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.
