration state. The phrase 'masked API keys' confirms that sensitive data is filtered, preventing exposure of secrets.

POLICY

How to control get_configuration

PolicyLayer is an MCP gateway — it sits between your AI agents and LNbits MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_configuration:

policy.json

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

get_configuration is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register LNbits MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on get_configuration? +

Register the LNbits MCP Server MCP server in PolicyLayer and add a rule for get_configuration: 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 LNbits MCP Server. Nothing to install.

What risk level is get_configuration? +

What MCP server provides get_configuration? +

get_configuration is provided by the LNbits MCP Server MCP server (lnbits/lnbits-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every LNbits MCP Server tool call.

Start from LNbits MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
