Build and Connect Your First MCP Server in a Day — No Guesswork, No Stack Overflow

The problem: The MCP documentation is technical and scattered. Building your first server from scratch requires connecting concepts that aren't explained together anywhere: the protocol, the tools, the authentication, and the payment layer. Most people get stuck at the same three points.

The solution: Four frameworks that take you from zero to a working MCP server — including the A2A commerce layer for agent-to-agent payments and the wallet setup you need to actually transact.

What you get (4 SKILL.md frameworks):

• MCP Server From Scratch — step-by-step build guide with real code patterns
• MCP Tools Explained — the tool specification format, input validation, and response patterns
• A2A Protocol Explained — agent-to-agent commerce: how the protocol works, how to wire it
• Agent Wallet Setup — Base network wallet configuration, USDC, and signing setup

Who it's for: Developers and OpenClaw operators who want to build and monetise their own MCP server — and want a day-one working result, not a multi-week exploration.

Time to value: One day from zero to a working server.
