Documentation

From the project's README on GitHub, refreshed weekly. Links open on GitHub.

Moved to peer-cli

Peer Cash MCP is now part of the canonical zkp2p/peer-cli runtime. This repository is archived and receives no fixes or releases.

Use the custody-separated Cash profile:

npx -y github:zkp2p/peer-cli#v0.1.0 mcp --profile cash

The tool names and custody boundary are preserved: peer_cash_* tools prepare unsigned transaction plans and never accept private keys, sign, or broadcast.

The published peer-cash-mcp npm package is historical. Do not start new integrations on it.
