  "markdown": "# navi-x402-mcp\n\nMCP server that gives your AI agent **paid superpowers with zero API keys**: live\ncrypto prices, weather + air quality, translation, AI market reports, web page\nintelligence, Google Sheets reading, URL previews — and `navi_x402_scout`, which\nfinds the best x402 service in the ecosystem for any task.\n\nEvery call is paid per-request in **USDC on Base** via the\n[x402 protocol](https://docs.cdp.coinbase.com/x402/welcome) (prices: $0.001–$0.02).\nNo accounts, no API keys, no subscriptions: your agent's wallet pays only for\nwhat it uses.\n\n## Setup\n\n1. Fund a wallet with a few USDC on **Base mainnet** (a dollar goes a long way).\n2. Add to your MCP client config (Claude Desktop, Cursor, etc.):\n\n```json\n{\n  \"mcpServers\": {\n    \"navi-x402\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"navi-x402-mcp\"],\n      \"env\": {\n        \"X402_PRIVATE_KEY\": \"0x<private key of the paying wallet>\",\n        \"MAX_PRICE_USDC\": \"0.05\"\n      }\n    }\n  }\n}\n```\n\n## Tools\n\nTools are generated dynamically from the live\n[Navi catalog](https://navi-x402-dashboard.vercel.app/catalog/navi) — new\nendpoints appear automatically. Current highlights:\n\n| Tool | What it does | Price |\n|---|---|---|\n| `navi_x402_scout` | Top-3 x402 services for a task, ranked by real 30-day usage | $0.005 |\n| `navi_crypto_prices` | Live prices, 7d/30d change, ATH context (CoinGecko) | $0.001 |\n| `navi_market_report` | Structured AI crypto market analysis | $0.02 |\n| `navi_weather` | Forecast + air quality for any location | $0.001 |\n| `navi_translate` | Translation with BCP-47 normalization + formality | $0.005 |\n| `navi_web_intelligence` | AI page analysis: summary, entities, sentiment | $0.005 |\n| `navi_page_context` | Page structure, link taxonomy, repo metadata | $0.005 |\n| `navi_google_sheets` | Read any shared Google Sheet as typed JSON | $0.003 |\n| `navi_url_preview` | OpenGraph/Twitter card metadata | $0.001 |\n| `navi_timestamp` | Timezone-aware time with DST/week signals | $0.001 |\n\n## Safety\n\n- `MAX_PRICE_USDC` (default `0.05`) hard-caps the per-call price the server\n  will ever authorize.\n- The private key never leaves your machine: it signs EIP-3009 transfer\n  authorizations locally; settlement happens on-chain via the Coinbase\n  facilitator.\n- Without `X402_PRIVATE_KEY`, tools are listed and explain how to enable\n  payments instead of failing silently.\n\n## Env reference\n\n| Var | Default | Purpose |\n|---|---|---|\n| `X402_PRIVATE_KEY` | — | Paying wallet (USDC on Base mainnet) |\n| `MAX_PRICE_USDC` | `0.05` | Per-call price ceiling |\n| `NAVI_CATALOG_URL` | Navi public catalog | Alternative catalog source |\n\nMIT — built by [Navi](https://navi-x402-dashboard.vercel.app/catalog/navi).\n",
