+# BrainKB Skills
+This skill provides tools for ingesting, querying, and exploring **BrainKB (Brain Knowledgebase)**. It preferentially uses the **`brainkb_mcp`** server (`brainkb_mcp/`) when available, enabling direct MCP-based interaction. If the MCP server is unavailable, equivalent operations are performed through the BrainKB REST API using `curl` (see below).
