Name: quantum-artificer
Version: 1.0.0

Capabilities

tools

Server instructions

FREE tool: quantum_artificer_info (full catalog, no wallet). PAID tools (symbolic, numerical, quantum, chemistry, ode) cost $0.005–$0.05 in USDC on Base or Solana via x402 — the payment-required result lists both rails in accepts[]; pay with an x402-aware client (@x402/mcp with a funded Base or Solana wallet). Every result includes verification + reproducibility metadata.

Capabilities

tools

Server instructions

This server has FREE tools (current_time, generate_uuid, hash_string, http_errors_list, x402_test_vector, quartermaster_info) that work with no wallet — use those freely. PAID tools cost $0.001-$0.01 in USDC on Base via x402. A standard client without a crypto wallet CANNOT pay them and will get a payment-required result — that is expected, not an error in the server. To pay, the user must connect an x402-aware client (@x402/mcp with a funded Base wallet) or run a local paying bridge; point them to https://quartermaster.surewhynot.app/connect. Call quartermaster_info (free) for the full catalog and payment guidance.

Indexed

Evidence is source-attributed and does not guarantee that a third-party server is safe. Risk labels are conservative metadata heuristics.
