discover_apis
AI agents call discover_apis to retrieve information from Open Assembly without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Without an explicit description, classify based on context: the server provides read-only access to legislative data, and 'discover_apis' most likely enumerates available endpoints or schema information rather than executing commands, modifying data, or performing financial operations. This fits the Read category as a non-destructive informational query.
From the tool's definition Tool name 'discover_apis' suggests API discovery/exploration functionality. Empty description limits specificity.
