Nodeflare tools (21, 1 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • check_token_safety

    Risk-check an ERC-20 before trading it: metadata, contract + ownership status, upgradeable-proxy detection, holder concentration, and a transfer/honeypot simulation → risk signals + a score. The deep checks (concentration, honeypot) are heavy: needs NODEFLARE_API_KEY or X402_PRIVATE_KEY. Works on young chains (Zircuit, Robinhood, Plasma, Ink) that big indexers leave empty.

  • compare_gas

    Compare current gas price ACROSS chains in one call — gwei per chain, cheapest first, so an agent can pick where to transact. Defaults to the majors (eth, base, arb, op, bnb, polygon); pass chains to override.

  • eth_callwrite action

    Execute a read-only contract call (eth_call) and return the raw result.

  • get_balance

    Get the native-token balance of an address — raw wei plus a human-readable amount in the chain's native currency. The address may be an ENS name (e.g. 'vitalik.eth').

  • get_block

    Get a block by number or tag (e.g. 'latest', 'finalized', or a hex number). Set fullTransactions to include full tx objects instead of hashes.

  • get_block_number

    Get the latest block number on a chain (decimal and hex).

  • get_gas_price

    Get current gas pricing on a chain: base gas price and the suggested priority fee (EIP-1559), both in wei (hex).

  • get_logs

    Fetch contract event logs (eth_getLogs). Heavy method: needs NODEFLARE_API_KEY or an x402 wallet (X402_PRIVATE_KEY) — costs ~$0.001 via x402.

  • get_multichain_balances

    Get native + ERC-20 token balances for one address across many of the 23 EVM chains in a SINGLE call — including young chains (Robinhood, Plasma, Ink) that Alchemy/Moralis omit. With an x402 wallet (X402_PRIVATE_KEY) this is paid per request (~$0.0003/chain); otherwise it uses the free public tier.

  • get_token_allowances

    ERC-20 approvals a wallet has granted (what it approved and for how much) across many of the 23 EVM chains in ONE call — including young chains (Robinhood, Plasma, Ink) that revoke.cash-style tools skip. Scans Approval logs, reads the live allowance, drops revoked ones, flags unlimited approvals. Heavy: needs NODEFLARE_API_KEY or X402_PRIVATE_KEY.

  • get_token_balance

    Get an ERC-20 token balance for an address, returned both raw and human-readable (uses the token's decimals and symbol).

  • get_token_metadata

    Get ERC-20 token metadata: name, symbol, decimals and total supply (raw + human-readable).

  • get_token_price

    Current USD price of an ERC-20 token from DefiLlama (free, keyless): price + symbol + confidence, or null for unlisted/thin-market tokens. Well-covered chains only (eth, base, bnb, arb, op, avax, polygon, linea, mantle, sonic, unichain, sei, cronos).

  • get_transaction

    Get a transaction by its hash (from, to, value, input, block, gas).

  • get_transaction_receipt

    Get the receipt of a transaction by hash (status, logs, gas used).

  • get_wallet_report

    The full agent-ready 'know this wallet' report in ONE call: native + ERC-20 balances (USD-priced), a rolled-up total + top holdings, AND the active token approvals (revoke risk) across many of the 23 EVM chains — including young chains big indexers skip. The approvals half is heavy: needs NODEFLARE_API_KEY or X402_PRIVATE_KEY (balances/USD come back either way).

  • list_chains

    List the 23 EVM chains NodeFlare serves, with chain IDs and endpoint URLs.

  • onchain_answer

    Onchain Answer Engine: ask a plain-English question about any wallet or token across the 23 EVM chains and get back a CITED verdict in one call — 'is token 0x… on <chain> a scam?', 'what does wallet 0x… hold?'. NodeFlare plans the on-chain lookups, runs them on its own nodes, and synthesizes a sourced answer. Paid: needs NODEFLARE_API_KEY or X402_PRIVATE_KEY (no free anonymous tier — it runs on a

  • resolve_ens

    Resolve an ENS name to an address (forward), or a 0x-address to its primary ENS name (reverse). ENS is read from Ethereum mainnet.

  • rpc_call

    Make any JSON-RPC call on any supported chain. Heavy methods (eth_getLogs, trace_*, debug_*) need NODEFLARE_API_KEY or an x402 wallet.

  • simulate_transaction

    Transaction pre-flight on one chain: will this tx revert (and why), how much gas, and which tokens/ETH move? The asset-change tracing is heavy: needs NODEFLARE_API_KEY or X402_PRIVATE_KEY (revert/gas come back either way). Built for agents checking a tx before broadcasting.

Install Nodeflare in Claude Code, Cursor or VS Code

Runs npx -y nodeflare-mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Nodeflare repository's README, as published. We do not edit it. Read it on GitHub

NodeFlare MCP Server

Blockchain JSON-RPC for AI agents on 23 EVM chains — Ethereum, Base, BNB Chain, Arbitrum, Optimism, Avalanche, HyperEVM, Polygon, and young chains like Robinhood Chain, Plasma, Ink, Zircuit, BOB and Soneium. Served from NodeFlare's own bare-metal nodes across 5 regions.

Quick start

{
  "mcpServers": {
    "nodeflare": {
      "command": "npx",
      "args": ["-y", "nodeflare-mcp"]
    }
  }
}

That's it — no API key required for standard reads (block numbers, balances, transactions, eth_call).

Every tool's chain argument accepts a slug (eth, base, arb), a name (ethereum, arbitrum, bsc), or a numeric chain ID (1, 8453) — so agents don't have to know NodeFlare's internal slugs.

Install as a Claude Code plugin

This repo doubles as a Claude Code plugin marketplace. Installing the plugin wires up the MCP server and a set of slash-command recipes in one step:

claude plugin marketplace add Nodeflare-app/nodeflare-mcp
claude plugin install nodeflare

Then use the recipes below (/nodeflare:balance, /nodeflare:token, …). To unlock heavy methods, export NODEFLAREAPIKEY in your shell before starting Claude Code (free key, 2M CU/month).

Recipes

Ready-made slash commands bundled with the plugin:

Access tiers

The server picks its access tier from the environment:

With an x402 wallet, a blocked heavy method is retried automatically as a paid call — the tool result includes "_x402": "settled via x402" when a payment settled on-chain.

{
  "mcpServers": {
    "nodeflare": {
      "command": "npx",
      "args": ["-y", "nodeflare-mcp"],
      "env": { "X402_PRIVATE_KEY": "0x…" }
    }
  }
}

Use a dedicated agent wallet holding a small USDC balance — never your main wallet.
