@adamik/signer-mcp-server v1.0.1

Adamik Signer MCP Server

This is an MCP (Model Context Protocol) server that provides digital signature capabilities for blockchain transactions. It is designed to work in tandem with the adamik-mcp-server, which handles transaction encoding and state introspection. This signer server provides a secure interface to sign transactions after confirming user intent.

🚀 Features

• 🔐 Single Wallet Session: Only one wallet can be connected per session to avoid ambiguity in signature requests.
• 🔎 Introspect Wallet State: Check whether a wallet is connected and what types of signers are available.
• 🔑 Key Derivation: Derive public keys from a given signer specification.
• ✍️ Transaction Signing: Sign encoded payloads in accordance with the Adamik protocol.
• 📖 Usage Guidance: The readMeFirst tool helps orient LLMs or developers before invoking sensitive actions.
