Paid endpoints use [x402](https://x402.org/) micropayments (USDC on **Base** or **Solana**). Free tools work without any configuration.

## Install

### Claude Desktop / Cursor / Windsurf

Add to your MCP config (`claude_desktop_config.json`, `.cursor/mcp.json`, etc.):

```json
{
  "mcpServers": {
    "cerebrus-pulse": {
      "command": "uvx",
      "args": ["cerebrus-pulse-mcp"]
    }
  }
}
```

To enable automatic x402 payments for paid endpoints, install the payment
extra and add your wallet key:

```bash
pip install "cerebrus-pulse-mcp[pay]"
```

Then:

```json
{
  "mcpServers": {
    "cerebrus-pulse": {
      "command": "uvx",
      "args": ["cerebrus-pulse-mcp"],
      "env": {
        "CEREBRUS_WALLET_KEY": "your-base-wallet-private-key",
        "CEREBRUS_WALLET_KEY_SOLANA": "your-solana-wallet-private-key"
      }
    }
  }
}
```

Automatic payment currently covers **Base** only. `CEREBRUS_WALLET_KEY_SOLANA`
is reserved for a future Solana signer — the API accepts Solana today, but you
would need to settle those payments yourself.

Without a wallet key (or without the `[pay]` extra) paid tools still work as
discovery: they return the exact price, network, and recipient so the calling
agent can pay however it likes.

### pip

```bash
pip install cerebrus-pulse-mcp
```

## CLI Usage

The server includes a `--json` flag for direct CLI access without an MCP client:

```bash
# List all available CLI tools
cerebrus-pulse-mcp --json

# Free endpoints
cerebrus-pulse-mcp --json health
cerebrus-pulse-mcp --json list-coins

# Paid endpoints (returns payment details if wallet not configured)
cerebrus-pulse-mcp --json pulse BTC
cerebrus-pulse-mcp --json funding ETH lookback_hours=48
cerebrus-pulse-mcp --json screener top_n=10
cerebrus-pulse-mcp --json liquidations SOL
```

Arguments can be passed positionally (for coin) or as `key=value` pairs.

## Configuration

| Environment Variable | Description | Required |
|---------------------|-------------|----------|
| `CEREBRUS_BASE_URL` | API base URL (default: `https://api.cerebruspulse.xyz`) | No |
| `CEREBRUS_WALLET_KEY` | Base wallet private key for x402 auto-payment (requires the `[pay]` extra) | No |
| `CEREBRUS_WALLET_KEY_SOLANA` | Reserved; Solana auto-payment not yet implemented | No |

## Example Response

```bash
$ cerebrus-pulse-mcp --json health
{
  "status": "ok",

  "kill_switch": "enabled",
  "version": "1.2.0"
