agent-web-reader-mcp

A tiny stdio MCP server that bridges any MCP client (Claude Desktop, Cursor, Cline, …) to the hosted Agent Web Reader x402 service. Three pay-per-call tools for AI agents — no API key, no signup. Payment is x402 / USDC on Base, settled per call from the agent's own wallet.

Tools

• `crypto_market_signal` — price, market cap, 24h change/volume + a derived momentum score (−100..100), bullish/neutral/bearish signal and volatility flag for any CoinGecko ids. *$0.005 USDC.*
• `agent_web_reader` — clean readable text + title/description/canonical and outbound links as JSON for a URL — the data an agent ingests each crawl/RAG step. *$0.002 USDC.*
• `github_repo_seo_audit` — 0–100 discoverability score for a GitHub repo + concrete fixes. *$0.005 USDC.*

Use

Install straight from GitHub — no npm account needed, nothing to clone:

// Claude Desktop / Cursor / Cline MCP config
{
  "mcpServers": {
    "agent-web-reader": {
      "command": "npx",
      "args": ["-y", "github:charlie-morrison/agent-web-reader-mcp"]
    }
  }
}

Or run directly:

npx -y github:charlie-morrison/agent-web-reader-mcp

> The `agent-web-reader-mcp` name on the public npm registry is reserved for the

> same package; until that listing is live, the `github:` spec above is the

> canonical install and pins to `master`.

Without payment each tool returns the x402 402 challenge (scheme `exact`, USDC on Base mainnet). Supply the base64 `X-PAYMENT` header value as the `x402_payment` argument to settle and get the result.

Override the upstream with `AGENT_WEB_READER_URL` (default `https://x402.charliemorrison.dev/mcp`).
