List Capabilities

Immutable Catalog Entry

This descriptor comes from the active versioned Portal catalog.

READffmpeg.list_capabilities

• Contract tier: agent_ready
• Risk: read
• Catalog version: 2026-07-12.3
• Descriptor hash: 0bb7a7bd51a9576b39892b897e90dfbed336f6b9eedce6a6d588af8aa12515a6

Use this to understand the FFmpeg MCP surface by category and risk. Set include_descriptors to true when the caller needs the complete, lossless, versioned ToolManifest for catalog ingestion; it performs no media work.
