BackpowCom/backpow-mcp-server

The official Model Context Protocol server for
BackPow — The Proof of Work Oracle.
It gives an AI assistant live mining data for 126+ Proof of Work networks and 770+
hardware models: network difficulty and hashrate, Poisson solo-mining
probabilities, Cost of Production, and hardware profitability.
Remote endpoint: https://mcp.backpow.com/mcp — Streamable HTTP, no API key,
no account.
Local package: @backpow/mcp-server — the same six tools over stdio.
## Install
### ChatGPT (Custom GPTs & Actions)
Connect BackPow's live PoW data directly to your ChatGPT:
1. In ChatGPT, go to Explore GPTs → + Create (or configure an existing GPT).
2. Under Configure, scroll down to Actions → Create new action.
3. Click Import from URL and paste:
text
https://mcp.backpow.com/openapi.json
4. Click Import. All 6 tools will populate automatically with zero authentication required.

"servers": {
"backpow": { "type": "http", "url": "https://mcp.backpow.com/mcp" }
### Cursor
Settings → MCP → Add, or in ~/.cursor/mcp.json:
json
"mcpServers": {
"backpow": { "url": "https://mcp.backpow.com/mcp" }
### Local stdio
For clients that run a local process instead of calling a URL. It talks to the
same public endpoints as the remote server, so it needs no key either:
json
"mcpServers": {
"backpow": { "command": "npx", "args": ["-y", "@backpow/mcp-server"] }
## Tools
| Tool | Answers |
| calculatesolominingodds | "How long to solo mine a Bitcoin block at 100 TH/s?" — mean time, Poisson probability over 1/7/30/90/365 days, the luck spread, and what the electricity costs while you wait |
| getcostofproduction | "Is mining Monero profitable?" — CoP vs spot, gross margin, the reference machine and tariff, 30-day trend |
| getcoinoracle | "What is Kaspa's current difficulty?" — live network state with a confidence block |
| listpowcoins | Browse or filter the tracked networks by algorithm or profitability |
| gethardwarebenchmarks | "What should I mine with an RTX 4090 at 0.10 USD/kWh?" — coins ranked by net USD/day |
| getpownews | Recent mining and network events, quoted as third-party content |
All six are read-only and annotated readOnlyHint, so hosts that support
auto-approval will not prompt on every call.
## How results are shaped
Every successful result is an envelope:
jsonc
"warnings": [ / plain prose caveats that qualify how the figures should be read / ],
"source": {
"asofutc": "2026-09-18T08:12:00Z",
"dataageseconds": 30,
"servedfrom": "live",
"url": "https://backpow.com/Bitcoin",
"citeas": "BackPow — The Proof of Work Oracle, \"BTC solo mining odds\", retrieved 2026-09-18 — https://backpow.com/Bitcoin",
"methodology": "…"
},
"data": { / the figures / }
Difficulty, hashrate and price move continuously, so a figure only means
something alongside the moment it was measured. Every result therefore carries
its measurement timestamp and a ready-made citation line.
