"Managing MCPs manually and skills across different places is a nightmare. mTarsier lets you — or your AI — manage all your MCPs and skills from one place."

✕MCP configs scattered across ~/Library, ~/.cursor, ~/.codeium…
✕Skills managed separately with no unified view
✕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 and skill configs for all clients in one unified interface. Built-in JSON validation catches errors before they break your tools.

03

Skills

Discover and install skills via search, import, or copy. View content and deploy to multiple clients at once for a consistent experience.

04

Install

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

The missing link

Your AI agent could be doing so much more.

The right MCP servers and skills unlock research, memory, coding, browsing, and automation. But finding and wiring them up is hard and chaotic. mTarsier fixes the whole chain.

✕Searching docs and Reddit to find a useful MCP server or skill
✓Browse a curated marketplace — install in one click
✕Hand-editing JSON scattered across ~/Library, ~/.cursor, ~/.codeium…
✓One unified editor for every client, with live validation
✕Finding out your config broke hours later — no error, no warning
✓Auto-backup before every change. Roll back in one click.
✕Sharing your MCP and skills setup with teammates means sending JSON files and hoping they get it right
✓Export a .tsr snapshot — teammates import it in one click, every client pre-configured
