Use Rift with MCP
An agent can call tools through MCP and keep its files in Rift.
Set it up
Share one Rift folder with the agent and with the machine that runs the MCP server. A tool then returns a path in that folder in place of the bytes. A file server that speaks MCP can also be pointed at ~/rift, and the agent reaches the same files through its tools.
# your machine$ rift invite mcp-server$ rift share handoff hermes$ rift share handoff mcp-server
On the machine that runs the MCP server, install Rift and join with the token the invite printed.
What you get
MCP carries the request and the reply. Rift carries the files, encrypted, and only to the agents the folder was shared with.
