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-PAYMENT` header, we surface the upstream `HTTP 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. --- ## Hosted Plans (MCPize) 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](https://mcpize.com/mcp/cipher-x402-mcp)** | Plan | Price | Requests / mo | Rate limit | Includes | |------|-------|---------------|------------|----------| | Free | $0 | 100 | 10 / min | Free tools + `solana_wallet_scan` | | Starter | $9 | 1,000 | 60 / min | 4 read-only tools (scan, HIBP, repo health, FRED) | | Pro (recommended) | $29 | 5,000 | 120 / min | All 8 tools, priority GitHub support | | Team | $99 | 25,000 | 600 / min | All 8 tools + custom upstream override, 24h response SLA | Pay-as-you-go via MCPize's gateway. Self-host is still free (this repo, MIT). --- ## Tools | Tool | Price (USDC, Base) | Upstream | |------|--------------------|----------| | `solana_wallet_scan(address)` | $0.01 | `cipher-scan-three.vercel.app` | | `check_password_breach(sha1_prefix)` | $0.005 | `cipher-pwned.vercel.app` | | `jito_tip_calculator(pool_depth, expected_profit, slot_prob)` | $0.01 | `cipher-jito-tip.vercel.app` | | `github_repo_health(owner, repo)` | $0.02 | `cipher-repo-health.vercel.app` | | `fred_macro_series(series_id)` | $0.005 | `cipher-fred.vercel.app` | | `check_drift_exposure(wallet)` | $0.01 | `cipher-drift-exposure.vercel.app` | | `solana_wallet_security_audit_rules()` | **free** | local (v1.1.0 ruleset) | | `get_premium_cipher_chapter(slug)` | $0.25 | `cipher-x402.vercel.app` | 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. ## Install (Claude Desktop) Add this to `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS) or `%APPDATA%\Claude\claude_desktop_config.json` (Windows): ```json { "mcpServers": { "cipher-x402": { "command": "npx", "args": ["-y", "cipher-x402-mcp"] } } } ``` Restart Claude Desktop. The 8 tools show up in the tool tray. ## Install (Cursor / Cline / Continue) Any MCP-over-stdio client works the same way — the launcher is `npx -y cipher-x402-mcp`. ## Install (Smithery) ```bash npx -y @smithery/cli install cipher-x402-mcp --client claude ``` ## Remote HTTP transport Deployed at **https://cipher-x402-mcp.vercel.app/mcp** (streamable HTTP). Probe the manifest at the root URL. ## How payment works 1. Agent calls (e.g.) `solana_wallet_scan({ "address": "..." })` without a payment. 2. Server returns a structured result starting with `HTTP 402 Payment Required — upstream returned an x402 accept-list.` followed by the JSON accept-list (price, network, payTo, asset, etc.). 3. Agent's wallet signs an EIP-3009 authorization for the advertised `maxAmountRequired`. 4. Agent re-invokes the same tool with `{ "address": "...", "_payment": "" }`. 5. Server forwards the `X-PAYMENT` header upstream, upstream's facilitator verifies + settles on Base, and the content is returned to the agent. The server itself is stateless — no API keys, no user session, no funds. --- ## 🏃 Run it yourself ### Prerequisites - **Node.js 20+** (22 recommended) - **npm 10+** - A Vercel account (free tier) if you want to deploy the HTTP transport - No API keys required for local stdio use — the server is a pass-through to public upstream endpoints ### Clone + build ```bash git clone https://github.com/cryptomotifs/cipher-x402-mcp cd cipher-x402-mcp npm install npm run build npm run smoke # tool-registry smoke test npm start # stdio transport npm run start:http # HTTP transport on :8080 ``` ### Configure your own upstream endpoints (optional) 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: ```bash CIPHER_SCAN_API_URL=https://your-scan.example.com \ CIPHER_PWNED_URL=https://your-pwned.example.com \ CIPHER_JITO_TIP_URL=https://your-jito.example.com \ CIPHER_REPO_HEALTH_URL=https://your-repo-health.example.com \ CIPHER_FRED_URL=https://your-fred.example.com \ CIPHER_DRIFT_URL=https://your-drift.example.com \ CIPHER_X402_URL=https://your-x402.example.com \ npx cipher-x402-mcp ``` ### Deploy to Vercel ```bash vercel link vercel --prod ``` The `/mcp` route serves MCP JSON-RPC messages; `/` serves a lightweight JSON manifest used by registries. --- ## 🛒 Buy A few small paid sidecars if the MCP is useful and you want to go deeper — all direct-pay, no platform middleman: - **[cipher-checkout.vercel.app](https://cipher-checkout.vercel.app/)** — three products, pay by card (Stripe) or crypto (Base USDC, Solana USDC, BTC): - **[x402 Paid Endpoint Starter Kit](https://buy.stripe.com/9B6cN55SlfXJ4Af9Nu2Ry09) — $19** — Next.js 16 starter repo + 7-page tutorial PDF + one-command Vercel deploy.
