What the code does

A tool parameter reaches a dangerous call
A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

That is not a flaw by itself — but it is where things go wrong when it is not the job. We re-read this code on every release. Watch it and you hear from us the day another one appears.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
pumpfun
pumpfun_bot_status
Returns the configuration and health status of the pump.fun indexer backend. Always available; does not require PUMPFUN_BOT_URL. Use this first when search_tokens, get_graduated_tokens, get_king_of_the_hill, or get_creator_profile fail or are missing, to see whether the indexer is configured and healthy.
pumpfun_first_claims
First-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. Use this to spot creators cashing out for the first time across all coins; for one creator's history call pumpfun_list_claims.
pumpfun_list_claims
List 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. Creator fees from the v3 curve and v2 pool trades wait on the curve and pool until a sweep_creator_fee moves them to the creator vault, so a claim covers only what was swept (usually in the same transaction) and fees still waiting appear in no claim yet. Use this to audit how much a creator has already cashed out; for only the claims inside a recent window call pumpfun_watch_claims.
pumpfun_quote_swap
Read-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, a SIGNED i128 that is commonly negative because PumpSwap v2 trades keep waiting protocol and creator fees in the vault and subtract them there); 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. Use this to size a trade on a graduated coin, or to measure its pool depth, before executing anywhere.
pumpfun_upload_metadata
Upload 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_vanity_mint
Generate 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. Use this before launching a coin when its mint address should carry a recognizable prefix or suffix.
pumpfun_watch_claims
Return all pump.fun fee-claim events for a creator wallet within a look-back window (durationMs). Use this for batch collection after a delay; for a creator's full recent claim history call pumpfun_list_claims.
pumpfun_watch_whales
Collect whale trades on a pump.fun token for a short window (max 10 s). Returns all trades whose USD value meets minUsd. Use this to see who is moving size on a coin right now; for the full recent tape call get_token_trades.
token
get_token_details
Full details for a specific pump.fun token by mint address. Use this when you already have a mint and need its metadata, market cap, and curve status; for holder concentration call get_token_holders, for recent fills call get_token_trades.
get_token_holders
Top holders of a token with concentration analysis (on-chain). Use this to check whether a few wallets control the supply before buying; for price and volume call get_token_details instead.
get_token_trades
Recent buy/sell history for a token. Use this to read recent buy and sell flow on one coin; to see only large trades as they land, call pumpfun_watch_whales instead.
sns
sns_resolve
Resolve a .sol Solana Name Service domain to its owner wallet address. Use this when a wallet is named by its .sol domain and you need the address; for the reverse direction call sns_reverseLookup.
sns_reverseLookup
Reverse-lookup a Solana wallet address to its primary .sol domain name. Use this to label a raw wallet address with its human-readable .sol name; to go from name to address call sns_resolve.
social
social_cashtag_sentiment
Score social-post sentiment for a cashtag using a deterministic lexicon. Returns score (-1..1), positive/negative/neutral percentages, and example posts. Use this to score posts you have already collected; it fetches nothing itself, so pass the posts in.
social_x_post_impact
Correlate 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. Use this to measure how one X post moved a coin that is still on its bonding curve (pricing is virtual_quote_reserves / virtual_token_reserves); a graduated coin has no curve, so the call fails rather than returning a zero price.
bonding
get_bonding_curve
Bonding 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. A v3 buy that empties the curve completes it and buys the rest through a synthetic migration, priced on the reserves the PumpSwap pool will open with, so a large final buy is not capped at realTokenReserves. Once complete=true the curve is retired and pricing moves to the PumpSwap pool, so use pumpfun_quote_swap from that point on. Use this to read graduation progress or the curve spot price of a coin that has not graduated yet.
coin
get_coin_intel
Full 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.
kol
kol_leaderboard
Top KOL traders ranked by P&L for a given time window. Returns wallet, pnlUsd, winRate, trades, rank. Use this to find which trader wallets are worth following; to see whether they hold a given coin, call get_coin_intel or get_token_holders.
new
get_new_tokens
Most recently launched pump.fun tokens. Use this to catch launches in their first minutes; for the largest coins by market cap call get_trending_tokens instead.
oracle
get_oracle_conviction
Oracle 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.
trending
get_trending_tokens
Top pump.fun tokens by market cap. Use this to scan the largest coins on pump.fun right now; for fresh launches call get_new_tokens, for coins that left the curve call get_graduated_tokens.

It exposes 21 tools, read directly from the server on our last check. Among them: get_bonding_curve, get_coin_intel, get_new_tokens, get_oracle_conviction, get_token_details, get_token_holders and 15 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
What is three.ws pump.fun MCP mostly used for?
Its tools cluster around pumpfun, token and social. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is three.ws pump.fun MCP working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 272 ms. The bar chart above shows every period we have measured.
How do I connect three.ws pump.fun MCP?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does three.ws pump.fun MCP need an API key?
No. three.ws pump.fun MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 21 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is three.ws pump.fun MCP?
It answers our handshake in 272 ms on average, which is faster than 53% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is three.ws pump.fun MCP open source?
The code is open source: it is published under the Apache-2.0 licence, written in JavaScript, 264 stars on GitHub and 6 open issues. The licence covers the code in the repository, not the hosted service at three.ws, which runs on its operator's own terms.
