Non-custodial crypto wallet MCP: check balances, sign and send transfers, and swap tokens locally.

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package @ironwallet/mcp-server
Claude Code
claude mcp add ironwallet -e 'IW_READ_ONLY=<IW_READ_ONLY>' -- npx -y @ironwallet/mcp-server@1.2.1
JSON configuration (Claude Desktop, Cursor, VS Code)
{
    "mcpServers": {
        "ironwallet": {
            "command": "npx",
            "args": [
                "-y",
                "@ironwallet/mcp-server@1.2.1"
            ],
            "env": {
                "IW_READ_ONLY": "<IW_READ_ONLY>"
            }
        }
    }
}

Environment variables

  • IW_READ_ONLY Set to true to disable send_transfer and execute_swap for the whole server. Balances, estimates, and lists still work.

IronWallet for AI agents

The IronWallet MCP server gives AI agents secure access to a non-custodial wallet. Seed phrases stay encrypted on the host and never leave this machine. Agents can retrieve balances, sign locally, transfer tokens, and swap across 10+ networks.

Seed-compatible with the IronWallet app. There is no per-transaction confirmation UI.

Requirements: Node.js 20+ (npx). Use a dedicated wallet with limited balance.

Product page: ironwallet.io/ai. Machine-readable index: llms.txt.

Opening this repository in Claude Code starts the wallet MCP via .mcp.json. See CLAUDE.md.

Install

Cursor: ironwallet.io/ai

Claude Code:

claude plugin marketplace add ironwallet/ironwallet-agent-kit
claude plugin install ironwallet-mcp@ironwallet

Codex:

codex plugin marketplace add ironwallet/ironwallet-agent-kit
codex plugin add ironwallet-mcp@ironwallet

Grok:

grok plugin marketplace add ironwallet/ironwallet-agent-kit
grok plugin install ironwallet-mcp --trust

Reload so MCP picks up PATH. From a local clone, use . instead of the GitHub repo.

MCP only (no plugin)

Manually installed MCP does not auto-update with the plugin.

No tool accepts or returns a seed. Import, backup, and delete only in the local browser (open_wallet_manager / backup_url); deleting asks the user to retype the wallet name.

Configuration

Nothing to paste into MCP config for normal use. On first launch the server writes a relay API key, keystore wrapping secret, device id, and installation id under ~/.ironwallet-mcp/ (mode 0600). Override with IW_RELAY_API_KEY / IW_PASSPHRASE / IW_DEVICE_ID only if you must.

The user-facing backup is the recovery phrase in the wallet manager, not those files.

Security

  • Seeds are encrypted at rest. They never appear in tool results, agent chat, or backend requests.
  • The agent can move funds without asking again. Optional wallet policy (readOnly, maxPerTxUsd, transfer recipient allow-list — set via set_wallet_policy) is off by default and applies to both sends and swaps.
  • Anyone with the keystore and the wrapping secret controls the funds. A leaked seed cannot be revoked.
  • Timeout is not always failure: poll status before retrying a send or swap.
  • Do not put a main wallet here. Use a small hot wallet.
