8 CIPHER tools — Solana scan, breach check, Jito, FRED, Drift, repo health, more. x402-paid on Base.
Remote MCP server exposing Solana, crypto, macro and research tools that are mostly paid per call in USDC on Base via the x402 protocol.
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/io.github.cryptomotifs%2Fcipher-x402-mcp/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.

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.
Prefer not to self-host? A managed listing is live on MCPize with gateway proxying, rate limiting, API-key auth, and consolidated billing:
mcpize.com/mcp/cipher-x402-mcp
Pay-as-you-go via MCPize's gateway. Self-host is still free (this repo, MIT).
Base network, USDC asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913. The
current x402 payout recipient is exposed via the root / JSON manifest at
runtime — agents discover it automatically, you don't configure it by hand.
Add this to ~/Library/Application Support/Claude/claude_desktop_config.json
(macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
Restart Claude Desktop. The 8 tools show up in the tool tray.
Any MCP-over-stdio client works the same way — the launcher is
npx -y cipher-x402-mcp.
Deployed at https://cipher-x402-mcp.vercel.app/mcp (streamable HTTP). Probe the manifest at the root URL.

All upstream base URLs are overridable via env — useful if you fork the upstream endpoints to your own Vercel project and want the MCP server to route to them:
The /mcp route serves MCP JSON-RPC messages; / serves a lightweight
JSON manifest used by registries.
A few small paid sidecars if the MCP is useful and you want to go deeper — all direct-pay, no platform middleman:
