"Managing MCP servers is a config file nightmare. Every AI client stores them differently, and you're editing raw JSON across a dozen different paths — hoping you don't break something."

✕Scattered JSON files across ~/Library, ~/.cursor, ~/.codeium…
✕No single view of what's installed where
✕One typo silently breaks every tool in a client
How it works

Three steps to clarity

From chaos to control in under a minute.

01

Detect

mTarsier automatically scans your machine for every AI client installed — Claude Desktop, Cursor, Windsurf, VS Code, and more. No configuration needed.

02

Manage

Edit MCP server configs for all clients in one unified interface. Built-in JSON validation catches errors before they break your tools.

03

Install

Browse the marketplace and install MCP servers into any client with a single click. No more copying JSON snippets between files.
