BackPoW MCP server

• Registry namecom.backpow/pow-mining-oracleverified in the MCP registry

The registry name sits under backpow.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-21 the server answered initialize and tools/list without a sign-in. First answer in 93 ms.

• Whether its tools do the product's job has not been judged yet.
• Checked on 5 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

• Every tool passes all six checks.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• calculate_solo_mining_odds

  Probability of a solo miner finding a block, computed as a Poisson process over live network difficulty and hashrate, plus the electricity cost of the attempt. Returns mean time to a block, the chance of at least one block over…
