# Improved MCP Server

* **Sign in to the hosted MCP server**: add `https://mcp.captain.dev/mcp` to Claude Code, Cursor, VS Code or any client with remote MCP sign-in; a browser opens on Captain's approval page to pick the organization, the environments and whether the connection may write.
* **One connection, every environment**: every tool takes an optional `environment` (`development`, `staging` or `production`), so one session can search development and production without reconnecting.
* Client configs for Claude Code, Codex, Cursor, VS Code, Devin and others: [MCP Server](/guides/mcp).
