# agentsvc-mcp
**agentsvc.io MCP Server** — gives AI agents access to 20 pay-per-call utility services via the [x402 micropayment protocol](https://x402.org). Agents pay automatically in USDC on Base mainnet — no accounts, no API keys, no subscriptions.

## Installation
### Requirements
- Node.js 18+
- `npm install viem x402` (for payment signing)
- A wallet private key with USDC on Base mainnet
### Claude Desktop
```bash
curl -O https://agentsvc.io/mcp-server.mjs
npm install viem x402
```
Add to `claude_desktop_config.json`:
```json
{
"mcpServers": {
"agentsvc": {
"command": "node",
"args": ["/path/to/mcp-server.mjs"],
"env": {
"X402_PRIVATE_KEY": "0x..."
}
}
}
}
```
### Any MCP-compatible agent
The MCP server auto-discovers all 20 tools from the live catalog at startup. Tools are dynamically loaded — new services appear automatically without updating the server.
## How payments work
Each tool call uses the [x402 protocol](https://x402.org):
1. Agent calls a tool
2. Server probes the service (HTTP 402 response with payment requirements)
3. MCP server signs USDC payment on Base mainnet using your private key
4. Service executes and returns result
Payments are **atomic per call** — you only pay when a call succeeds. The wallet needs USDC on Base mainnet.
**Get USDC on Base:**
- Bridge from Ethereum: [bridge.base.org](https://bridge.base.org)
- Buy on Coinbase → withdraw to Base
- Swap on Uniswap/Aerodrome (Base)
## Cost examples
| Usage | Daily cost |
|-------|-----------|
| 100 calls/day (avg $0.003) | $0.30 |
| 1,000 calls/day | $3.00 |
| 10,000 calls/day | $30.00 |
## REST API
All tools are also available as a direct REST API without MCP:
```bash
# Step 1: probe (get payment requirements)
curl -X POST https://agentsvc.io/api/v1/proxy/ip-lookup \
-H "Content-Type: application/json" \
-d '{"ip": "8.8.8.8"}'
# → HTTP 402 with accepts[] payment requirements
# Step 2: sign + retry with X-Payment header
# See: https://agentsvc.io/docs
