Tools

Tool	Arguments	Returns
fee_quote	surface, stage (curve, pumpswap), market_cap, amount_usd, quote (SOL or USDC), round_trip, new_token, custom_pair	The fee stack for one trade: pump.fun's creator, protocol and LP fees for the coin's stage and market-cap tier, the app's 0.45% or 0.40% Platform Fee, and the trading app's own fee. Totals with and without a referral link, each line in percent and USD, and optionally the buy-and-sell round trip.
route_cost	stage, market_cap, amount_usd, quote, referral, new_token	The same trade priced on all 15 surfaces we track (pump.fun app, Terminal, Axiom, GMGN, fomo, Photon, Telegram bots, Phantom, Jupiter Ultra and Manual), sorted by total fee. Apps that don't publish a fee are listed separately.
coin_check	mint (Solana address, or a pump.fun or DexScreener link)	PumpFYI's coin checker, the same one as on /coin/: a 0–100 risk score and verdict, stage (bonding curve or graduated), mint and freeze authority, holder concentration, liquidity and copycats, each check with its source and the read time.
get_referral_info	venue (default pump-fun, or "all")	What a referral link documents for you (pump.fun: 0.40% instead of 0.45%), what the program pays the referrer, the source, and the PumpFYI link.
search_site	q, limit	PumpFYI pages for a question: fees, guides, explainers, where to trade, comparisons, data and news.

Every tool returns a readable text answer plus structuredContent with the raw numbers and sources; coin checks include the full checker result and the time of the read (checked_at). All tools are read-only: none can sign, send or trade.

Try it with curl

curl -s https://pumpfyi.com/mcp \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

curl -s https://pumpfyi.com/mcp \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call",
       "params":{"name":"fee_quote","arguments":{"amount_usd":100,"stage":"curve"}}}'

That call returns the fee stack for a $100 bonding-curve buy in the pump.fun app: 1.25% in pool fees plus the 0.45% Platform Fee, 1.70% ($1.70) in total, or 1.65% ($1.65) with a referral code.

Data rules

• Fee rates come from the same engine as our fee calculator: pump.fun's Fees page and each trading app's own documentation. When a source changes, the calculator and the tools change together; the methodology page explains the math.
• Fees exclude Solana network fees, priority fees, tips and slippage.
• Every valid pump.fun referral code gives the same 0.40% Platform Fee. Codes only decide who is paid; none gives a bigger discount.
• route_cost ranks by total fee only. It never ranks by what a venue pays referrers.
• Referral links are PumpFYI's own; we earn a share of fees from them (disclosure). That never changes the data.
• Coin checks flag risks; they never call a coin safe. Most pump.fun coins lose most of their value, and nothing returned is financial advice.
• pump.fun's terms prohibit the UK and sanctioned countries. The server never suggests ways around that.
