Scopes—claude mcp addwrites to one of three places; choose with--scope:

Use--scope projectonly when you want the servercommitted into a specific repo— it writes a.mcp.jsonthat teammates must approve on first use. For a general-purpose tool like this,--scope useris the right default.

Edit the config file (create it if missing), then restart Claude Desktop:

- macOS—~/Library/Application Support/Claude/claude_desktop_config.json
- Windows—%APPDATA%\Claude\claude_desktop_config.json

Claude Desktop, Cursor, and a Claude Code.mcp.jsonall use the identical shape:

Config-file clients (Desktop / Cursor /.mcp.json):put it in theenvblock above.

Claude Code:re-run the add with--env(note: this is saved to~/.claude.json; avoid leaving the raw secret in your shell history):

Your key never leaves your machine, is used only to sign locally, and is redacted from all output. Every money-moving action is simulated before it is sent.

Once it's registered, just talk to your agent naturally:

The agent resolves names to mint addresses withsearch_tokens/search_nfts, then acts on the mint — it never turns a name straight into a trade.

Reads(no key):chain_health,get_pools,get_token_info,search_tokens(resolve a token name/ticker to its mint),get_quote,get_wallet(which key this server signs with, and the RPC it uses — no RPC call, so it works when the chain is down),get_balance,stake_info(bCOOK liquid-staking rate / TVL / APY / fees), launchpad readsget_launchpad_pools/get_launchpad_token/get_launchpad_positions, and NFT readsget_nft_listings,search_nfts(resolve an NFT/collection name to a listed mint),get_nft,get_wallet_nfts,get_nft_offers,get_nft_market_stats, and.cookname readsresolve_domain/get_owned_domains/get_domain_listings.

⚠️Before graduation, holdings are program-tracked curve shares, not SPL tokens— they do not appear inget_balanceandtradecannot route them. Exit withlaunchpad_sell, or claim the real token withclaim_launchpadonce the pool graduates; from then on it trades like any other token.

Because those shares are invisible toget_balance,get_launchpad_positionsis the portfolio view: every launch a wallet has a position in, what it is worth on a live curve, and what is unclaimed (tokens after graduation, a Fair-mode refund, a settlement payout, creator fees or vesting). It reads theUserPositionaccounts straight from the chain in batches, so it costs about one RPC round trip per 100 launches. Passownerfor any wallet, or omit it for your own.

A pre-graduation token also has no DEX pool at all, soget_quote/tradewould just report "no route". They now recognise that case and point at the launchpad tools instead, andget_token_infoadds alaunchpadfield when a mint shows no price or liquidity because it is still on a curve.

⚠️Listing escrows the name.list_domainhands the domain to the marketplace's escrow account in the same instruction, so while it is listed the registry reports the escrow as its owner: the seller cannottransfer_domain,update_domainorset_primary_domainon it, and it stops resolving to a payable address. Those tools say so explicitly rather than reporting a stranger as the owner, and passing a listed name where an address is expected isrefused— the escrow is a program account, so paying it would strand the funds.cancel_domain_listingreverses a listing at any time and refunds its rent. There is no re-price instruction: cancel, then list again.

buy_domainrequiresmaxPriceCookfor the same reasonregister_domaindoes — the instruction carries no price argument, so that cap is the only guard. Without it you get the asking price quoted back and nothing is spent.

Use the COOK / native mintSo11111111111111111111111111111111111111112for COOK. Every tool returns JSON; failures return{ error, hint }— never a stack trace, never your key.
