Built on the Model Context Protocol (MCP) for 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 12 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.

Tracking funds across multiple chains shouldn't require context switching., Solved with Vinkius AI Gateway

Today, tracking a single asset movement often means opening the Ethereum explorer, copying an address, going to the Polygon explorer, and repeating that process for every chain involved. You spend more time clicking tabs and formatting data than actually analyzing it.

With this MCP server, your agent handles all of it. Give it the source and destination addresses; it runs `get_address_summary` across multiple chains and returns a unified report. You stop managing interfaces and start drawing conclusions.

The OKLink Multi-chain Web3 Blockchain Data API MCP Server gives you full visibility.

Manual tracing requires pulling block data, then listing transactions for that block (`get_block_transactions`), and finally getting the detailed payload of each transaction using `get_transaction_detail`. It’s a three-step manual process with tons of copy/pasting.

Now, your agent manages the sequence. You ask it to trace funds, and it executes all those steps automatically in the background, returning one cohesive report. The complexity is abstracted away.

What your AI can actually do with this

This server connects your AI client directly to real-time blockchain data across dozens of networks, including Ethereum, Bitcoin, and BSC. It gives your agent the full ability to query structured on-chain intelligence without needing a manual explorer search.

To start, you'll use get_supported_chains to check exactly which blockchains we can access; that’s always good to know first. You can then grab general metadata about any supported network using get_chain_info.

Tracking Addresses and Accounts

If you need a quick read on an address, you've got two options: run get_address_summary for a high-level overview that gives you the current balance, total transactions count, and general activity metrics. For a deep dive, use get_address_transactions; this pulls a full, chronological list of every single transaction ever linked to that specific wallet or contract address.

Analyzing Tokens and Assets

The token tools let your agent investigate asset movements thoroughly. To see which tokens exist on a chain, you run get_token_list. You can then get detailed metrics—like the contract and full specs—for any type of token using get_token_detail. If you want to know how much of a specific token an address holds, you'll use get_token_balance.

For NFTs, if you know the collection contract, run get_nft_collection_info; this pulls all the metadata and details about that particular NFT set.

Inspecting Blocks and Transactions

When it comes to block data, your agent can check for the most recent activity by using get_latest_block on any supported chain. If you need granular specifics, running get_block_detail retrieves detailed information about a specific block hash, including its timestamp and who mined it. To see every transaction that made it into a block, use get_block_transactions, which gives you a list of all the associated transaction hashes.

Finally, if your agent finds a specific transaction hash, it can analyze the whole thing using get_transaction_detail. This function provides the full payload and status details for that single transaction, letting you see the gas cost, who sent it, and where it went. You'll also find that getting all historical or current transactions linked to an address is handled by get_address_transactions.

This suite of tools lets your AI client analyze everything from general wallet activity using get_address_summary, to tracing the full life cycle of a single token with get_token_balance, making it the definitive source for on-chain intelligence.

Questions you might have

How do I get a full history of an address using get_address_transactions? +

Calling get_address_transactions pulls all historical transaction hashes for that address. You can then pass those hashes into get_transaction_detail to see the payload and status of each one.

What is the difference between get_latest_block and get_block_detail? +

get_latest_block only retrieves the most recent block's metadata. Use get_block_detail when you already know a specific hash and need to inspect all its contents, like timestamps or miner details.

Can I check token balances for multiple networks with get_token_balance? +

You must specify the network context in your prompt. While get_supported_chains lists available networks, you need to run get_token_balance separately for each chain and token type.

Do I need get_nft_collection_info for every NFT asset? +

Yes, if you want collection metadata (like the contract or total supply), use get_nft_collection_info. This provides context beyond just checking the ownership record.

What credentials do I need to use the `get_address_summary` tool? +

You must provide your unique OKLink API Key when connecting the MCP Server. This key authorizes every single call, so make sure you store it securely within your client environment.

If I pass an invalid hash to `get_transaction_detail`, what error will my agent receive? +

The server returns a clear 'Not Found' status. This tells your AI client immediately that the specific transaction ID doesn't exist on any supported chain, saving you guesswork.

Are there rate limits when using the `get_token_list` tool across multiple chains? +

Yes, standard API rate limits apply. If your agent makes too many calls in quick succession, it will hit a 429 error. It's best to space out large batches of token lookups.

When I use `get_chain_info`, what core metadata can I retrieve about a blockchain? +

You get the chain’s name, native currency symbol, and total supply details. This helps your agent validate if the network is fully active or limited in scope.

How do I check the balance of a specific wallet address? +

You can use the get_address_summary tool by providing the chain name (e.g., 'eth') and the address. For a detailed list of all token holdings, use the get_token_balance tool.

Can I retrieve information about NFT collections? +

Yes! Use the get_nft_collection_info tool with the chain name and the NFT contract address to fetch metadata and collection details.

How do I find the latest block on a specific blockchain? +

Simply use the get_latest_block tool and specify the chain (e.g., 'btc', 'eth', 'polygon'). It will return the height and details of the most recently mined block.
