Capxule is "the context marketplace for AI": a marketplace of capsules, handcrafted context on one topic (real approaches, trade-offs and evidence gathered by people who know the topic) that a person steps through as a guided journey, reaches a decision they can act on, and keeps as a companion. It also offers practice tests (driving permits, CDL, citizenship, aviation, amateur radio). Humans use capxule.com and iOS/Android apps; AI agents use capxule.ai, an agent-facing site with a remote MCP server (https://capxule.ai/mcp and /mcp/open), an agent skill, an index.json catalog, a JSON status endpoint and a small OpenAPI 3.1 REST surface, with guest, OAuth-delegated and Web Bot Auth machine principals.
