Perplexity

Direct Chain Queries in Claude Desktop

This Moonriver (Moonriver Block Explorer API) MCP Server connects your local workspace to the Moonriver network using `get_account_info` and `get_metadata`. You run live queries to pull real-time balances and runtime structures directly into your chat. Stop copying and pasting transaction hashes from web explorers. Your local agent reads the exact network state, letting you analyze account nonces or chain metadata instantly.

Inspect Blocks and Extrinsics

We expose block details and transaction histories using `get_block`, `list_blocks`, and `get_extrinsic`. Your agent parses raw block data to verify finality or investigate specific transaction failures without manual searching. If you need to trace a series of transactions, the `list_extrinsics` tool pulls the batch directly into your workspace. Claude Desktop formats the raw hex into readable JSON so you can diagnose execution issues on the spot.

Track EVM Tokens and Transfers

Token tracking becomes straightforward with `list_evm_tokens` and `list_transfers`. Your agent pulls active token lists and monitors transfer events for any specified address. This setup bypasses third-party portfolio frontends. You get the raw, unedited transfer logs straight from the Moonriver ledger to verify ERC-20 movements in real time using our MCP tools.

Common questions about Moonriver (Moonriver Block Explorer API) MCP in Claude Desktop

Yes, you can configure remote connection strings in your settings. This lets you access live blockchain queries without running the server process on your local machine.
