Cerebrus Pulse MCP

Cerebrus Pulse MCP

mcp-name: io.github.0xsl1m/cerebrus-pulse-mcp

MCP server for Cerebrus Pulse — real-time crypto intelligence for AI agents. Provides 15 tools covering technical analysis, liquidation heatmaps, market stress, funding rates, and more across 50+ Hyperliquid perpetuals.

Tools

Paid endpoints use x402 micropayments (USDC on Base or Solana). Free tools work without any configuration.

Prices are checked against the API's live x402 manifest (https://api.cerebruspulse.xyz/.well-known/x402) with python scripts/check_prices.py --live, which CI runs. The auto-pay payee pin is checked against a live 402 with python scripts/check_payto.py --live, which CI and the release workflow run.

Install

Claude Desktop / Cursor / Windsurf

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

{

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

To enable automatic x402 payments for paid endpoints, add a wallet key. The x402 client ships with the package, so the same uvx command pays; there is no extra to install:

{

"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.

Use a dedicated hot wallet that holds a few dollars of USDC on Base, never a main wallet: the key sits in plain text in the MCP config.

Auto-payment has spend limits, checked before anything is signed:

• no single payment above CEREBRUS_MAX_PAYMENT_USD (default 0.10; the priciest tool costs $0.06);
• no more than CEREBRUS_MAX_SPEND_USD in total while the server process runs (default 1.00; restart the server to reset it). The --json CLI starts a new process on every call, so this budget cannot span CLI calls, and the CLI does not auto-pay unless you opt in (see CLI Usage);
• only USDC on Base, and only to an address in CEREBRUS_ALLOWED_PAYTO (default: the published Cerebrus Pulse Base address), so a hijacked or mistyped CEREBRUS_BASE_URL cannot redirect payments.

A refused payment returns "status": "payment_blocked" with the reason; a malformed limit disables auto-payment rather than lifting the limit.

Without a wallet key, paid tools still work as discovery: they return the exact price, network, and recipient so the calling agent can pay however it likes.

pip

pip install cerebrus-pulse-mcp

CLI Usage

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

# List all available CLI tools

cerebrus-pulse-mcp --json

Free endpoints

cerebrus-pulse-mcp --json health cerebrus-pulse-mcp --json list-coins

Paid endpoints (return the payment terms unless CLI auto-pay is on, below)

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.

The CLI does not auto-pay by default, even with CEREBRUS_WALLET_KEY set. Every call is a new process with a fresh CEREBRUS_MAX_SPEND_USD budget, so the budget cannot stop a script that runs the CLI in a loop. Set CEREBRUS_CLI_AUTOPAY=1 to let it pay anyway: each call may then sign one payment of up to CEREBRUS_MAX_PAYMENT_USD, and limiting how many calls run is up to your script.

Configuration

Example Response
