Capxule MCP Server

About Capxule

Capxule is the context marketplace: expert-curated capsules you take as guided AI journeys, then keep as companions. Connect Capxule's hosted MCP server to Claude, ChatGPT (where your plan allows), Claude Code, or any MCP client. No sign-in is required to start; the first answers on each journey are free.

Capxule tools (9)

Read from the live server on Nov 8, 2026. These are the tools your AI assistant can call once connected.

find_journey

Use when the user wants a guided, step-by-step journey on a topic, a skill or an exam. Searches the published journeys and returns up to three cards (id, title, summary, shape, languages, number of stops, estimated minutes, who it is for an

list_journey_categories

Use when the user asks what kinds of journeys are available. Returns each category slug, a readable label, the number of journeys in it and a few example titles.

browse_journeys

Use when the user wants to look through the journeys, optionally within one category (a slug from list_journey_categories). Returns a page of the same cards as find_journey, with the total and next_offset.

open_journey

Use when the user chooses a journey to start or continue. Opens it, or resumes the user's session for it, and returns the session contract: `session`, the stop titles, the capabilities, the limits in turns and the first step. Calling it aga

take_journey_step

Use for every step after open_journey. Sends the user's choice and returns the next step: `answer`, `statement`, numbered `options` with ids, `media`, `progress` and `limits`. Send `pick` with an option id when the user chose an option or i

get_journey_progress

Use when the user asks where they are in a journey, how far they have come or how much is left. Returns the current stop, visited and remaining stops, percent done, practice stats, limits and a resume line.

create_takeaway

Use when the user asks for a summary to keep. Composes a markdown takeaway from this journey session: what the user asked, the key points and the stops visited. Available on connected accounts; otherwise returns not_available.

get_resume_link

Use when the user wants to continue the journey later, on the website or in another assistant. Returns a resume link and a short resume code for this session.

restart_journey

Use only when the user explicitly asks to start a journey over, after confirming with them. Returns to the first step and clears the visited stops; turns already used stay used. Returns the same session contract as open_journey.

How to connect Capxule to Claude, Cursor or VS Code

Capxule runs as a hosted remote MCP server at https://capxule.ai/mcp. Add that URL to your MCP client's config (Claude Code, Cursor, Windsurf or VS Code) and the tools appear immediately, no install required.

  "mcpServers": {
    "capxule": {
      "url": "https://capxule.ai/mcp"
    }
  }
}

Claude Code: claude mcp add --transport http capxule https://capxule.ai/mcp. VS Code's .vscode/mcp.json uses a servers key instead of mcpServers (see how). Servers that require OAuth or an API key will prompt on first use.
