cnvs.app MCP MCP server

A real-time collaborative whiteboard server that allows AI agents to read and edit boards alongside humans. It supports creating boards, adding text, images, links, and strokes, as well as managing kanban tasks. The server offers a hybrid loop using MCP for real-time subscriptions and REST for writes, with features like board locking and author attribution.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http cnvs-app-mcp https://cnvs.app/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add cnvs-app-mcp --url https://cnvs.app/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable cnvs-app-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "cnvs-app-mcp": {
      "url": "https://cnvs.app/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "cnvs-app-mcp": {
      "type": "streamableHttp",
      "url": "https://cnvs.app/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start cnvs-app-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "cnvs-app-mcp": {
      "type": "http",
      "url": "https://cnvs.app/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http cnvs-app-mcp https://cnvs.app/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "cnvs-app-mcp": {
      "url": "https://cnvs.app/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "cnvs-app-mcp": {
      "serverUrl": "https://cnvs.app/mcp"
    }
  }
}
