Get all active blockers, optionally filtered by project.
AI agents call get_active_blockers to retrieve information from Studio Catharsis Universal Project Coordinator MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves blocker information from a shared project state without creating, modifying, or deleting any data. It is a simple query operation analogous to 'list' or 'fetch', which are canonical Read operations. Even if an AI agent misuses it by querying all blockers, the worst outcome is information disclosure with no operational damage.
From the tool's definition Tool name is 'get_active_blockers' and description states 'Get all active blockers, optionally filtered by project.' The verb 'Get' and phrase 'optionally filtered' indicate a read-only query operation with no side effects.
