# Mood Booster Agent

English | [中文](README_CN.md)

An ERC-8004 registered AI Agent that delivers uplifting messages via [MCP protocol](https://modelcontextprotocol.io/). Feel good? Tip 0.001 USDC!

## Why This Project?

This is a **complete reference implementation** of the ERC-8004 Agent interaction loop:

1. **On-chain Discovery** — Query Identity Registry to find the agent's MCP endpoint
2. **MCP Communication** — Connect via SSE, call tools, get results
3. **USDC Tipping** — Reward the agent with on-chain micropayments
4. **Reputation Feedback** — Submit on-chain feedback to Reputation Registry (`giveFeedback`)
5. **On-chain Verification** — Server verifies tips and feedback via tx receipts

All 5 steps leave traceable on-chain records on ERC-8004 protocol contracts, making your wallet eligible for future ecosystem airdrops.

## MCP Tools

| Tool | Description |
|------|-------------|
| `cheer_me_up` | Get a warm, uplifting message (encouragement / compliment / wisdom / joke) |
| `get_tip_info` | Get tipping details in JSON format for automated transfers |
| `confirm_tip` | Report a completed USDC tip with on-chain verification |
| `report_feedback` | Report an ERC-8004 giveFeedback transaction — leaves traceable protocol interaction on-chain |
| `how_to_tip` | Get a complete tipping guide with code examples |
| `get_stats` | View service statistics |

## Quick Start

### Run the server

```bash
cd server
npm install
node index.mjs
# MCP SSE: http://localhost:3004/sse
# REST API: http://localhost:3004/api/cheer
```

### Docker

```bash
docker build -t mood-booster-agent .
docker run -p 3004:3004 mood-booster-agent
```

### Full end-to-end loop

```bash
cd scripts && npm install

# Dry-run: discover → call MCP → on-chain feedback (no USDC tip)
node discover_and_tip.mjs --agent-id 23139 --chain bsc --wallet-key 0xYOUR_KEY --dry-run

# Full loop: discover → call → tip → confirm → feedback
node discover_and_tip.mjs --agent-id 23139 --chain bsc --wallet-key 0xYOUR_KEY

# Skip feedback
node discover_and_tip.mjs --agent-id 23139 --chain bsc --wallet-key 0xYOUR_KEY --no-feedback
```

### REST API (no MCP client needed)

```bash
curl https://oc-001.tail177fbd.ts.net/mcp/api/cheer
curl "https://oc-001.tail177fbd.ts.net/mcp/api/cheer?category=joke"
```

## Use with Claude Code

Add this to your `~/.claude/claude_code_config.json`:

```json
{
  "mcpServers": {
    "mood-booster": {
      "type": "sse",
      "url": "https://oc-001.tail177fbd.ts.net/mcp/sse"
    }
  }
}
```

Then in Claude Code you can say:

```
> Cheer me up!
> Tell me a programming joke
> How do I tip this agent?
```

## Use with Any MCP Client

```javascript
import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { SSEClientTransport } from "@modelcontextprotocol/sdk/client/sse.js";

const transport = new SSEClientTransport(new URL("https://oc-001.tail177fbd.ts.net/mcp/sse"));
const client = new Client({ name: "my-agent", version: "1.0.0" });

await client.connect(transport);
const result = await client.callTool({ name: "cheer_me_up", arguments: { category: "random" } });
console.log(result.content[0].text);
await client.close();
```

## On-Chain Discovery

Any agent can discover this service directly from the blockchain:

```javascript
import { ethers } from "ethers";

const registry = new ethers.Contract(
  "0x8004A169FB4a3325136EB29fA0ceB6D2e539a432",
  ["function tokenURI(uint256) view returns (string)"],
  new ethers.JsonRpcProvider("https://bsc-dataseed.binance.org/")
);

const uri = await registry.tokenURI(23139);  // agentId on BSC
const metadata = JSON.parse(atob(uri.split(",")[1]));
console.log(metadata.services[0].endpoint);  // → MCP endpoint URL
```
