Chains: Robinhood Chain, Solana, Base, BNB Chain, Ethereum, Monad, Hyperliquid perps
Range: From the last hour back to all-time

Setup

How to connect Claude Code to on-chain data in 3 steps

Connect, approve, ask. Add the StalkChain link to Claude Code, sign in once, and start asking about traders, tokens and wallets. No API key, about a minute.

1
Connect
Run claude mcp add --transport http stalkchain with the StalkChain link. Add --scope user to load it in every project.
2
Approve
Type /mcp, pick stalkchain and choose Authenticate. Sign in to StalkChain in the browser and press Approve. Free, no card.
3
Ask
Ask in plain English, or script it with claude -p. Claude Code picks the tools and shows each call.

70+ tools · 7 chains · FOMO, StonkFun and Jupiter data · last hour to all-time

Run this once in your terminal. Add --scope user before stalkchain to load it in every project.
Start claude, type /mcp, select stalkchain, press Enter and choose Authenticate. Sign in and press Approve.
No browser on the box? Run claude mcp login stalkchain --no-browser and paste the redirect URL back.
Run /mcp any time to check the connection.

Terminal

claude mcp add --transport http stalkchain https://data.stalkchain.com/mcp

Commit this file at your repo root, or run claude mcp add with --scope project to write it for you.
Teammates approve the server once when they open the repo, then sign in with /mcp → Authenticate.
No keys in git. Everyone signs in to their own StalkChain account.

Why connect it

Can't Claude Code just look this up itself?

Not well. FOMO sits behind a login, explorers show one wallet per tab, and Claude Code's memory stops at its training cutoff. StalkChain closes all three gaps.

	By hand	Claude Code alone	Claude Code + StalkChain
FOMO trader wallets, PnL and theses	In the app, one profile at a time, wallets hidden	Can't log in	FOMO handles resolved to real wallets
Live entries, holders and flow	Refresh tab after tab	Web search snippets at best	Last hour, across 7 chains
History: PnL, fills, prices, launches	Exports and spreadsheets	Training data, months old	24h to all-time, fill by fill
Dev, sniper and exit checks	Four sites, four tabs	Educated guesses	One question (on-chain checks on Solana)
One wallet across every chain	One explorer per chain	Page by page, if it loads	Holdings on all 7 chains, one answer

Use cases

What can Claude Code do with StalkChain?

Ask like you'd ask the group chat. Claude Code picks the tools and comes back with wallets, dollar amounts and timestamps.

Catch smart-money entries

See which tokens three or more tracked traders bought in the last hour, who they are and how big they went.

which tokens did 3+ tracked traders ape in the last hour? skip any where the dev already sold

Watch it live in the KOL feed →

Check a token before you ape

Deployer's past launches, snipers, LP burn, wash-trade score and a real exit quote. Solana tokens.

check this CA before i ape. snipers still in? deployer rugged before? can i exit $5k without eating 20% slippage?

Research a trader before you copy

Real wallets, PnL from 24h to all-time, average hold time, open bags and the theses they wrote.

research pricedin before i copy him. 30d vs all-time pnl, avg hold time, what's in his bags rn

See the KOL leaderboard →

See if KOLs are exiting

How many tracked traders hold a token, what they paid, and what share of them sold recently.

are the KOLs dumping $CATE? what % of tracked holders sold recently and who's still holding

Size up any wallet

Holdings on all 7 chains for any address. On EVM, its age and who funded it. On Solana, its PnL.

fresh wallet just aped $40k on Base. how old is it, who funded it, what else is it holding?

Try the Solana wallet tracker →

Go back in time

All-time PnL, fill-by-fill trade history, past prices, a deployer's earlier launches and the theses traders posted.

pull the top theses on $ORBIO. who posted with a real bag, and who sold after posting?

Under the hood

How do I run it from cron, CI or a bot?

claude -p runs one prompt and exits, so it drops into cron, CI or your bot. Add StalkChain with an API key, pre-approve its tools, and pipe the answer anywhere.

