Connect your MCP servers once. Use them in every AI client.
Nexus signs in to GitHub, Notion, Linear and any other remote MCP server for you, then serves them through Stars: MCP endpoints you add to Claude Code, claude.ai, Codex, Cursor and Grok. Decide what each client can do here, not in a pile of config files.
New here? Signing in creates your account.
Connect each server once
Pick a service from the gallery or enter any remote MCP server. Your credentials are encrypted with a key of your own.
Bundle them into Stars
A Star is one MCP endpoint with the Connections you choose. Clients reach it with a token, a signed URL or by signing in to Nexus.
Switch every tool on or off
Read-only tools start on and everything else starts off, so a new Star is safe. Change it per Star at any time.

Every tool call is recorded with its time, status and duration. Arguments and results are never stored.
