Usage of Remote Server

Prerequisites

An MCP host that supports the latest MCP specification and remote servers, such as Claude, VS Code and Cursor.

Installation

Claude Desktop or Web UI

Search and tools -> Add integrations -> Add integration -> Set Integration name to the name of your choice (e.g., mostlyai) and Integration URL to https://mcp.mostly.ai/sse.

VS Code (>= v1.101)

For quick installation, please use the one-click button above. Alternatively, one can add the following JSON to .vscode/mcp.json (for the workspace) or the global settings.json (for the user).

{
  "servers": {
    "mostlyai": {
      "url": "https://mcp.mostly.ai/sse"
    }
  }
}

Cursor

For quick installation, please use the one-click button above. Alternatively, one can add the following JSON to ~/.cursor/mcp.json.

{
    "mcpServers": {
      "mostlyai": {
        "url": "https://mcp.mostly.ai/sse"
      }
    }
}

Development

Setup virtual environment

uv sync --frozen

Start the server locally

Set the necessary environment variables (see .env.example)
uv run mostlyai-mcp-server --port 8000
Connect to the server with the configuration described in the above section, but change the url to http://localhost:8000/sse.

Debug
