Install Shift in Claude Code, Cursor or VS Code
Runs npx -y @cyanheads/shift-mcp-server on your machine. Read the scan report first; the gateway never runs local packages.

@cyanheads/shift-mcp-server Lightweight coordination layer for multiple AI agents working on the same codebase simultaneously. 2 Tools • 1 Resource
Overview
Coordination layer for multiple AI agents working on the same codebase at once. Check in with a gist of your task and the files you expect to touch, see the full roster of active peers, and check out when finished — all from any MCP client. Runs as a stdio process or a local Streamable HTTP server.
Tools
Resources
The same roster is returned inline by shiftcheckin; subscribers to shift://status also receive notifications/resources/updated on every check-in, session update, and check-out.
Capability reference
shiftcheckin tool
- Required gist (what you're working on) plus optional files you expect to modify
- Optional workerId (6-char uppercase alphanumeric) re-enters an existing session with patch semantics — omitted fields and the original checkedInAt are preserved
- Output carries your session plus activeWorkers, the full roster of every checked-in session
- An unrecognized workerId fails with typed reason unknown_worker (NotFound) — recovery: omit workerId to start fresh, or reuse an ID from the active-workers table embedded in the error
- Every check-in or update calls notifyResourceUpdated('shift://status')
shiftcheckout tool
- Required workerId (6-char uppercase alphanumeric), optional one-sentence summary
- Idempotent — an unknown or already-checked-out workerId succeeds silently rather than erroring
- Notifies shift://status subscribers only when a session actually existed and was removed
