How to Use the BlockCypher (Multi-chain Blockchain Developer API) MCP in Cursor

Q: How do I add BlockCypher (Multi-chain Blockchain Developer API) to my Cursor workspace?

Create a .cursor/mcp.json file in your project root and add the BlockCypher MCP server configuration. Once saved, the Cursor agent will automatically detect the new tools and use them during code generation.

Q: Can Cursor use BlockCypher (Multi-chain Blockchain Developer API) to sign transactions locally?

Yes. The agent uses newtransaction to build the unsigned transaction skeleton, which you can then sign locally using your own scripts before broadcasting it.

Q: Does the BlockCypher (Multi-chain Blockchain Developer API) integration with Cursor support local testnets?

It supports the BlockCypher test chains via fundbcytestaddress and fundbethtestaddress. For local Ganache or Hardhat nodes, you should use a dedicated local network toolset instead.

Q: How do I configure webhook notifications using this tool?

You can ask the Cursor agent to call createwebhook with your target URL and transaction event types. The server registers the hook with BlockCypher, and you will start receiving payload alerts at your endpoint.

Build, test, and deploy multi-chain smart contracts inside Cursor using the BlockCypher MCP Server.

Perplexity

Direct blockchain debugging inside the Cursor agent

The BlockCypher MCP Server feeds real-time blockchain telemetry directly into your Cursor editor sessions. When your agent writes code, it calls `get_blockchain` and `get_block_by_height` to pull live network state instead of relying on outdated mocks. If your code fails during a transaction test, the agent uses `get_transaction` to inspect the exact failure reason on-chain. You see the raw transaction details immediately in your active sidebar chat without leaving your workspace.

Generate and fund test addresses on the fly

The BlockCypher address generation toolset lets Cursor generate valid cryptographic keypairs and fund them instantly as you write your scripts. Your editor agent calls `generate_address` to create new credentials and immediately writes them to your local environment file. To run integration tests, the agent executes `fund_bcy_test_address` or `fund_beth_test_address` to load testnets with gas. You get a fully loaded test account ready for deployment in seconds, completely automated by your editor.

Deploy and execute smart contracts from the editor

This MCP integration allows Cursor to deploy Ethereum contracts and call their methods directly from your workspace. The agent uses `create_eth_contract` to push your compiled bytecode to the network and tracks the deployment status. Once deployed, your agent tests the contract live by invoking `call_eth_contract_method` with specific parameters. You verify contract behavior against live state without running manual scripts or external CLI tools.

Setup guide

Set up BlockCypher (Multi-chain Blockchain Developer API) 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 BlockCypher (Multi-chain Blockchain Developer API) 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 BlockCypher (Multi-chain Blockchain Developer API) transactions." If the MCP tools are loaded correctly, Cursor will call the BlockCypher (Multi-chain Blockchain Developer API) tools automatically. You can also check Settings → MCP for a green status indicator.
