Source code Documentation

What can you do with io.github.shemshallah/qtcl-mcp-server?

  • Agent-to-agent micropayments for API calls, compute, and data
  • Escrow for multi-agent task coordination (agent A pays agent B on task completion)
  • Autonomous treasury management with deterministic fee budgeting
  • Verifiable payment receipts via transaction hash + memo field
  • Cross-agent accounting with structured memo data
  • Quantum-secured key management for high-value operations
  • Decentralized agent identity anchored to QTCL addresses

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Why agents use QTCL

Flat 1-qsat fee — No gas estimation, no auctions, no MEV. Agents budget deterministically.

Fast settlement — ~18 second blocks. Submit → hash returned immediately. 1 confirmation = finality.

Post-quantum security — HypΓ cryptography (Schnorr-Γ over PSL(2,R)). Transactions are unforgeable even by quantum computers. No migration timeline to worry about.

Machine-native API — Pure JSON-RPC. One HTTP POST to transact. No Web3 libraries, no ABI encoding.

Memo field — Every transaction carries 256 chars for invoice IDs, service references, or structured agent-to-agent coordination data.

No approval pattern — No ERC-20 approve/transferFrom. Direct transfers. One call, one transaction.

Quantum infrastructure

  • Oracle network: 5-oracle Byzantine consensus (3-of-5 majority voting)
  • W-state: Tripartite entanglement with NPT witness
  • QRNG: 5-source ensemble (ANU, Random.org, QBICK, HotBits, Fourmilab)
  • Tessellation: {8,3} hyperbolic Poincaré disk, depth 5, 10,920 triangles
  • Consensus: Proof of Coherence (PoC) with non-Markovian memory kernel
