+tagline: Local-first memory for OpenCode and any MCP-compatible AI agent
+description: >
+  Gives OpenCode durable memory across chats through its native MCP support.
+  Ships a ready-to-copy OpenCode configuration and five-tool starter profile
+  for remembering, recalling, inspecting, correcting, and explicitly erasing
+  local memory. No Lians account, API key, model download, or cloud service is
+  required; memory stays in a local SQLite database and can be shared with
+  other compatible agents.
