CIPHER x402 — Paid Solana & Crypto Tools
A crypto-focused toolkit that wires eight tools into Claude: Solana wallet scanning, HIBP password breach checks, Jito MEV tip calculation, GitHub repo health scoring, FRED macro data lookups, Drift protocol exposure checks, wallet security rules, and premium cipher chapters. Seven of the eight are gated behind x402, a pay-per-call protocol that settles in USDC on Base (0.5 to 25 cents per invocation). The server is a stateless relay that surfaces HTTP 402 responses to the agent, which then auto-signs an EIP-3009 payment authorization and retries. No API keys, no custody. You can self-host via npx or use the managed MCPize plans if you want rate limiting and consolidated billing. Built for agents that need on-demand access to Solana and macro primitives without standing subscriptions.

cipher-x402-mcp
An MCP server that exposes 8 Solana / crypto / macro tools to any MCP-aware client (Claude Desktop, Cursor, Cline, Continue, etc.). Seven of the tools are gated behind the x402 payment protocol — agents auto-pay in USDC on Base, $0.005 – $0.25 per tool call. One tool is free (educational).
The server is a forward-only relay: when an agent calls a paid tool without an
X-PAYMENTheader, we surface the upstreamHTTP 402+ accept-list verbatim so the agent's own wallet signs the payment. We never custody caller funds.
Free + MIT-licensed. Fork it, ship your own, no strings.
