Search just the color filters (shortcut for list_effects with kind='filter').
AI agents call list_filters to retrieve information from Media-Editor-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries available color filter options from the media editing system. It performs a search operation (shortcut for list_effects with a specific parameter) to enumerate filters, returning information without modifying, creating, or deleting any data. This is a classic Read operation with minimal security risk.
From the tool's definition Tool name is 'list_filters' and description states it 'Search[es]... color filters', indicating a query/listing operation with no side effects.
