Clean web reader for AI agents. Pays $0.002/call in USDC on Base via x402. No API keys.
Most developer tooling work still happens through a UI a human drives. Skim402 MCP server moves it into the conversation instead. Clean web reader for AI agents. Pays $0.002/call in USDC on Base via x402. No API keys.
A dollar funds roughly 500 reads. Full step-by-step (with screenshots, for non-crypto-native devs): https://skim402.com/wallet.
The server publishes 7 tools. What each one is for:
GitHub — https://github.com/JessieJanie/skim402Variable — RequiredSKIM_WALLET_PRIVATE_KEY — yesSKIM_MAX_PRICE_USD — noSKIM_API_URL — noSKIM_TIMEOUT_MS — noread_url — Reads any URL and returns clean Markdown with a YAML frontmatter blockInstallation goes through your MCP client rather than a global install: point it at skim-mcp on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Configuration is passed through the environment: SKIM_WALLET_PRIVATE_KEY, SKIM_API_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Skim402's toolset — GitHub, Variable, SKIM_WALLET_PRIVATE_KEY and 4 more — is a fair guide to whether it matches your workflow. It is maintained by JessieJanie; worth a glance at recent repository activity before you build anything load-bearing on it.
