How to Use the Blockchain.com Data MCP in Cursor

Q: How do I add the Blockchain.com Data MCP Server to my Cursor project?

Create a .cursor/mcp.json file in your project root. Paste the server configuration with your Vinkius endpoint URL, and Cursor's Agent mode will immediately recognize the tools.

Q: Can Cursor automatically write tests using real Blockchain.com Data?

Yes. When you prompt the agent to write a test, it uses getblockcount or getlatestblock to fetch current network states and writes assertions against real live blocks.

Q: How do I pull historical price charts into my code?

Ask the editor to fetch market data. Cursor uses getchart to pull historical datasets, allowing you to quickly write visualization code using real numbers.

Feed live Bitcoin blockchain data directly into Cursor's Agent mode to write code with real-world context.

Build Web3 Apps in Cursor with Live Bitcoin Data

Stop writing code with mock JSON payloads. When you ask Cursor to build an address tracker, Agent mode uses `get_address` to pull real transaction history directly into your active file. By using this MCP Server, your editor writes functions against actual Bitcoin data structures. This means you catch parsing bugs before you even run your compiler.

Debug Transaction Logic with Real Hash Lookups

If your transaction processing code fails, ask Cursor to inspect the failure. The editor uses `get_transaction` and `get_block` to pull the exact raw transaction details into your chat. You can compare your local database states against the source of truth on the blockchain. This helps you identify confirmation delays or malformed inputs instantly.

Analyze Network Trends for Smart Fee Estimation

Write dynamic fee estimation logic by letting Cursor query live network congestion. The editor calls `get_mempool_stats` and `get_network_stats` to feed real-time demand metrics into your codebase. You can test your fee calculation algorithms against the actual unconfirmed transaction queue retrieved by `list_unconfirmed_transactions`.

Setup guide

Set up Blockchain.com Data MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Blockchain.com Data MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Blockchain.com Data transactions." If the MCP tools are loaded correctly, Cursor will call the Blockchain.com Data tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "blockchaincom-data-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
