DriftOS MCP Server

MCP server for semantic conversation routing with DriftOS.

What is this?

An MCP (Model Context Protocol) server that lets any MCP-compatible client (Claude Desktop, Cursor, etc.) use DriftOS for intelligent conversation routing.

Instead of dumping entire conversation histories into LLM context, DriftOS:

• Branches when new topics appear

• Stays when the topic continues

• Routes back when you return to a previous topic

DriftOS Backend

This MCP server requires a running DriftOS Core backend.

DriftOS Core is the semantic conversation routing engine that:

• Analyzes messages to detect topic shifts and returns

• Maintains a graph of conversation branches

• Extracts and tracks facts across topics

• Assembles relevant context for LLM calls

See the driftos-core repository for setup instructions.
