Security Report

5.9

Moderate5.9Moderate Risk

poworacle is a keyless forwarding client that sends each tool call's arguments to the public BackPow MCP endpoint and returns the upstream content verbatim, which matches its stated purpose. No hardcoded secrets, shell execution, or filesystem access were found. The main concerns are low: third-party news content is passed unfiltered to the AI assistant, the endpoint override accepts non-HTTPS URLs, and the timeout does not cover reading the response body. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 2 high severity). Package verification found 1 issue.

poworacle

Live proof-of-work mining data as MCP tools: how long a solo miner would wait for a block, what it costs to produce one coin, the current state of a network, which hardware earns what, and recent mining news.

poworacle is a keyless forwarding client. It serves six tools over stdio MCP (and as CLI subcommands) and forwards each call to the public BackPow MCP endpoint at https://mcp.backpow.com/mcp — no API key, no account, nothing to configure. The upstream server is stateless, so each call is a single Streamable HTTP POST carrying a tools/call JSON-RPC request; the upstream result's content is returned verbatim. Upstream JSON-RPC errors come back as backpow error: <message>, an unparseable response as backpow error: malformed response, and a transport failure (including a timeout) as backpow unreachable.

Two environment variables adjust the client (both are this rebuild's own knobs, not upstream requirements):

Variable	Default	Purpose
`BACKPOW_MCP_URL`	`https://mcp.backpow.com/mcp`	Endpoint override
`BACKPOW_TIMEOUT_MS`	`30000`	Per-call timeout, AbortController-enforced

Tools

Tool	Answers
`calculate_solo_mining_odds`	Mean time to a block and Poisson odds over 1/7/30/90/365 days for a given coin and hashrate, plus the electricity cost of the attempt
`get_cost_of_production`	All-in electricity cost of mining one unit on the most efficient tracked hardware, against spot price and margin
`get_coin_oracle`	Live difficulty, hashrate, block height and reward for one chain, with a measurement-confidence block
`list_pow_coins`	Paginated catalogue of tracked PoW networks, filterable by algorithm or profitability
`get_hardware_benchmarks`	Hardware matched to the coins it can mine, ranked by net USD per day at a given electricity rate
`get_pow_news`	Recent PoW mining and network news, optionally filtered to one coin

Ambiguity and missing measurements are refused upstream rather than guessed or substituted, and those errors pass through unchanged apart from the backpow error: rendering.

CLI

npx @reneturcios/poworacle get_coin_oracle '{"coin_id":"Kaspa"}'
npx @reneturcios/poworacle calculate_solo_mining_odds '{"coin_id":"Bitcoin","hashrate":100,"hashrate_unit":"TH/s"}'
npx @reneturcios/poworacle list_pow_coins '{"algorithm":"SHA-256"}'
npx @reneturcios/poworacle --version

Each tool subcommand takes one JSON argument string. Exit codes: 0 on success, 1 when the tool result is an error, 2 on a usage error (unknown command, extra arguments, or a non-object JSON argument).

MCP

npx @reneturcios/poworacle mcp

MCP client configuration:

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

Docker

docker run -i ghcr.io/cloudcorprecords/poworacle          # stdio MCP server (CMD defaults to "mcp")
docker run --rm ghcr.io/cloudcorprecords/poworacle get_pow_news '{"coin_id":"Bitcoin"}'

Development

npm install
npm run build      # tsc -> dist/ (dist/cli.js is the bin)
npm test           # tsx --test test/*.test.ts (fake fetch only, no network)
npm run dev        # tsx src/cli.ts — run the CLI from source
