Maias tools (5)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • edit

    Reference-safe edits: rename_screen cascades to flows, the navigation registry, and every target; add_screen registers the screen; remove_screen refuses to leave dangling references unless cascade is set. Writes the result back to the file (canonically formatted when format_output is true).

  • edit_elements

    Batch edit of a screen's `elements` list (or a declared state's list): insert, update, remove, move.

  • query

    Graph utilities over a MAIAS file: get one screen, list screens/flows, reachability analysis, orphan detection, "what links here" for a screen id, a text outline of the structure (tree — show this to the user after creating or restructuring a document), and a Mermaid flowchart (mermaid — renders in GitHub/Claude/Obsidian). tree and mermaid return plain text, not JSON; mermaid accepts an optional f

  • validate

    JSON Schema validation plus semantic lint (dangling targets, orphans, registry membership, …) for a MAIAS file. Returns { valid, diagnostics[] } with line/col positions.

  • wireframe

    Deterministic mobile wireframes from a MAIAS file: one self-contained HTML file (inline CSS, no JS, no external URLs) with one phone frame per screen, flows as rows, and click-through anchors between frames. Pass out to write the file (recommended — returns a summary); without out the raw HTML is returned as text (large). Refuses documents with validation errors (dangling targets become dead links

Install Maias in Claude Code, Cursor or VS Code

Runs npx -y @maias/mcp on your machine. Read the scan report first; the gateway never runs local packages.

MAIAS — Mobile App Information Architecture Schema

An open standard for describing an app's information architecture — screens, navigation, flows, UI elements, states, and data dependencies — in one YAML (or JSON) document that is equally readable by humans and operable by agents.

maias: "0.3"
app:
  name: Todo List
  navigation:
    primary:
      screens: [home, settings]     # ← the tab bar, derived, not drawn
  flows:
    - name: main
      entry_screen: home
      screens: [home, task_detail, task_new]
screens:
  - id: home
    title: My Tasks
    type: list
    path: /tasks
    description: All tasks, newest first.
    elements:
      - label: Buy milk
        type: list_item
        target: task_detail          # ← references are validated, renames cascade

Why: a common language for human–agent collaboration on app development. An agent can build the described app from the document (implementation guide), create and edit documents as safe machine operations (CLI, MCP), and a human can read and review the same file.

What's in this repo

Quick start

Requires Node.js 20.19.4+ / 22.13+ / 24.3+ (CI runs 22). No clone or install needed — the packages are on npm:

# validate a document — schema + semantic lint (dangling targets, orphans,
# path collisions), with line numbers; add --json for machine-readable output
npx -y @maias/cli validate my-app.maias.yaml

# canonical formatting (idempotent; agent edits diff cleanly)
npx -y @maias/cli fmt my-app.maias.yaml --write

# rename a screen — cascades to flows, navigation, every target
npx -y @maias/cli rename my-app.maias.yaml old_screen new_screen

Prefer a plain maias command? npm i -g @maias/cli.

In Claude Code, one install delivers the three skills plus the MCP server:

/plugin marketplace add MAIAS-project/maias-plugin
/plugin install maias@maias

In any MCP client, add the server with claude mcp add maias -- npx -y @maias/mcp (or the JSON equivalent — see packages/mcp); it is also listed in the official MCP registry as io.github.MAIAS-project/maias.

The MAIAS Browser (render any document as a working app, web/iOS/Android) runs from a clone:

git clone https://github.com/MAIAS-project/maias.git && cd maias
npm install && npm run build
npx maias validate examples/todo_list/maias.yaml
npm run web --workspace maias-browser

Shortened. The full README is on GitHub.
