Solana token rug checks and safety-checked Jupiter swaps for AI agents; paid data via x402.
Remote MCP server that gives an assistant Solana token rug/safety verdicts and safety-checked Jupiter swap transactions, plus a list of paid x402 data…
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/dev.workers.mosn-3r41y.mosn-api%2Fmosn/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}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.

@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.

Any x402 client works, e.g. @x402/fetch:
Machine-readable: /openapi.json · /.well-known/x402 · /.well-known/agent.json · /llms.txt
Also on Virtuals ACP (search "MOSN"): token checks, holder checks, new-pool snapshots, fresh alpha, labeled dataset, crypto research briefs.
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.
MOSN publishes a free daily "Solana new-token report" from its own data — see the links in REPORTS.md.

Rug/safety check for a Solana token: mint & freeze authority, dangerous Token-2022 settings, real-wallet holder concentration (pools excluded), live sell-route test. Returns SAFE/CAUTION/DANGER with reasons. 5 free checks per day, then use the paid x402 endpoint.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
