What get_nostr_identity does on Lightning Wallet
AI agents call get_nostr_identity to retrieve information from Lightning Wallet without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get_nostr_identity is rated Low
This tool retrieves identity data (nostr identity associated with an agent) with no side effects. It is a read-only operation that queries existing information. The incomplete description ('Get the agent') and lack of mutation, execution, or financial semantics place it firmly in the Read category. Severity is low because identity retrieval poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'get_nostr_identity' and description 'Get the agent' indicate data retrieval. The tool fetches identity information without modifying, deleting, or executing operations.
Attacks that exploit this kind of access
The rule that runs get_nostr_identity safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Lightning Wallet, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_nostr_identity, this is the rule to start with:
get_nostr_identity is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Lightning Wallet, apply this rule, and every get_nostr_identity call is checked against it from then on.
