Live crypto + energy predictive data + AI forecasts, right inside Claude (and any MCP-capable AI app).
This is a Model Context Protocol server that gives your AI assistant real-time predictive intelligence — Bitcoin network, mempool, and fees; Ethereum gas; best-time-to-transact timing on both chains; AI Bitcoin price forecasts; and Texas (ERCOT) electricity price forecasting including the cheapest upcoming window to run load — all as tools it can call mid-conversation. Data comes from the a0nexus.com Predictive Intelligence API.
Live Bitcoin fees/network/mempool, Ethereum gas, and current ERCOT power prices are free and need no wallet — install it and ask "what's the current Bitcoin fee?", "what's ETH gas right now?", or "what's Texas power costing?" right away. The differentiated tools (forecasts, fee forecast, confirmation ETA, mempool depth, intelligence brief) are pay-per-call: each request is settled with a few cents of USDC on Base via x402 (HTTP 402) — no account, no signup, no subscription. You only enable paid tools if you want them.
Install it with a single npx line (below). Node 18+ required.
| Tool | What it returns |
|---|---|
get_current_fees | Current recommended Bitcoin fee rates (sat/vB) by confirmation target. |
get_network_snapshot | Chain height, best block hash, peers, sync state, mempool summary. |
get_mempool_snapshot | Current mempool size, fee-rate histogram, and congestion. |
get_eth_gas_current | Ethereum gas now (gwei): base fee + slow/standard/fast tiers + congestion. |
get_ercot_price_current | Texas power now ($/MWh) on the ERCOT grid + cheap/normal/expensive level. Arg: hub. |
get_status | Service status, active payment mode, and component health. |
get_pricing | Per-endpoint pricing and the payment network in use. |
| Tool | What it returns |
|---|---|
get_broadcast_timing | Best time to broadcast (Bitcoin) — send now vs. wait, and the sat/vB you'd save. Args: target (blocks, default 6), vsize (vB, optional → total sats saved). |
get_eth_gas_timing | Best time to send (Ethereum) — send now vs. wait, and the gwei/ETH you'd save. Args: blocks (default 5), gas_limit (optional). |
get_eth_gas_forecast | Ethereum base-fee forecast (gwei), N blocks ahead. Args: blocks (default 5). |
get_ercot_cheapest_window | Cheapest window to run load (Texas grid) — when to charge/compute in the next 24h + savings vs the daily average. Args: window_hours (default 2), horizon_hours (default 24), hub. |
get_ercot_price_forecast | ERCOT electricity price forecast ($/MWh) for the next N hours. Args: hours (default 12), hub. |
get_fee_forecast | Forecast of Bitcoin transaction fees by confirmation target. |
get_tx_confirmation | Confirmation status / ETA for a transaction. Args: txid. |
get_latest_forecast | Latest published AI price forecast. Args: symbol (e.g. BTCUSD), timeframe (e.g. 1h, 4h, 1d). |
run_custom_forecast | Run a bespoke Kronos forecast. Args: symbol, timeframe, horizon, sample_count, lookback. |
get_intelligence | Aggregated Bitcoin intelligence brief. Optional arg: timeframe. |
Add the server to your AI app's MCP config. All three use the same one-line npx command — no clone, no build, no global install.
Edit claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json, Windows: %APPDATA%\Claude\claude_desktop_config.json):
{
"mcpServers": { "a0nexus-bitcoin": { "command": "npx", "args": ["-y", "a0nexus-bitcoin-mcp"], "env": { "BTCI_API_URL": "https://a0nexus.com" } } } }
Add an .mcp.json at your project root:
{
"mcpServers": { "a0nexus-bitcoin": { "command": "npx", "args": ["-y", "a0nexus-bitcoin-mcp"], "env": { "BTCI_API_URL": "https://a0nexus.com" } } } }
Edit ~/.cursor/mcp.json (global) or .cursor/mcp.json (per-project):
{
"mcpServers": { "a0nexus-bitcoin": { "command": "npx", "args": ["-y", "a0nexus-bitcoin-mcp"], "env": { "BTCI_API_URL": "https://a0nexus.com" } } } }
Restart the app. Your assistant can now fetch live Bitcoin fees and network status for free immediately — try asking *"what's the current Bitcoin fee?"*
The free tools work with no wallet at all. To unlock the paid tools, add two environment variables to the env block above:
"env": {
"BTCI_API_URL": "https://a0nexus.com", "BTCI_MCP_PAYMENT": "real", "BTCI_MCP_PRIVATE_KEY": "0x……" }
BTCI_MCP_PAYMENT: set to real to pay actual USDC. (Leave it unset, or none, for free-only operation.)BTCI_MCP_PRIVATE_KEY: the private key of a Base wallet holding a little USDC. Each paid call spends that endpoint's price (a few cents). Fund it with only what you're comfortable spending — call get_pricing to see exact per-endpoint costs.BTCI_MCP_NETWORK (optional): base (default) or base-sepolia for testnet.Treat the private key like any secret: use a dedicated low-balance wallet, and never commit it to source control.
Paid endpoints use the x402 standard: the server requests a resource, the API replies HTTP 402 Payment Required with a price, the client signs a USDC transfer on Base and retries, and the API returns live data. It's true pay-per-call metering — no account, no signup, no monthly bill. You pay only for the calls your assistant actually makes.
