name: openpump description: Solana token launch and trading tools via OpenPump MCP server. Use when creating tokens on pump.fun, buying or selling tokens, transferring SOL or SPL tokens, checking wallet balances, managing wallets, getting token quotes, or monitoring portfolio and creator fees. Covers all pump.fun operations including bundle buys, bundle sells, Jito priority, bonding curve analytics, and mcp trading workflows. Keywords: solana trading, token launch, token operations, openpump.

OpenPump MCP Skill

Trade pump.fun tokens, manage Solana wallets, and monitor positions -- all from within Claude Code via MCP.

When to Use This Skill

• Launching a new token on pump.fun
• Buying or selling pump.fun tokens
• Checking wallet balances or token holdings
• Transferring SOL or SPL tokens between wallets
• Getting price quotes before trading
• Monitoring creator fees
• Coordinating multi-wallet bundle buys or sells
• Querying token analytics and risk metrics

When NOT to Use This Skill

• On-chain queries outside pump.fun -- use the solana-cli skill for general Solana RPC data
• Wallet key management -- OpenPump uses custodial HD wallets; you cannot import external private keys
• DeFi beyond pump.fun -- Raydium, Orca, Jupiter swaps are not supported
• NFT operations -- this is fungible token only

Workflows

1. Launch a Token

1. create-wallet (label: "launch-wallet")
2. Fund the wallet with SOL (use get-wallet-deposit-address for the address)
3. create-token (name, symbol, description, imageUrl)
4. poll-job (wait for confirmation)
5. get-token-info (verify token is live on pump.fun)

2. Buy and Sell Flow

1. list-wallets (find walletId with SOL balance)
2. get-token-quote (action: "buy", solAmount in lamports) -- preview first
3. buy-token (mint, walletId, amountSol in lamports)
4. get-token-holdings (mint) -- verify purchase
5. get-token-quote (action: "sell", tokenAmount) -- preview sell
6. sell-token (mint, walletId, tokenAmount or "all")

3. Check Portfolio

1. list-wallets -- see all wallets
2. get-aggregate-balance -- total SOL across wallets
3. get-token-holdings -- all token positions (omit mint for everything)
4. get-token-market-info (per mint) -- current prices and risk metrics

4. Claim Creator Fees

1. get-creator-fees -- check all wallets for accumulated fees
2. claim-creator-fees (creatorAddress)
3. get-wallet-balance (walletId) -- verify SOL increased

5. Bundle Launch (Multi-Wallet)

1. create-wallet (multiple, label each by purpose)
2. Fund wallets with SOL
3. estimate-bundle-cost (buyWalletCount, devBuyAmountSol, walletBuyAmounts)
4. bundle-buy (devWalletId, buyWalletIds, tokenParams, amounts, confirm: true)
5. poll-job (wait for confirmation)
6. get-token-holdings (mint) -- verify all wallets hold the token

6. Transfer SOL Out

1. get-wallet-balance (walletId) -- check available SOL
2. transfer-sol (walletId, toAddress, amountLamports, dryRun: true) -- preview
3. transfer-sol (walletId, toAddress, amountLamports) -- execute

Safety Best Practices

1. Always check balances first. Before any trade or transfer, run get-wallet-balance or get-aggregate-balance to verify you have sufficient SOL.

2. Use quotes before trading. Call get-token-quote before buy-token or sell-token to preview the expected output and price impact.

3. Confirm large trades explicitly. Bundle operations require confirm: true. Never set confirm without reviewing the parameters.

4. Verify addresses on transfers. Double-check the destination address before calling transfer-sol or transfer-token. Transfers are irreversible on Solana.

5. Use dryRun for transfers. Both transfer tools support dryRun: true to validate inputs and estimate fees without submitting.

6. Check risk metrics. Use get-token-market-info to check sniper count, bundler activity, and insider percentage before buying.

7. Understand priority levels. Jito priority tiers (economy/normal/fast/turbo) affect transaction speed and cost. Use get-jito-tip-levels to see current rates.

8. Monitor async operations. After create-token or bundle-buy, call poll-job every 2 seconds until status is "completed" or "failed". Jobs expire after 10 minutes.

9. Transfer cap. transfer-sol has a hard cap of 10 SOL per call. For larger amounts, split into multiple calls.

10. Bundle buy legal notice. Coordinated multi-wallet purchases (bundle-buy) may have legal implications. Review the RICO disclaimer before using.

Key Concepts

• Lamports: SOL amounts are in lamports (1 SOL = 1,000,000,000 lamports). Always pass as decimal integer strings, not floats.
• Token base units: Token amounts use raw base units (not UI decimals). Use the exact string from get-token-holdings.
• Custodial wallets: All wallets are HD-derived and managed by the platform. You cannot import external keys.
• Bonding curve: pump.fun tokens trade on a bonding curve until they graduate to PumpSwap. bundle-sell only works on bonding curve tokens.
• Jito bundles: Bundle operations use Jito MEV for atomic, same-block execution (first 3 wallets guaranteed).
