WHAT IT DOES

WHY IT NEEDS A POLICY

Why wallet_add_network needs a policy

This tool modifies wallet configuration by adding custom networks and API URLs. While reversible (networks can be removed or reconfigured), the ability to inject custom API URLs into a Bitcoin wallet creates a high-severity risk: a compromised AI agent could redirect transaction communication to attacker-controlled endpoints, enabling man-in-the-middle attacks on subsequent financial operations.

From the tool's definition Tool name 'wallet_add_network' and description 'Add a custom network with custom API URLs' indicate creation/modification of network configuration data. The verb 'Add' and action of configuring custom API endpoints represent reversible data modification.
