Cardano MCP Server

A Model Context Protocol (MCP) server for interacting with the Cardano blockchain from AI agents and automation systems.

This server exposes wallet-aware tools for:

• Submitting transactions
• Fetching addresses
• Reading UTxOs
• Fetching balances
• Resolving ADAHandles
• Checking stake delegation

Secrets

1. Copy the .env.example file to a new file .env
2. Specify your seed-phrase (SEED_PHRASE). Your seed-phrase is NEVER exposed to LLMs, and is only used for local wallet connection.
3. Configure the wallet connection details. Specify a Blockfrost Project ID (https://blockfrost.io/), or a Kupo & Ogmios URL.
