MCP server for interacting with the Cardano blockchain from AI agents and automation systems via the Model Context Protocol.
Part of the Indigo AI Stack β use alongside Indigo MCP for full Cardano DeFi capabilities.
That's it β 6 wallet tools configured for Claude Desktop, Claude Code, Cursor, or Windsurf.
Run the interactive setup to automatically configure your MCP client:
This will:
Install globally:
Or run directly with npx:
| Variable | Required | Description |
|---|---|---|
SEED_PHRASE | Yes | Your wallet seed phrase (comma-separated). Never exposed to LLMs. |
BLOCKFROST_PROJECT_ID | Yes* | Blockfrost API key from blockfrost.io |
KUPO_URL | Alt | Kupo endpoint URL (alternative to Blockfrost) |
OGMIOS_URL | Alt | Ogmios endpoint URL (alternative to Blockfrost) |
PORT | No | HTTP server port (default: 8000) |
*Either BLOCKFROST_PROJECT_ID or both KUPO_URL + OGMIOS_URL are required.
Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
Add to ~/.claude/settings.json or .claude/settings.json in your project:
Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project-level):
Add to ~/.codeium/windsurf/mcp_config.json:
Install Cardano skills for OpenClaw:
Skills are automatically configured β start using Cardano wallet tools immediately.
For full Cardano DeFi capabilities, use both Cardano MCP and Indigo MCP together:
| Tool | Description | Parameters |
|---|---|---|
submit_transaction | Sign and submit a Cardano transaction from the connected wallet | cbor: unsigned transaction CBOR hex string |
Output: { transactionHash: string, timestamp: number }
| Tool | Description | Parameters |
|---|---|---|
get_addresses | Retrieve all Cardano addresses for the connected wallet | None |
Output: { addresses: string[] }
| Tool | Description | Parameters |
|---|---|---|
get_utxos | Retrieve all UTxOs for the connected wallet in raw CBOR format | None |
Output: { utxos: string[] } (CBOR hex encoded)
| Tool | Description | Parameters |
|---|---|---|

Output:
| Tool | Description | Parameters |
|---|---|---|
get_adahandles | Retrieve all ADAHandles (handle.me) owned by the connected wallet | None |
Output: { adaHandles: string[] } (e.g., ["$myhandle", "$another"])
| Tool | Description | Parameters |
|---|---|---|
get_stake_delegation | Retrieve stake pool delegation and available ADA rewards | None |
Output:
Claude will use get_balances and respond with your ADA and token holdings.
Claude will use submit_transaction to sign and submit the CBOR transaction, returning the transaction hash.
Claude will use get_stake_delegation to show your staked pool and claimable rewards.
Claude will use get_adahandles to list all your handle.me handles.
If you use nvm and Claude Desktop shows "server disconnected", you need to use full paths since Claude Desktop doesn't inherit your shell's nvm setup:
Find your node path with: which npx
If tools fail after an update, clear the npm cache:
Then restart Claude Desktop.
