mila

Create, read, update, and delete documents, spreadsheets, and slide presentations in Mila via the REST API or MCP tools. Use when the user wants to manage collaborative documents with rich HTML content, workbooks with tabs and cells in A1 notation, or slide decks with free-form HTML on a 960x540 canvas. Supports pagination, server-based organization, real-time collaboration, formulas, cell formatting, speaker notes, and themes.

Mila is a collaborative platform for documents, spreadsheets, and slide presentations. This skill teaches you how to interact with Mila's REST API and MCP tools to manage content programmatically.

Get started at https://mila.gg -- create an account, generate an API key, and start building.

Authentication

All requests require a Mila API key. Keys use the format mila_sk_*.

• Create individual keys at mila.gg/api-keys
• Create team keys at mila.gg/team-api

API keys have scopes that control access (e.g. documents:read, documents:write, sheets:read, sheets:write, slides:read, slides:write).

REST API authentication

Include the API key as a Bearer token:

Authorization: Bearer mila_sk_your_key_here

Base URL: https://api.mila.gg/v1

MCP authentication

The MCP server uses the same API keys. Include the key in the Authorization header when connecting to the MCP endpoint.

MCP endpoint: https://mcp.mila.gg

MCP setup

If the user wants to connect Mila to an AI client via MCP, use these configurations:

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "mila": {
      "url": "https://mcp.mila.gg",
      "headers": {
        "Authorization": "Bearer mila_sk_your_key_here"
      }
    }
  }
}

Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "mila": {
      "url": "https://mcp.mila.gg",
      "headers": {
        "Authorization": "Bearer mila_sk_your_key_here"
      }
    }
  }
}

VS Code Copilot (.vscode/mcp.json):

{
  "servers": {
    "mila": {
      "type": "http",
      "url": "https://mcp.mila.gg",
      "headers": {
        "Authorization": "Bearer mila_sk_your_key_here"
      }
    }
  }
}

Quick start

Create a document

curl -X POST https://api.mila.gg/v1/documents \
  -H "Authorization: Bearer mila_sk_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{"title": "Meeting Notes", "content": "<h1>Meeting Notes</h1><p>Discussed roadmap.</p>"}'

MCP tool: create_document with title and content (HTML string).

Create a spreadsheet

curl -X POST https://api.mila.gg/v1/sheets \
  -H "Authorization: Bearer mila_sk_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{"title": "Budget", "cells": {"A1": {"value": "Item"}, "B1": {"value": "Cost"}, "A2": {"value": "Hosting"}, "B2": {"value": 99}}}'

MCP tool: create_sheet with title and cells (A1 notation object).

Create a presentation

curl -X POST https://api.mila.gg/v1/slides \
  -H "Authorization: Bearer mila_sk_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{"title": "Demo", "data": [{"html": "<div style=\"display:flex;align-items:center;justify-content:center;height:100%\"><h1 style=\"font-size:48px\">Hello</h1></div>", "background": "#ffffff", "notes": "Title slide"}]}'

MCP tool: create_slide_presentation with title and data (array of slide objects).

API conventions

IDs

All resource IDs are opaque strings (e.g. "xK9mP2wQ"). Use them as-is in URLs and parameters.

Pagination

List endpoints accept limit (1-100, default 50) and offset (default 0). Responses include a pagination object:

{
  "data": [...],
  "pagination": { "total": 42, "limit": 50, "offset": 0 }
}

Sorting

List endpoints accept sort (created_at, updated_at, last_edited_at, title) and order (asc, desc).

Server filtering

Content can belong to a server (workspace) or to personal files.

• Omit server_id: returns all content
• server_id=personal: returns only personal files
• server_id=<id>: returns content in that server

Pass server_id in the request body when creating content to place it in a server. Omit for personal files.

Response format

All responses use this structure:

{
  "success": true,
  "data": { ... }
}

Errors return:

{
  "success": false,
  "error": { "message": "Description of the error" }
}

Content formats

• Documents: HTML strings (headings, paragraphs, lists, tables, images, links). <script> tags are stripped.
• Sheets: Cell data in A1 notation (e.g. {"A1": {"value": "Name"}, "B1": {"value": 42}}). Formulas start with =.
• Slides: Free-form HTML on a 960x540px canvas. Each slide has html, background, and notes fields.
