MCP support
The MCP server at `https://capxule.ai/mcp` exposes journey discovery, browsing, step progression, progress state, artifacts and account linking. It supports Streamable HTTP without authentication; journey content remains on Capxule rather than being sent to the assistant in bulk.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Details
From the project READMECapxule
The context marketplace. People who know a topic package what they know into guided journeys, and your AI assistant walks you through them one step at a time. Rent or buy, prepare for the U.S. citizenship civics test, calm a child through a meltdown, dispute a medical bill, start strength training after fifty, and much more across money, health, career, family and learning.
Connect your assistant to https://capxule.ai/mcp and it can find the right journey and guide you through it in the chat.
- A step at a time, with choices. Every step comes with numbered options, so you choose the direction. Ask in your own words at any point and the journey adapts.
- Practice and progress. Practice journeys quiz you and track what you missed. Ask "where am I?" to see how far you have come and what is left, by topic.
- Pick up anywhere. Stop whenever you like and continue later, even in another assistant, with a resume link.
- No sign-in to connect. When you want to keep your progress, the assistant can connect a Capxule account right in the chat with a code sent to your email. No password, no site visit.
The full list of journeys is in CATALOG.md (live versions: capxule.ai/catalog and capxule.ai/catalog.jsonl).

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
