+name: clicks-protocol
+description: Integrate autonomous USDC yield into AI agent projects on Base. Use when building agents that hold, earn, or transfer USDC, when asked about agent treasury management, DeFi yield for agents, x402 payment optimization, or idle USDC strategies.
+---
+
+# Clicks Protocol
+
+Add autonomous yield to any AI agent that holds USDC on Base. 80% stays liquid for operations, 20% earns variable yield via Aave V3 or Morpho. Non-custodial, no lockup, withdraw anytime.

+
+## Installation
+
+```bash
+npm install @clicks-protocol/sdk ethers@^6
+```
+
+## SDK Integration
+
+```typescript
+import { ClicksClient } from '@clicks-protocol/sdk';
+import { ethers } from 'ethers';
+
+const provider = new ethers.JsonRpcProvider('https://mainnet.base.org');
+const signer = new ethers.Wallet(process.env.AGENT_PRIVATE_KEY, provider);
+const clicks = new ClicksClient(signer);
+
+// Deposit 1000 USDC (register + approve + split in one call)
+const result = await clicks.quickStart('1000', signer.address);
+// Result: 800 USDC liquid, 200 USDC earning yield
+
+// Check balance
+const info = await clicks.getAgentInfo(signer.address);
+const balance = await clicks.getAgentYieldBalance(signer.address);
+
+// Withdraw anytime
+await clicks.withdrawYield(signer.address);
+```
+
+## Recurring Payments
+
+```typescript
+async function onPaymentReceived(amount: string) {
+  await clicks.receivePayment(amount, agentAddress);
+  // Automatically splits 80/20
+}
+```
+
+## SDK Methods
+
+| Method | Purpose |
+|--------|---------|
+| `quickStart(amount, agent, referrer?)` | Register + approve + deposit |
+| `receivePayment(amount, agent)` | Split incoming USDC 80/20 |
+| `withdrawYield(agent)` | Withdraw principal + yield |
+| `getAgentInfo(agent)` | Registration, deposits, yield pct |
+| `getAgentYieldBalance(agent)` | Current value and earned yield |
+| `getYieldInfo()` | Protocol APYs and totals |
+| `simulateSplit(amount, agent)` | Preview split |
+| `setOperatorYieldPct(pct)` | Adjust yield 5-50% |
+
+## MCP Server
+
+```bash
+npx @clicks-protocol/mcp-server
+```
+
+9 tools for read and write treasury operations. See `references/mcp-config.md`.
+
+## x402 Compatibility
+
+Clicks works with Coinbase x402 payments. 80% stays liquid for x402, 20% earns yield. Both on Base, no bridging.

+
+## Agent Referral System
+
+Agents refer other agents and earn from the protocol fee:
+
+```typescript
+await clicks.quickStart('1000', agentAddress, referrerAddress);
+```
+
+- L1: 40% of 2% fee | L2: 20% | L3: 10%
+- Team tiers: Bronze ($50k) to Diamond ($5M)
+
+## Security
+
+- Immutable contracts (no proxy, no admin upgrade)
+- ReentrancyGuard on all state-changing functions
+- 58/58 tests passing
+- Non-custodial, fee only on yield
