Frequently asked questions
How do I set up Cardano MCP?
Run `npx @indigoprotocol/cardano-mcp setup` for automatic configuration, or add environment variables to your MCP client’s JSON config file manually.
What environment variables are required?
`SEED_PHRASE` and `BLOCKFROST_PROJECT_ID` (or both `KUPO_URL` and `OGMIOS_URL` as alternative data providers). `PORT` is optional (default 8000).
Is my seed phrase exposed to LLMs?
No. The seed phrase is stored locally and used only by the local Lucid Evolution wallet instance. Transaction signing happens locally, and no private keys are transmitted.
Which clients are supported?
Claude Desktop, Claude Code, Cursor, Windsurf, and OpenClaw. Configuration examples for each are provided in the README.
