Implementation Reference

• packages/mcp/src/tools/write.ts:30-75 (handler)

  The 't2000_send' tool is registered and implemented in 'packages/mcp/src/tools/write.ts'. It handles sending assets, supports dry runs for previews, and integrates with the agent's contacts and transaction enforcer.

  server.tool(
    't2000_send',
    'Send USDC or stablecoins to a Sui address or contact name. Amount is in dollars. Subject to per-transaction and daily send limits. Set dryRun: true to preview without signing.',
    {
      to: z.string().describe("Recipient Sui address (0x...) or contact name (e.g. 'Tom')"),
      amount: z.number().describe('Amount in dollars to send'),
      asset: z.string().optional().describe('Asset to send (default: USDC)'),
      dryRun: z.boolean().optional().describe('Preview without signing (default: false)'),
    },
    async ({ to, amount, asset, dryRun }) => {
      try {
        const resolved = agent.contacts.resolve(to);
  
        if (dryRun) {
          agent.enforcer.check({ operation: 'send', amount });
          const balance = await agent.balance();
          const config = agent.enforcer.getConfig();
