Ask which client you're using (Claude Desktop, Claude Code, Cursor, Windsurf)\n2. Prompt for your Blockfrost Project ID\n3. Prompt for your wallet seed phrase (stored locally, never exposed to LLMs)\n4. Automatically update your config file\n\n### Manual Installation\n\nInstall globally:\n\n```bash\nnpm install -g @indigoprotocol/cardano-mcp\n```\n\nOr run directly with npx:\n\n```bash\nnpx @indigoprotocol/cardano-mcp\n```\n\n### Docker\n\n```bash\ndocker build -t cardano-mcp .\ndocker run -p 8000:8000 \\\n  -e PORT=8000 \\\n  -e SEED_PHRASE=\"your seed phrase here\" \\\n  -e BLOCKFROST_PROJECT_ID=\"your_blockfrost_key\" \\\n  cardano-mcp\n```\n\n## Configuration\n\n### Environment Variables\n\n| Variable | Required | Description |\n|----------|----------|-------------|\n| `SEED_PHRASE` | Yes | Your wallet seed phrase (comma-separated). Never exposed to LLMs. |\n| `BLOCKFROST_PROJECT_ID` | Yes* | Blockfrost API key from [blockfrost.io](https://blockfrost.io/) |\n| `KUPO_URL` | Alt | Kupo endpoint URL (alternative to Blockfrost) |\n| `OGMIOS_URL` | Alt | Ogmios endpoint URL (alternative to Blockfrost) |\n| `PORT` | No | HTTP server port (default: 8000) |\n\n*Either `BLOCKFROST_PROJECT_ID` or both `KUPO_URL` + `OGMIOS_URL` are required.\n\n### Claude Desktop\n\nAdd to `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS) or `%APPDATA%\\Claude\\claude_desktop_config.json` (Windows):\n\n```json\n{\n

Combined with Indigo MCP\n\nFor full Cardano DeFi capabilities, use both Cardano MCP and [Indigo MCP](https://github.com/IndigoProtocol/indigo-mcp) together:\n\n```json\n{\n  \"mcpServers\": {\n    \"indigo\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"@indigoprotocol/indigo-mcp\"],\n      \"env\": {\n        \"BLOCKFROST_API_KEY\": \"your-blockfrost-project-id\"\n      }\n    },\n    \"cardano\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"@indigoprotocol/cardano-mcp\"],\n      \"env\": {\n        \"SEED_PHRASE\": \"word1,word2,word3,...\",\n        \"BLOCKFROST_PROJECT_ID\": \"your-blockfrost-project-id\"\n      }\n    }\n  }\n}\n```\n\n## Available Tools\n\n### Transaction Tools\n\n| Tool | Description | Parameters |\n|------|-------------|------------|\n| `submit_transaction` | Sign and submit a Cardano transaction from the connected wallet | `cbor`: unsigned transaction CBOR hex string |\n\n**Output:** `{ transactionHash: string, timestamp: number }`\n\n### Address Tools\n\n| Tool | Description | Parameters |\n|------|-------------|------------|\n| `get_addresses` | Retrieve all Cardano addresses for

ADA and token holdings.\n\n### Submit a Transaction\n\n```\n\"Submit this transaction: 84a400...\"\n```\n\nClaude will use `submit_transaction` to sign and submit the CBOR transaction, returning the transaction hash.\n\n### Check Staking Rewards\n\n```\n\"How much staking rewards do I have available?\"\n```\n\nClaude will use `get_stake_delegation` to show your staked pool and claimable rewards.\n\n### Resolve ADAHandles\n\n```\n\"What ADAHandles do I own?\"\n```\n\nClaude will use `get_adahandles` to list all your handle.me handles.\n\n## Troubleshooting\n\n### nvm Users (macOS/Linux)\n\nIf 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:\n\n```json\n{\n  \"mcpServers\": {\n    \"cardano\": {\n      \"command\": \"/Users/YOU/.nvm/versions/node/v22.x.x/bin/npx\",\n      \"args\": [\"-y\", \"@indigoprotocol/cardano-mcp\"],\n      \"env\": {\n

}\n  }\n}\n```\n\nFind your node path with: `which npx`\n\n### Cache Issues\n\nIf tools fail after an update, clear the npm cache:\n\n```bash\nrm -rf ~/.npm/_npx\n```\n\nThen restart Claude Desktop.\n\n## Platform Support\n\n| Platform | Status | Notes |\n|----------|--------|-------|\n| macOS | ✅ Full support | Intel & Apple Silicon |\n| Windows | ✅ Full support | Windows 10/11 |\n|
