# mcpx

> mcpx — supermarioyl-mcpx. Use this tool when you need to manage stdio MCP entries across multiple client configurations, solving issues with configuration inconsistencies and data loss. It takes JSON and TOML client configs as input and produces merged configurations with backups, while also performing a server handshake smoke test. Ideal for use cases involving configuration management and testing, especially in git-based workflows.

## Description

One-command MCP-server installer for every coding-agent client (Claude Code, Cursor, Codex): detect, backup, idempotent write, handshake smoke test. v0.6.0 hardens input handling (catalog --args now errors, --clients ids validated) and runs one handshake per add instead of one per client.
