OpenClawCash Agent Wallet (Claude Code plugin)

A crypto wallet for AI agents on Ethereum, Polygon, Base and Solana. Your agent gets an API key, never a private key, and every action is checked against the spending limits, allowlist and testnet-only rules you set before anything is signed. It can send, swap, bridge, trade on Polymarket and get paid through escrow. Backed by OpenClawCash.

The plugin connects Claude Code to the openclawcash MCP server (@openclawcash/mcp-server on npm) and bundles the agentwalletapi skill, so Claude follows the same safety model, approval flow, and wallet-label rules as every other OpenClawCash integration. Wallet keys and policy enforcement stay server-side.

Install

/plugin marketplace add openclawcash/agentwalletapi-claude-code
/plugin install agentwalletapi@openclawcash

Claude Code asks for your API key when you install (it is stored by Claude Code, not in the plugin). Change it later with claude plugin configure agentwalletapi@openclawcash.

Get a key at openclawcash.com (sign up, create a wallet, open API Keys).

Requirements

Required setting	agent_key, prompted at install (sensitive)
Optional env var	OPENCLAWCASH_BASE_URL (default https://openclawcash.com)
Runtime	Node.js with npx available

The key is only ever sent to https://openclawcash.com (or an https://<subdomain>.openclawcash.com host).

Two ways in, two key names

• The MCP tools get your key from the install prompt (agent_key) and pass it to the server as OPENCLAWCASH_AGENT_KEY. This is the normal path.
• The bundled skill's shell script (skills/agentwalletapi/scripts/agentwalletapi.sh) is a separate command-line path. It reads AGENTWALLETAPI_KEY from a .env file that skills/agentwalletapi/scripts/setup.sh creates next to it. You only need this if you call the script directly; the MCP tools work without it.

What you get

• The openclawcash MCP server: wallet, transfer, swap, bridge, approval, escrow checkout and Polymarket tools, all running through your wallet policies.
• The agentwalletapi skill — endpoint reference, safety model, and wallet-label rules; see skills/agentwalletapi/SKILL.md.
