Ratatosk
Platform session runtime for the Willow fleet — the process that runs agent
turns on any node (desk, laptop, Termux phone) and speaks MCP to willow-mcp.
Role
Ratatosk is not memory (Nestor), not the desk (Grove). It is the session process: prompt → tools → loop, Grove lifecycle events, JSONL working set, tier-0 deposit sync.
Install
pip install "willow-ratatosk[mcp,cloud,local]"
# development
pip install -e ".[dev]"
Run
ratatosk --local
ratatosk --mcp
ratatosk --mcp --listen
ratatosk --mcp --deposit

willow-mcp registration
Ratatosk is a platform session identity, not a dispatch specialist. Install
its manifest under $WILLOW_HOME/mcp_apps/ratatosk/manifest.json (example in
docs/mcp-manifest.example.json). Without this, Grove tools deny with
app_id=ratatosk.
