agent_web_reader
Paid (x402, $0.002 USDC on Base). Fetch any http(s) URL and return clean readable text, title/description/canonical, and outbound links as JSON — the data an agent ingests on each step of a crawl/RAG loop.
LABSCO SUMMARY
Three tools that charge cents per call instead of asking who you are.
The trade is explicit: no account, no key and no rate-limit form, but every call needs a payment the agent settles itself, and until it does the tool returns a 402 challenge rather than data. That is worth it when the alternative is signing up for three separate APIs to answer one question.
What it is
A stdio server that bridges your client to the hosted Agent Web Reader service, where each of three tools is paid per call in USDC on Base through x402.
What you get
- Clean readable text for any http(s) URL, with title, description, canonical and outbound links as JSON, at $0.002 USDC per call (agent_web_reader)
- Price, market cap, 24h change and volume for CoinGecko ids, plus a momentum score from -100 to 100, a bullish, neutral or bearish signal and a volatility flag, at $0.005 USDC per call (crypto_market_signal)
- A 0 to 100 discoverability score for a GitHub repo's README, description, topics, homepage and metadata, with concrete fixes, at $0.005 USDC per call (github_repo_seo_audit)
- No API key and no signup: payment settles per call from the agent's own wallet
Requirements
npx, and a wallet that can pay x402 in USDC on Base mainnet. An unpaid call returns the 402 challenge; you pass the base64 X-PAYMENT value back as the x402_payment argument to settle it. One environment variable lets you point it at a different upstream service.
Setup effort
One command — npx -y github:charlie-morrison/agent-web-reader-mcp
USE CASES
01
Reading a page into an agent's context without an API key
Fetch the URL and get readable text plus title, description, canonical and outbound links as JSON.
02
Getting a quick read on a coin's momentum
Pull price and volume with the derived momentum score and volatility flag in one call.
03
Finding out why a repository gets no attention
Score the README, topics and metadata and take the concrete fixes it returns.
04
Letting an autonomous agent pay for its own data
Let it settle each 402 challenge from its wallet instead of provisioning keys ahead of time.
3 tools
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
crypto_market_signal
Paid (x402, $0.005 USDC on Base). For each CoinGecko id return price, market cap, 24h change, 24h volume, plus a derived momentum score (-100..100), a bullish/neutral/bearish signal, and a volatility flag — enriched data an agent ingests in a trading/research loop.
github_repo_seo_audit
Paid (x402, $0.005 USDC on Base). Score a GitHub repo's README, description, topics, homepage and metadata and return a 0-100 score, a grade, and concrete fixes. Input: owner, repo.
