Overboard Studio Server

Overboard Studio is a collaborative whiteboard. This is the official Model Context Protocol (MCP) server: it lets any AI agent (Claude, ChatGPT, Cursor, Codex, …) create and manage real, shareable boards — sticky notes, shapes, text, frames, charts, flowcharts, tables, connectors — that show up live in the Overboard web app.

Hosted endpoint (recommended): https://overboard.studio/mcp (OAuth, supports Claude.ai, ChatGPT, Cursor, etc.)

Stdio mode: for Claude Code / Cursor / Claude Desktop running locally.

Quick connect

Claude.ai (web)

Settings → Connectors → Add custom connector → URL: https://overboard.studio/mcp → complete the OAuth flow.

Claude Code

claude mcp add --transport http overboard https://overboard.studio/mcp
/mcp auth

Claude Desktop (stdio)

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "overboard": {
      "command": "npx",
      "args": ["-y", "@overboard/mcp-server"],
      "env": {
        "SUPABASE_URL": "https://your-project.supabase.co",
        "SUPABASE_SERVICE_ROLE_KEY": "your-service-role-key"
      }
    }
  }
}

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "overboard": {
      "url": "https://overboard.studio/mcp"
    }
  }
}

Tools (16)

Boards

Tool	Description	Annotation
get_current_user	Authenticated user's id, email, display name	read-only
list_boards	Boards you own or were invited to	read-only
get_board	Board metadata + member/element counts	read-only
create_board	New empty board, you become owner	write
create_board_with_elements	New board pre-populated with elements (preferred)	write
rename_board	Rename a board you own	write, idempotent
delete_board	Cascade-delete board, members, elements	destructive
get_board_url	Direct URL to open board in the web app	read-only

Elements

Tool	Description	Annotation
get_elements	All elements on a board	read-only
create_element	Add sticky note / shape / text / frame / chart / etc.	write
bulk_create_elements	Batch create (preferred for >2 elements)	write
update_element	Merge properties — move/resize/recolor/edit text	write, idempotent
delete_element	Remove a single element	destructive

Collaboration

Tool	Description	Annotation
get_collaborators	Members of a board with roles	read-only
get_board_activity	Recent element changes (default last 24h)	read-only
invite_to_board	Generate a shareable invitation link	write

Element types

sticky-note, text, path, shape, connector, frame, graph, chart, flowchart, table, timeline, kanban, doc, vote, timer, estimation

Smart defaults are applied for position, size, and styling — you only need to specify what you want to customize.

Authentication

The hosted endpoint uses OAuth 2.0. The client (Claude.ai, etc.) walks the user through Overboard's auth flow once; tokens are valid for 30 days.

Stdio mode uses the Supabase service-role key — pass it as an env var. Each tool call enforces per-user board access via Supabase Row-Level Security; the service-role key only bypasses RLS for the tools that need to read/write multi-user state.

Build from source

npm install
npm run build
node dist/index.js

For HTTP mode:

node dist/index.js --http --port=3002

Test with MCP Inspector

SUPABASE_URL=... SUPABASE_SERVICE_ROLE_KEY=... \
  npx @modelcontextprotocol/inspector node dist/index.js

Example prompts

Once connected, try:

• "List all my boards"
• "Create a sprint planning board with 5 yellow sticky notes for: Design login, Set up API, Write tests, Deploy staging, Code review"
• "Show me everything on board {id}"
• "Move the first sticky note to (500, 300) and recolor it green"
• "Generate an invite link for board {id} as editor"
