Hive Ledger Bridge

srotzin/hive-mcp-ledger-bridge

Bridges hardware wallet signing into MCP by implementing the same EIP-712 intent envelope contract that shisad's ledger-bridge contrib module exposes. You get five tools: create an intent envelope with the typed data hash a Ledger device will sign, verify the hash matches, query which confirmation level an action requires (L0 through L4, verbatim from shisad's spec), attest that a signature reached L3 or L4, and look up the partner directory. Sits upstream of the USB bridge itself. Hive handles envelope construction and spectral receipt generation while shisad enforces per-call policy and Ledger does the on-device review. Useful if you're routing high-value intents through hardware countersignature and need the typed data layer without replacing your existing policy stack.

srotzin/hive-mcp-ledger-bridge MCP server

Hive Civilization — EIP-712 over USB/DMK ledger-bridge MCP server.

Implements the same signer-backend contract that shisa-ai/shisad exposes through contrib/ledger-bridge. Ledger is a partner. This server complements shisad — it does not replace it.
