FyAgent puts your AI tool setup in one desktop app
FyAgent gathers models, skills, prompts and MCP services in one desktop app for Windows and macOS. Its license is PolyForm Noncommercial 1.0.0.
Illustration: a tidy desk where sorted little boxes ring a closed laptop — the arrangement FyAgent proposes for settings that are otherwise scattered across tools.
FyAgent is a locally installed desktop application that manages model settings, skills, prompts and MCP services for several AI tools from a single place, and every detail available so far comes from the project's own page.
At a glance
- License: PolyForm Noncommercial 1.0.0, which does not broadly permit commercial use.
- Platforms: installers for Windows and macOS; Linux is not listed on the project page.
- Stack per the project page: Rust with the Tauri framework, TypeScript interface built with Vite and Tailwind CSS.
- Snapshot at retrieval: 799 stars, 106 forks, 2,714 commits on the main branch.
- Unverified: no second account of the project exists independently of its maintainers.
FyAgent is a locally installed desktop application that manages model settings, skills, prompts and MCP services for several AI tools from a single place. The project frames itself as a portable working identity that travels with you between tools. Everything in this article comes from the project's own page; no independent review of it exists.
The problem it targets
Running several AI tools side by side means maintaining the same things repeatedly: provider credentials, model choices, system prompts, connected services. Each application keeps its own configuration format, so switching tools restarts the setup work. FyAgent aims at that duplication by collecting those settings behind one interface.
The design is deliberately local. The application runs on your own machine and reads the configuration of installed tools rather than moving it into a hosted service. Whether that scanning works reliably in practice cannot be judged from the project page alone.
What the page says it does
Five areas are described: managing models and providers with a preview step before saving, installing and assigning skills, adding MCP services, maintaining prompts across multiple tools, and editing long-term memory files for programs that keep them.
Among the supported programs, the page names Claude Code, Codex and OpenCode. The complete roster could not be read reliably: two retrievals of the same page returned lists of different length. This article therefore names only the entries that matched across both readings.
Stack and license
The project cites Rust with the Tauri framework underneath, plus a TypeScript interface built with Vite and Tailwind CSS, and testing through Playwright and Vitest. Prebuilt installers cover Windows and macOS; Linux does not appear in the list.
For workplace use, the license matters most. New components ship under PolyForm Noncommercial 1.0.0. The source is readable, but commercial use is not granted across the board. Teams considering the tool need to read those terms rather than treat it as a conventional open-source project.
What stays open
The page's counters — 799 stars, 106 forks, 2,714 commits on the main branch — are a snapshot taken at retrieval and say nothing about how many people actually run the tool. No release version number or publication date was visible on the page that was read.
The security picture is the biggest gap. An application that reads and writes the configuration files of multiple AI tools inevitably sits close to stored API credentials. How FyAgent handles that is not stated on the project page, and no independent analysis of it is available. Documentation is offered in Chinese, English and Japanese, and the project describes itself as still under active development.
FAQ
What is FyAgent?
A locally installed desktop application that manages model settings, skills, prompts and MCP services for several AI tools through one shared interface.
Can companies use FyAgent for free?
Not without checking first. New components are licensed under PolyForm Noncommercial 1.0.0, which restricts commercial use. The license text governs, not this summary.
Does FyAgent run on Linux?
The project page lists installers for Windows and macOS only. Linux is not mentioned there, so whether it works unofficially is left unanswered.
