Get Velar protocol contract addresses
AI agents call velar_get_contract_addresses to retrieve information from Stacks AI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a simple data retrieval tool that fetches contract addresses from the Velar protocol. It performs a read-only query with no side effects, no code execution, and no financial or destructive operations. The severity is low because contract addresses are public information and misuse would only affect the AI agent's ability to interact with the protocol, not cause direct harm to user assets or data.
From the tool's definition Tool name 'velar_get_contract_addresses' and description 'Get Velar protocol contract addresses' indicate a retrieval operation that queries and returns contract address data without modifying state or triggering transactions.
