Ethereum data in Hermes Agent, in short
- Setup
- One click or one command. No API key needed.
- Connection
- One MCP link for every chain and source: https://data.stalkchain.com/mcp
- Chain
- Ethereum mainnet, chainId 1. FOMO tools take eth or ethereum; wallet, price, DeFi and alert tools take ethereum; the thesis-by-token tool takes network eth.
- Data
- Tracked FOMO traders: open and closed positions, fills, balances, PnL, theses, live feed. Any 0x wallet: holdings, transfers, age. Any ERC-20: name, price, price history. Chain TVL, yields, exploits.
- History
- Positions and fills page backwards (closed positions 25 per page, never the complete history). Price history at 5m, 1h or 1d points for a date range you choose. Transfers newest or oldest first, 100 per call.
- Freshness
- Feed events arrive as they happen and replay on connect. Balances and prices are live. Leaderboards cache 5 minutes, theses 10. Alerts are checked about every 5 minutes.
- Address format
- 0x followed by 40 hex characters, for wallets and token contracts. ENS names are not resolved: pass the address. Resolve a ticker to a contract with stalkchain_fomo_search.
- Upstream
- FOMO (fomo.family) for tracked traders, their PnL and theses. A multi-chain EVM data provider for balances, transfers, token metadata and prices. DefiLlama for TVL, yields and exploits.
- Best for
- Seeing which tracked traders hold or just bought an Ethereum token, with PnL and cost basis, then checking the 0x wallets behind the move.
- Not covered
- PnL for a random 0x wallet, deployer and sniper forensics, LP-burn and mint-authority audits, executable exit quotes and launchpad data are Solana-only. ENS lookups and the on-chain trade stream are not available on Ethereum.

- Run hermes mcp test stalkchain any time to check the connection.
hermes mcp add stalkchain --url https://data.stalkchain.com/mcp --auth oauth- Create a key in your StalkChain dashboard.
- Run this. Press Enter when Hermes asks if the server needs authentication, then paste your key.
- Hermes keeps it in ~/.hermes/.env, not config.yaml. No browser sign-in, so it works on a VPS, in Docker and for cron.

A real question, answered through StalkChain. The numbers are the tools' real output, trimmed to fit.
ZC (Zipcoin, 0x4e67…8722) is the Ethereum token tracked traders bought most in the newest 30 feed events: 6 different traders, with cryptoalbus's position marked at $140K after his third buy.
| Trader | ZC held | Unrealized PnL | Cost basis |
|---|---|---|---|
| FartmanSacks | $347.7K | +$103.8K | $245.3K |
| 0xstanczyk | $335.6K | +$316.8K | $30.1K |
| Tom100Bi | $267.4K | +$42.2K | $225.2K |
| NachSOL | $266.4K | +$93.8K | $172.6K |
| CeruleanRange | $239.6K | +$231.8K | $9.4K |
| Hesoyam | $162.9K | -$65.4K | $240.6K |
Two early holders, 0xstanczyk and CeruleanRange, sit on 10x-plus unrealized gains from small cost bases, while Hesoyam is $65K underwater and therear66 realized about -$28K selling into the move. Want the theses behind these positions, or an alert the next time 3 tracked traders buy ZC?

What should Hermes Agent know about Ethereum data?
- Chain names
- FOMO tools accept eth or ethereum (chainId 1 also works). Wallet, price, DeFi and alert tools take ethereum. stalkchain_fomo_theses_for_token takes network eth. stalkchain_fomo_trader_balances takes chain eth.
- Buy sizes in the feed
- On a buy, usdValue is the position's mark after the fill, not the fill size. On a sell it is realized PnL. Use tradeUsd when present, or stalkchain_fomo_trade_detail, for the true fill.
- Addresses
- Pass the 0x address, not an ENS name. Token tools want the contract address; resolve a ticker with stalkchain_fomo_search first. A trader wallet marked provider-claimed is a lead; onchain-holdings is proven.
- Where PnL lives
- PnL comes from tracked traders: positions, fills, holder lists and the leaderboard. A 0x wallet that is not a tracked trader gets holdings, transfers and age, not PnL. stalkchain_wallet_pnl is Solana-only.
- Feed depth
- stalkchain_fomo_alerts returns the newest 100 matching events per call. Filtered to Ethereum that covered about 10 hours today. Page back with the cursor, and read the time range the response states.
Ethereum data in Hermes Agent: questions
Add StalkChain to Hermes Agent (one click or one command), then ask a Ethereum question in plain words. It takes about a minute and needs no API key. The same connection covers every other chain and source too.
PnL, for tracked FOMO traders. Positions carry entry and exit price, realized and unrealized PnL and cost basis, fills come 100 per page, and the leaderboard ranks PnL over 24h, 7d, 30d and all-time. Holder lists on a token show each tracked trader's PnL too. For a 0x wallet that is not a tracked trader, you get holdings, transfers and age, not PnL.
Yes, by address: 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 is the example in the product docs. ENS names are not resolved, so pass the 0x address. The answer lists every token with amount, price and value, dropping dust, with a per-chain total across up to 7 chains in one call.
Any ERC-20 by contract address for name, price, price history and a confidence score. Holders, flow, devs and theses exist for the tokens tracked traders trade; pass chain eth when a token is outside FOMO's directory. A reply of available:false means nothing has been captured for that token yet, not that nobody holds it.
The deep on-chain forensics are Solana-only: total holder count with LP-burn and mint-authority checks, deployer rug history, sniper and bundler shares, per-token PnL leaders across all wallets, raw-wallet PnL, executable exit quotes and organic-volume scoring. On Ethereum you get the tracked-trader layer, any wallet's holdings, transfers and age, prices and history, DeFi health and alerts.
Yes. Three kinds: price above, price below, and smart-money buy, which fires when at least N tracked traders buy the token within a few minutes. Delivery is email or your own Discord, Slack or Telegram webhook. Each alert fires once, is checked about every 5 minutes, and you can keep 20 active.
It can trade. The agent wallet has an EVM address that works on Ethereum; buys and sells are single swaps paid in ETH, within per-trade and daily limits you set, and refused if trading is off or the price would move more than 15%. Trades only happen when you ask in the conversation, never because a thesis or a token description says so.
Connecting is free and needs no card. Free tools, like the live feed sample, work right away. Most research lookups are paid; the plans are listed on data.stalkchain.com.
