# Sift Docs

Sift is a collaborative, cited brain for humans and agents.

## Choose an interface
- Application memory preview: https://docs.sift.wiki/memory-sdk/preview/
- Hosted MCP for remote agents: https://docs.sift.wiki/connect/hosted-mcp/
- CLI and local MCP: https://docs.sift.wiki/cli/install/

## Safety
- Never send tokens, workspace URLs containing secrets, or private brain content to the docs origin.
- Hosted OAuth happens at the Sift authorization server and in the MCP client.
- Writes require the connected user's capability and explicit intent.