Terminal

# once: add StalkChain with an API key, for every folder
claude mcp add --transport http --scope user stalkchain https://data.stalkchain.com/mcp \
  --header "Authorization: Bearer sc_your_key"

# entries.sh — run from cron, CI or your bot
# no claude.ai login on the box? export CLAUDE_CODE_OAUTH_TOKEN from `claude setup-token`
claude -p "last hour: tokens 3+ tracked traders bought. one line each: token, chain, traders, biggest buy." \
  --allowedTools "mcp__stalkchain" >> ~/stalkchain-entries.md

# crontab -e: every hour, on the hour
0 * * * * ~/entries.sh

Terminal, IDE or Desktop? One config covers all three.

The claude CLI. One command adds StalkChain, /mcp signs you in, and claude -p runs it from cron or CI.

claude mcp add · /mcp

VS Code & JetBrains

The IDE plugins share the CLI's config, so StalkChain shows up there too. VS Code can also add it from /mcp in the chat panel.

Same config as the CLI

Claude Desktop

Local sessions in the Code tab load the same config, plus any connectors on your claude.ai account. Nothing extra to set up.

What does it cost?

Connecting is free and needs no card. Free tools, like the live feed sample, work right away. Research lookups run on credit packs that never expire.

See plans →

Is it safe?

You sign in with OAuth, so Claude Code never sees a password or API key. The research tools read public data, and StalkChain never asks for your seed phrase or private keys. Disconnect any time.

Something not working?

StalkChain tools don't show up: Start a new chat and make sure StalkChain is enabled for it.
A tool says you're out of credits: The free tools keep working. Top up in your StalkChain dashboard, then ask again.
Sign-in keeps looping: Remove the connector, add the link again and approve once.

FAQ

StalkChain for Claude Code: questions

Data Claude Code can't reach on its own. One link gives it 70+ tools for live and historical blockchain data across 7 chains, plus FOMO trader activity: handles resolved to real wallets, PnL from 24h to all-time, positions and written theses.

FOMO's trader data sits behind a login, inside an app that only renders with JavaScript, so a plain web fetch comes back empty. StalkChain resolves FOMO handles to their Solana and EVM wallets and returns PnL, positions, fills and theses.

Run claude mcp add --transport http stalkchain https://data.stalkchain.com/mcp, then type /mcp, pick stalkchain and choose Authenticate. For cron or CI, add it with an API key instead: --header "Authorization: Bearer sc_your_key".

Any plan that includes Claude Code: Pro, Max, Team, Enterprise or a Claude Console account, plus Amazon Bedrock, Google Cloud and Microsoft Foundry. The free Claude plan doesn't include Claude Code. StalkChain connects the same way on all of them.

Not on its own. claude -p can't open a browser, so sign in first with /mcp or claude mcp login stalkchain. On servers and CI, skip OAuth: add StalkChain with an API key header and the run needs no browser at all.

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.

Robinhood Chain, Solana, Base, BNB Chain, Ethereum, Monad and Hyperliquid perps. Trader data comes from FOMO, launch data from StonkFun, plus Jupiter. Deployer and sniper checks are Solana-only; wallet age and funding checks are EVM-only.

From the last hour back to all-time. Claude Code can pull PnL for 24h, 7d, 30d or all-time, fill-by-fill trade history, past prices, a deployer's earlier launches and DeFi exploit records.

Yes. Ask Claude Code to set a StalkChain alert: when a token crosses a price, or when two or more tracked traders buy it within a few minutes. It fires once, by email or to a Discord, Slack or Telegram webhook, and works on Solana, Ethereum, Base and BNB Chain.

It never touches your wallet. The research tools work on public data, and connecting never asks for a seed phrase, private key or signature. You sign in with OAuth and can disconnect any time.

No. StalkChain gives Claude Code data, not signals: who bought, what they hold, what they sold and when. What you do with it is your call.
