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

Reading block explorers requires endless tab switching., Solved with Vinkius AI Gateway

Today, if you need to verify a transaction's impact, you open the Moonriver explorer. You copy the hash, paste it into one tab for details, then open another tab to check the surrounding blocks, and maybe a third just to list all tokens involved. You spend more time clicking than analyzing.

With this MCP server, your agent handles the entire flow. Just ask: 'What happened with transaction X?' The AI client automatically calls `get_extrinsic` and cross-references it against `list_evm_tokens`, delivering one clean summary directly to you.

The Moonriver Block Explorer API MCP Server makes querying data simple.

Previously, fetching an account's full history meant manually running multiple queries: first listing blocks via `list_blocks`, then finding all the associated transactions using `list_extrinsics`, and finally aggregating those details with `get_account_info`. It was a multi-step coding chore.

Now, you just ask your agent to 'Check the full activity for this address.' The server orchestrates the calls—running `list_transfers` and pulling current balance data via `get_account_info`—and gives you a unified report. That's how it should work.

What your AI can actually do with this

This API lets your AI agent query deep on-chain data points across the entire Moonriver network. You can check account balances, track token movements, and analyze transaction history directly from your chat or IDE without leaving your current window.

When you use get_metadata, your agent pulls high-level status information about the whole Moonriver network. This gives you a quick snapshot of what's going on across the chain. You can also get a list of all available ERC-20 and ERC-721 token contracts using list_evm_tokens. That function returns a complete roster, so you know exactly which assets are running on Moonriver.

For tracking wallets, you've got two key tools. First, run get_account_info to nail down a specific account address. This gives you the current balance, general metadata, and all the core details for that wallet. You can then use list_transfers to get a chronological list of every fund movement associated with that same account; it's your full transfer history.

To understand what's happening at the block level, start by running list_blocks. This returns a list of recent blocks on the chain, giving you both the height and the timestamp for each one. If you need the whole scoop on just one block—say, Block 12345—you use get_block, which retrieves all the complete details for that specific ID or height.

When it comes to transactions, you've got granular options. You can run list_extrinsics to get a summarized list of recent transaction records, either for a specified address or within a given time period. If you want every single data point on one particular transfer—the full details of an extrinsic—you use get_extrinsic by providing its hash or index.

These tools let you see the raw mechanics of how funds move across Moonriver.

Basically, your agent handles all this complex querying for you: it collects a list of recent blocks via list_blocks, gets the full details of any single block using get_block, and monitors every fund movement through list_transfers while also keeping track of balances with get_account_info. You'll never have to jump between dashboards or manually format these queries again.

It just works.

Questions you might have

What is the difference between using `list_extrinsics` and `list_transfers`? +

List_extrinsics gives a summary list of raw transactions by hash or time. Use it when you need to see what was sent. List_transfers, on the other hand, provides a cleaner history focused specifically on fund movement and account balances.

How do I get information about all available tokens using `list_evm_tokens`? +

list_evm_tokens returns a list of contracts (ERC-20, ERC-721). This is your starting point for any token audit. You then use the contract addresses returned to check specific transfers with get_account_info.

What information does `get_block` provide? +

get_block gives you all the raw data associated with a single block height, including its timestamp, collator, and every transaction that was included in it. It’s the deepest dive into a specific moment on the chain.

Can I use `get_metadata` to check network health? +

Yes, get_metadata pulls high-level information about the Moonriver network itself—things like its current version or status. It gives you context that isn't tied to a specific account or block.

Should I use `list_blocks` first when tracking transactions? +

It depends on your goal. If you want the latest activity, start with list_blocks. This gives you the current range of blocks, which helps narrow down where to look for recent transactions using list_extrinsics.

What credentials are required to run `get_account_info`? +

You must provide your Moonriver API key in the request headers. This ensures secure access, preventing unauthorized queries and keeping network data private.

If I try to run `get_block` with an invalid height, what error should I expect? +

The server returns a specific API error code (like 404). Your AI client must check this status code before attempting to parse any block data.

When using `list_transfers`, how can I optimize fetching history across many addresses? +

You should paginate your requests by utilizing start and end parameters. This prevents hitting rate limits and keeps the massive transfer dataset manageable for processing.

Can I check the balance and metadata of a specific Moonriver address? +

Yes! Use the get_account_info tool by providing the wallet address. Your agent will return the current balance and associated account metadata.

How can I track token transfers for a specific user? +

Use the list_transfers tool with the user's address. It will retrieve the history of token transfers (ERC-20/ERC-721) for that specific account.

Is it possible to look up a transaction using its hash? +

Absolutely. Use the get_extrinsic tool and provide the transaction hash to get full details about that specific operation on the network.
