Works with Claude, ChatGPT, Cursor, and more

The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.

This connection provides 15 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.

Checking crypto balances used to be a click-and-copy nightmare.

Right now, if you need to know the total value of an address across Ethereum, Bitcoin, and Polygon, you're stuck. You copy the address, switch tabs, navigate to three different block explorer sites, run a search on each one, then manually aggregate the final numbers in a spreadsheet. It takes time, it’s prone to copy-paste errors, and it keeps you locked away from your actual work.

With this MCP, the process changes completely. You just tell your agent: 'What is the total balance of address X across BTC and ETH?' The system handles the multiple API calls in the background, pulling the latest data for every chain and giving you one consolidated answer. It's instant.

Generating new addresses with `generate_address`

Previously, generating a fresh keypair meant running separate CLI commands or using dedicated wallet services. You had to manage the process manually, ensuring you saved both the public address and the private key correctly.

Now, your agent handles it with one prompt. It generates a new keypair for supported coins and provides the necessary details directly in your chat window. The whole process is wrapped up cleanly.

What your AI can actually do with this

Need to look up asset flows across multiple major blockchains? This MCP connects your agent to real-time data feeds for Bitcoin, Ethereum, Litecoin, and several others. Instead of juggling separate block explorers and manual searches, you simply ask your AI client for the information you need—like checking a specific address's total balance or finding out which transactions happened in a given block height.

You can audit wallet histories instantly, retrieve detailed data about network activity, or even generate and send skeleton transactions right from your agent. When building complex tooling, Vinkius hosts this MCP, giving your AI client access to all these functions in one place. It's built for developers who need to treat blockchain interaction like a simple API call, letting you focus on the logic rather than the data retrieval.

Questions you might have

How do I check my current balance using get_address_balance? +

You pass the target wallet address to get_address_balance. It returns only the aggregated balance, which is useful when you don't need transaction history, just a quick number.

Can I broadcast transactions using send_transaction? +

Yes. After creating the skeleton with new_transaction and signing it, you use send_transaction. This sends the finalized data to the network for confirmation.

What is get_block_by_height used for? +

get_block_by_height lets you retrieve all details about a block based on its sequential number (height). This is ideal for analyzing time-based network activity.

What if I want to interact with an Ethereum contract? Do I use call_eth_contract_method? +

Yes, that's the right tool. You use call_eth_contract_method when you need your agent to execute a specific function on a smart contract address.

What information do I get from running `get_token_info`? +

This function confirms your API token's validity and scope. It tells you if the key is active, when it expires, and what permissions are attached to it. Always check this first to ensure your credentials haven't been revoked or reached a usage limit.

What steps should I follow when using `generate_address`? +

Running generate_address gives you a new public key and private keypair. Remember, the private key is critical; treat it like cash and store it offline immediately. The function ensures you start with a clean identity on the blockchain.

How does using `new_transaction` differ from sending data? +

new_transaction creates a skeleton transaction object for your agent to sign. You use this when you need to build the payload first, then pass it to send_transaction. This separation gives you control over the entire signing process.

What is the purpose of using `create_webhook`? +

create_webhook sets up automated notifications for specific events on a blockchain. Instead of constantly polling, your agent receives an alert when something happens—like a new block appearing or a transaction failing.

Can I check the balance of a specific address without fetching all its transaction history? +

Yes! Use the get_address_balance tool. It provides a lightweight response containing only the balance and basic metadata for the specified coin and chain.

How do I find the current block height and fee estimates for Bitcoin? +

Simply use the get_blockchain tool with 'btc' as the coin and 'main' as the chain. It will return the latest block height, hash, and current network fee tiers.

Is it possible to generate a new wallet address for testing purposes? +

Yes. The generate_address tool allows you to create a new public/private keypair and address for any supported chain (e.g., 'btc' on 'test3' or 'bcy' on 'test').
