## What ax402 does, in the publisher's words

Agent plugin for the Ax402 platform. Bundles @ax402/mcp-server (stdio via npx) plus skills and slash commands.

One package, four clients:

ChatGPT's public plugin directory wants a hosted Streamable HTTP MCP. This package is local stdio. Codex and ChatGPT desktop can still install it from this repo.

From the project README, punctuation lightly normalized. Full text: https://raw.githubusercontent.com/AxLabs/ax402-plugins/HEAD/plugins/ax402/README.md

## Skills

- ax402: Manage Ax402 seller APIs and x402 payments via MCP tools. Use when wrapping an upstream API, pricing endpoints, inspecting HTTP 402 Payment Required, listing settlements, or the user mentions Ax402 / x402 / paid APIs.
- setup: Configure the Ax402 plugin MCP server (API key, base URL, sandbox vs live). Use on first install, when tools fail with AX402_API_KEY required, or when switching Sandbox and production.

Descriptions come from the frontmatter of each SKILL.md, punctuation lightly normalized.

## MCP servers

- ax402: transport: stdio; command: npx -y @ax402/mcp-server
