Zero Network MCP Server

Implementation Reference

• zero_mcp/server.py:573-576 (handler)

  The handler function for the `zero_transaction_format` tool, which returns the `TRANSACTION_FORMAT` string.

  @mcp.tool()
  def zero_transaction_format() -> str:
      """Get the Zero transaction wire format (136 bytes), account state format (48 bytes), and cryptographic primitives."""
      return TRANSACTION_FORMAT

• zero_mcp/server.py:60-93 (schema)

  The definition of the Zero transaction format, account state, and cryptographic primitives, which is returned by the tool.

  TRANSACTION_FORMAT = """# Zero Transaction Format (136 bytes)
  
  ```
  ZeroTransfer {
      from:      [32 bytes]  // Ed25519 public key (sender)
      to:        [32 bytes]  // Ed25519 public key (recipient)
      amount:    [4 bytes]   // u32, in units (1 unit = 0.01 Z = $0.0001)
      nonce:     [4 bytes]   // u32, per-account monotonic counter
      signature: [64 bytes]  // Ed25519 full signature
  }
  // Total: 136 bytes
  ```
  
  ## Amount Encoding
  - Amount is in units, not Z. 1 Z = 100 units.
  - To send 0.50 Z, set amount = 50
  - To send 1.00 Z, set amount = 100
  - Max amount: 2500 units (25 Z = $0.25)
  
  ## Account State (48 bytes per account)
  ```
  Account {
      balance:  [4 bytes]   // u32, current balance in units
      nonce:    [4 bytes]   // u32, last transaction nonce
      head:     [32 bytes]  // BLAKE3 hash of latest block
      flags:    [8 bytes]   // reserved (frozen, validator, etc.)
  }
  ```
  
  ## Cryptographic Primitives
  - Signatures: Ed25519 (ed25519-dalek with verify_strict)
  - Hashing: BLAKE3 (256-bit, hardware-accelerated)
  - Wire signature: Full 64-byte Ed25519 signature
