Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Automate a task

Put BlockCypher to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

BlockCypher works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put BlockCypher to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 15 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of BlockCypher, so you can see the experience inside your AI.

It does not authenticate your account with BlockCypher. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work BlockCypher owners hand off.

This MCP is built for technical users who need to bridge the gap between natural language and blockchain protocols.

  • 01

    Web3 Developers

    They use the agent to check transaction statuses or generate testnet addresses without leaving their IDE.

  • 02

    Crypto Analysts

    They use the AI to audit wallet balances and inspect block data using text commands.

  • 03

    Fintech Teams

    They use the capability to automate blockchain monitoring and transaction broadcasting.

FAQ

Questions BlockCypher owners ask.

  • 01

    Which blockchains are supported?

    This MCP supports Bitcoin, Ethereum, Litecoin, and Dogecoin, along with various testnets.

  • 02

    Do I need my own BlockCypher API key?

    Yes, you will need to provide your BlockCypher API token to authenticate your requests.

  • 03

    Can I send transactions through my AI client?

    Yes, you can use the capability to create skeleton transactions, sign them, and broadcast them to the network.

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

  • 07

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

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

  • 08

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

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