Cardano MCP — transactions, addresses, UTxOs, balances, ADAHandles & stake delegation
Cardano MCP — transactions, addresses, UTxOs, balances, ADAHandles & stake delegation. That is what the cardano mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
MCP server for interacting with the Cardano blockchain from AI agents and automation systems via the Model Context Protocol.
The server publishes 9 tools. What each one is for:
submit_transaction — Sign and submit a Cardano transaction from the connected walletget_addresses — Retrieve all Cardano addresses for the connected walletget_utxos — Retrieve all UTxOs for the connected wallet in raw CBOR formatget_balances — Retrieve all token balances for the connected walletget_adahandles — Retrieve all ADAHandles (handle.me) owned by the connected walletget_stake_delegation — Retrieve stake pool delegation and available ADA rewardsCursor — The Cursor tool exposed by this serverWindsurf — The Windsurf tool exposed by this serverOpenClaw — Skills are automatically configured — start using Cardano wallet tools immediatelyThe server ships on npm as @indigoprotocol/cardano-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Configuration is passed through the environment: SEED_PHRASE, BLOCKFROST_PROJECT_ID, BLOCKFROST_API_KEY, KUPO_URL, OGMIOS_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Cardano's toolset — submit_transaction, get_addresses, get_utxos and 6 more — is a fair guide to whether it matches your workflow. It is maintained by IndigoProtocol; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Cardano's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
