What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

list_chains
List every chain MoltNode serves (slug, name, chainId, family, native coin, endpoint) and which ones Chord trades on. Call this first for valid chain slugs.
rpc_call
Call any JSON-RPC 2.0 method on a chain through MoltNode, no API key. EVM chains use eth_* methods; Solana and Sui use their own.
get_block_number
The latest block number of an EVM chain, as a decimal integer.
get_balance
The native-coin balance of an address on an EVM chain, in wei and in whole coins.
chord_find_token
Find a token by symbol, name or address on a chain Chord trades on (base, ethereum, monad, bnb, avalanche, arbitrum, robinhood, arc). Returns addresses, decimals and whether the token is verified; similar tickers are common, so compare addresses.
chord_swap_quote
Best swap route from Chord (getchord.xyz) across the DEXs of the chain, with the UNSIGNED transaction to sign, the ERC-20 approval it needs (as a ready transaction) and a simulation run from the taker wallet. Amounts are integer strings in the token's smallest unit; the zero addr
send_raw_transaction
Broadcast a signed transaction (0x-prefixed raw bytes) on an EVM chain through MoltNode. Returns the transaction hash and an explorer link.

Common questions

Is MoltNode by Chord safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.4) reached the registry 24 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

MoltNode by Chord: MCP server

Read 31 blockchains and swap tokens from any AI agent. One hosted MCP server, no API key, no signup.

Read: JSON-RPC on Ethereum, Base, Arbitrum, Solana, Monad, BNB Chain, Avalanche, Sui and 23 more, through MoltNode (automatic failover across providers).
Trade: best-route swap quotes from Chord on Ethereum, Base, Monad, BNB Chain, Avalanche, Arbitrum, Robinhood Chain and Arc, with the unsigned transaction, the approval it needs and a simulation run from your wallet. Your agent signs with its own key; nothing is ever held for you.

https://moltnode.ag/mcp

Connect

Claude Code

claude mcp add --transport http moltnode https://moltnode.ag/mcp

Or install everything as a plugin (MoltNode + Chord MCP servers and the three skills):

/plugin install moltnode --marketplace tuantqse90/moltnode-mcp

Cursor, Windsurf, VS Code, Claude Desktop and any client that takes a URL

"mcpServers": { "moltnode": { "type": "http", "url": "https://moltnode.ag/mcp" } } }

In Claude Desktop or claude.ai you can also add it under Settings → Connectors → Add custom connector, with the URL above.

Clients that only start local commands (stdio)

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

(npx -y github:tuantqse90/moltnode-mcp works too.)

The stdio bridge in this repo (index.mjs) forwards every call to the hosted server, so both give the same tools. Without network it still lists the tools (from tools.json, a snapshot of the hosted list refreshed with npm run refresh-tools) and each call says the server is unreachable.

Tools

Tool	What it does
`list_chains`	Every chain MoltNode serves (slug, chainId, native coin, endpoint) and the ones Chord trades on
`rpc_call`	Any JSON-RPC method on any chain: `eth_call`, `eth_getLogs`, Solana `getBalance`, Sui methods, …
`get_block_number`	Latest block of an EVM chain
`get_balance`	Native-coin balance of an address on an EVM chain
`chord_find_token`	Token address, decimals and verified flag by symbol or name
`chord_swap_quote`	Best route across the chain's DEXs + unsigned `tx` + `approval` (as a ready transaction) + simulation from the taker wallet
`send_raw_transaction`	Broadcast a signed transaction

How an agent swaps

chord_find_token → the addresses and decimals of the two tokens (the zero address is the native coin).
chord_swap_quote with taker = the agent's wallet. Amounts are integer strings in the token's smallest unit (10000000 = 10 USDC).
If the answer has approval, sign and send approval.tx first.
Sign tx with the agent's own key.
send_raw_transaction on the same chain.

The router enforces minAmountOut on-chain. Chord's own router answers first; another aggregator is used only when Chord has no route, and the answer says which.

Agent skills

Install with the skills CLI (Claude Code, Codex, Cursor, Gemini CLI and more): npx skills add tuantqse90/moltnode-mcp, or in Hermes: hermes skills tap add tuantqse90/moltnode-mcp. Gemini CLI extension: gemini extensions install https://github.com/tuantqse90/moltnode-mcp.

skills/moltnode/: read 31 chains and swap through Chord end to end, with the safety rules (never handle a private key, confirm the quote before signing).
skills/chord-swap/: safe best-route token swaps through Chord on Ethereum, Base, Arbitrum, BNB Chain, Avalanche, Monad, Robinhood Chain, Arc and Solana: finds the right token, checks it for honeypots and taxes, quotes, waits for the user's yes, then returns an unsigned transaction with a simulation for the user's own wallet. Plain HTTP, no key, no scripts.
skills/chord-charts/: candlestick chart (SVG) with volume for any token on Ethereum, Base, Monad, BNB Chain, Avalanche, Arbitrum, Robinhood Chain, Arc or Solana, from Chord's trade data (python3 scripts/chart.py --chain base --token AERO --tf 1h).
skills/chord/: Chord's trading and market-data skill (quotes, unsigned swaps, token boards, candles, wallet PnL, smart money, holders, LP pools), marketplace edition: no key handling, no environment variables, no installer (generated from Chord's skill at nullterminal 5f07c02e; the Ask command, which needs a key, is left out). The original with Ask: https://getchord.xyz/docs/skills/chord/

skills/moltnode/SKILL.md is a SKILL.md skill (Claude Code, Codex CLI, Cursor, Gemini CLI, OpenClaw and others): when to read a chain, how to run a swap end to end, and the safety rules (never handle a private key, confirm the quote before signing). Install it by copying the folder into your agent's skills directory, e.g. ~/.claude/skills/moltnode/.
