Live Chain Context in Cursor Agent Mode

This Moonriver (Moonriver Block Explorer API) MCP Server feeds live network metadata and account balances directly to your editor using `get_account_info` and `get_metadata`. Your agent displays the actual chain states inside your active file. Instead of relying on hardcoded mock balances, your coding agent generates test suites using real-world numbers. You catch edge cases before committing your smart contract code.

Debug Smart Contracts with Real Extrinsics

Real-time debugging relies on `get_extrinsic` and `list_extrinsics` to inspect failed EVM executions. Your agent reads the exact transaction receipt to pinpoint where a call reverted. You can also pull lists of past events using `get_block` and `list_blocks`. This keeps your workspace updated with the latest finalized block hashes without switching to an external browser.

Map EVM Token Deployments

Tracking contract deployments is fast when using `list_evm_tokens` and `list_transfers`. The tool maps out token movements and identifies contract addresses on the fly. Cursor reads these payloads to auto-complete contract ABIs and token deployment scripts. You avoid manual verification steps and speed up your local development loop with this MCP tool.

Common questions about Moonriver (Moonriver Block Explorer API) MCP in Cursor

Add the server to your `.cursor/mcp.json` file in your project root or global directory. Once configured, enable Agent mode in the chat panel to let the editor access the tools.

Yes, you can add a remote URL directly to your configuration file. This allows your team to share a single hosted endpoint instead of running local instances.

No, this specific toolset is dedicated exclusively to the Moonriver network. It queries the Moonriver block explorer API and cannot fetch data from unrelated networks.

The tools will return an error message to your chat window. You can write fallback logic in your scripts, but the MCP server itself requires a stable connection to the explorer API.

No, your queried blockchain addresses and transaction hashes are transmitted directly between your local editor and the Moonriver API. No intermediary database stores your queries, ensuring your development environment remains secure.
