    Server tool list (21)

    Raw names from tools/list. Only developers need these.

    get_token_detailsFull details for a specific pump.fun token by mint address.
    get_bonding_curveBonding curve analysis: real reserves, virtual reserves, and graduation progress (on-chain). Pre-graduation only: these reserves come from the pump program bonding-curve account, not from a PumpSwap pool. Pump renamed the quote-side fields on-chain (real_sol_reserves -> real_quote_reserves, virtual_sol_reserves -> virtual_quote_reserves) once a non-SOL quote asset became possible; the response keys below keep their original names and are still denominated in SOL, because the curve quote_mint is the SOL default on every coin created to date. Once complete=true the curve is retired and pricing moves to the PumpSwap pool, so use pumpfun_quote_swap from that point on.
    get_token_tradesRecent buy/sell history for a token.
    get_trending_tokensTop pump.fun tokens by market cap.
    get_new_tokensMost recently launched pump.fun tokens.
    get_token_holdersTop holders of a token with concentration analysis (on-chain).
    pumpfun_vanity_mintGenerate a Solana keypair whose address ends/starts with a vanity pattern. Returns publicKey + secretKey (base58). Caller must save the secret key immediately — it is never stored. Hard timeout: 60 s.
    pumpfun_watch_whalesCollect whale trades on a pump.fun token for a short window (max 10 s). Returns all trades whose USD value meets minUsd.
    pumpfun_list_claimsList recent pump.fun fee-claim events for a creator wallet (on-chain, no indexer needed). Returns signature, mint, lamports, and Unix timestamp for each claim.
    pumpfun_watch_claimsReturn all pump.fun fee-claim events for a creator wallet within a look-back window (durationMs). Useful for batch collection after a delay.
    pumpfun_first_claimsFirst-ever pump.fun creator fee claims in a time window: a cash-out signal. Returns creators who have never claimed before, with creator wallet, mint, lamports, and timestamp.
    sns_resolveResolve a .sol Solana Name Service domain to its owner wallet address.
    sns_reverseLookupReverse-lookup a Solana wallet address to its primary .sol domain name.
    social_cashtag_sentimentScore social-post sentiment for a cashtag using a deterministic lexicon. Returns score (-1..1), positive/negative/neutral percentages, and example posts.
    kol_leaderboardTop KOL traders ranked by P&L for a given time window. Returns wallet, pnlUsd, winRate, trades, rank.
    pumpfun_quote_swapRead-only price quote for a pump.fun AMM (PumpSwap) swap. No signing or tx sending. One of inputMint/outputMint must be wSOL (So11111111111111111111111111111111111111112). Only GRADUATED coins have an AMM pool; for a coin still on its bonding curve use get_bonding_curve instead. Pricing runs on the pool effective quote reserves (quote vault balance + pool.virtual_quote_reserves); the base side is the raw base vault balance. Returns amountOut, priceImpactBps, route, expiresAtMs, plus the reserves the quote was computed from so the number can be reproduced.
    social_x_post_impactCorrelate an X (Twitter) post to a memecoin price impact. Fetches post metadata via oEmbed (no API key) and computes price delta from the pump.fun bonding curve in a ±windowMin window around the post.
    get_coin_intelFull Coin Intelligence snapshot for a pump.fun mint. Returns every signal the engine recorded during the observation window: bundle vs organic verdict, bubblemaps-style cluster connectivity, smart-money presence (with wallet labels and win-rates), dev behaviour, category/classification, news-meme detection with the matching headline, risk flags, and a 0–100 quality score. Also returns the outcome if the coin is old enough to be labeled (graduated/rugged/ATH multiple). This is the single highest-signal read for a trade decision — call this before entering any position.
    get_oracle_convictionOracle conviction score for a pump.fun mint: the fused 0-100 score the Oracle engine produces by combining four intelligence pillars: pedigree (who bought it), structure (organic vs bundle, holder concentration, bubblemaps connectivity), narrative (category, meme virality, news hook), and momentum (timing, velocity). Returns the tier (prime ≥86 / strong ≥72 / lean ≥54 / watch ≥36 / avoid), the per-pillar breakdown, the natural-language reasons that drove the score, the full "who's in" trader roster with reputation labels and win-rates, and the narrative read (category, virality, tags). Call this when you need the highest-confidence trade signal; it synthesises everything get_coin_intel exposes into one actionable score. Pairs with get_coin_intel for raw signals.
    pumpfun_upload_metadataUpload coin metadata (name, symbol, description, image) to IPFS and get back a pump.fun-ready metadata URI. Call this before launching a coin — pass the returned uri to the launch-agent endpoint or the studio launch flow. Requires a valid bearer token (API key). Image may be a public HTTPS URL or a base64 data URI (max 10 MB). The returned uri is a permanent ipfs:// link; the call is idempotent for the same content.
    pumpfun_bot_statusReturns the configuration and health status of the pump.fun indexer backend. Always available — does not require PUMPFUN_BOT_URL.
