Nexus Mcp

Overview

Nexus Mcp is a Model Context Protocol server that lets you invoke CLI agents like Codex, Claude, and OpenCode as callable MCP tools with parallel execution support. Instead of switching between applications and copying output manually, your AI assistant can use these agents directly as integrated tools.

The server runs locally on your machine via the uvx package manager using the command uvx nexus-mcp. It communicates with MCP clients over stdio and requires no authentication or credentials to get started. Version v1.0.3 is available now under the MIT license, with full source code hosted at j7an/nexus-mcp on GitHub.

Nexus Mcp is listed in the Development category on mcp.site and works with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this project, you can claim this listing to verify ownership, display a Verified badge, and keep the information up to date.
