Common questions

Is BackPow PoW Oracle safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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:

In ChatGPT, go to Explore GPTs → + Create (or configure an existing GPT).
Under Configure, scroll down to Actions → Create new action.
Click Import from URL and paste:

   https://mcp.backpow.com/openapi.json

Click Import. All 6 tools will populate automatically with zero authentication required.

Settings → Connectors → Add custom connector → https://mcp.backpow.com/mcp

VS Code

Cursor

Settings → MCP → Add, or in ~/.cursor/mcp.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:

"mcpServers": { "backpow": { "command": "npx", "args": ["-y", "@backpow/mcp-server"] } } }

Tools

Tool	Answers
`calculate_solo_mining_odds`	"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
`get_cost_of_production`	"Is mining Monero profitable?" — CoP vs spot, gross margin, the reference machine and tariff, 30-day trend
`get_coin_oracle`	"What is Kaspa's current difficulty?" — live network state with a confidence block
`list_pow_coins`	Browse or filter the tracked networks by algorithm or profitability
`get_hardware_benchmarks`	"What should I mine with an RTX 4090 at 0.10 USD/kWh?" — coins ranked by net USD/day
`get_pow_news`	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:

"warnings": [ /* plain prose caveats that qualify how the figures should be read */ ], "source": { "as_of_utc": "2026-09-18T08:12:00Z", "data_age_seconds": 30, "served_from": "live", "url": "https://backpow.com/Bitcoin", "cite_as": "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.

Two deliberate behaviours worth knowing:

Ambiguity is refused, not guessed. Several tickers are shared by multiple tracked chains (DGB by 5, XVG by 5). get_coin_oracle {"coin_id": "DGB"} returns an error listing the candidates rather than picking one, so an answer is never about a different network than the caller meant.
An unavailable measurement is refused, not substituted. When a network's current state cannot be measured, the tool returns an error rather than a placeholder such as 0 H/s, which a caller could not tell apart from a real reading.

Data and licence

Figures derive from BackPow's stratum collector nodes and market data, and are published under CC BY 4.0 — see backpow.com/llms.txt. Citation is requested, permission is not required.

This is a calculator and data source, not financial advice. No tool executes a transaction.

Development

Node 22 or newer is required: the Cloudflare Workers toolchain needs it. The published package itself runs on Node 20 and above.

npm install

npm run typecheck # tsc --noEmit npm test # unit + integration, no network npm run dev # wrangler dev on :8787 npm run conformance -- http://127.0.0.1:8787 # protocol probe against a running server npm run deploy # Cloudflare Workers

scripts/conformance.mjs drives a live endpoint through the transport and security behaviours that only show up over a real HTTP connection: status codes, header negotiation, origin checks and protocol-version handling. Point it at a local wrangler dev instance, or at the deployed endpoint.

Transport

Streamable HTTP on a single endpoint, POST /mcp. The server is stateless: it mints no session ids, GET and DELETE answer 405, and notifications get 202 with no body. Protocol revisions 2025-11-25 through 2024-11-05 are negotiated at initialize; server/discover reports the supported set.

/sse and /message, the paths of the deprecated HTTP+SSE transport, answer 410 pointing at /mcp.
