MCP support
Its remote MCP server exposes tools for token checks, safety-checked swaps, and listing paid data endpoints. Token checks include five free calls per day, then use x402 payments.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Details
From the project READMEMOSN — Solana token safety, fresh alpha & safe swaps for AI agents
MOSN is an autonomous Solana agent that screens every brand-new token in real time (PumpSwap + Raydium CPMM pool creations, seconds after launch) and sells what it learns — pay-per-call, no API key, no signup.
- 🛡️ Rug / safety checks — mint & freeze authority, dangerous Token-2022 settings, real-wallet holder concentration (pools excluded), live sell-route round-trip test
- 🆕 Real-time new pools — straight from on-chain pool-creation logs
- ⚡ Fresh Solana alpha — new tokens that passed MOSN's screens, with its AI verdict + live market data
- 📊 Labeled memecoin dataset — features + what the price did 5/10/15 min later
- 🔁 Safe Swap — refuses buys into DANGER tokens, returns an unsigned Jupiter swap for your wallet

🤖 For people: Telegram bot
@MOSNSafeSwapBot — send any Solana token address or pump.fun / DexScreener link and get a rug-check verdict in seconds plus one-tap Buy / Sell buttons. You sign in your own Phantom or Solflare wallet; MOSN never holds keys or funds. 0.5% fee (half of most Telegram trading bots). Refuses to route buys into DANGER tokens.
📣 Free alerts channel: @MOSNAlpha — new Solana tokens that passed MOSN's rug checks, posted in real time.

Tools:
| Tool | What it does | Cost |
|---|---|---|
mosn_token_check | SAFE / CAUTION / DANGER verdict with reasons | 5 free/day, then x402 |
mosn_safe_swap | Safety-checked Jupiter swap tx for your wallet | free (0.3% platform fee) |
mosn_paid_endpoints | Lists the paid data endpoints | free |
Pay-per-call HTTP API (x402 — USDC on Solana or Base)
| Endpoint | Price |
|---|---|
GET /token-check?mint=<mint> | $0.005 |
GET /holders?mint=<mint> | $0.002 |
GET /new-pools?minutes=15 | $0.01 |
GET /alpha?minutes=30 | $0.05 |
GET /dataset?hours=24 | $0.25 |
GET /safe-swap?mint=&side=buy&amountSol=0.1&wallet=<pubkey> | free + 0.3% fee |
Any x402 client works, e.g. @x402/fetch:
import { wrapFetchWithPayment, x402Client } from '@x402/fetch';
// register your Solana (or Base) signer with x402Client, then:
const res = await payFetch('https://mosn-api.mosn-3r41y.workers.dev/token-check?mint=JUPyiwrYJFskUPiHa7hkeR8VUtAeFoSYbKedZNsDvCN');

Honest numbers
New Solana tokens are extremely risky. In MOSN's own tracking, roughly 1 in 4 brand-new tokens that passed basic scam checks still crashed 50%+ within 15 minutes. MOSN's checks reduce risk; they don't remove it. Not financial advice.
Daily public reports
MOSN publishes a free daily "Solana new-token report" from its own data — see the links in REPORTS.md.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
