# Environment Dependencies
Environment dependencies are used to **manage the binary tools and runtimes required for some advanced features of Cherry Studio**. For example, [MCP services](/docs/en-us/advanced-basic/extensions/mcp.md),[skills](/docs/en-us/advanced-basic/extensions/skills.md),[Agent](/docs/en-us/cherry-studio/preview/agent.md) some capabilities rely on underlying calls to `uv`,`bun` and other command-line tools. Cherry Studio centralizes them here so you don't have to manually install and configure them from the command line.
After opening `Settings → Environment Dependencies`:
Environment Dependencies: Built-in and Installable Tools
### Built-in and Installable
Each tool is shown as a card and labeled with a status:
* Marked with **Built-in** tools are distributed with Cherry Studio and work out of the box, with no action required.
* Uninstalled tool cards will show **Install** button, which Cherry Studio can click to automatically download and install into the app directory without affecting your system environment.
* The cards provide links to the source repository, official documentation, and an entry to open the local installation directory.
Common tools at a glance:
| Tools | Effect |
| ---------------- | ------------------------------------------------------------------------------------------------- |
| **uv** | A Python package management tool used for MCP services and dependency installation |
| **Bun** | A JavaScript runtime used by MCP services and related toolchains |
| **fd** | A fast file-finding tool,`find` an alternative to |
| **ripgrep (rg)** | A fast text search tool,`grep` an alternative to |
| **RTK** | A CLI proxy tool that compresses terminal output and reduces LLM token usage |
| **Lark CLI** | Feishu's official CLI, covering 200+ commands for messages / docs / spreadsheets / calendar, etc. |
The page also lists cards for `gh`(GitHub CLI),`ntn`(Notion CLI),`pi` and other tools, which can be installed with one click as needed. (Programming CLIs such as Claude Code / Codex are managed in [Coding companion](/docs/en-us/cherry-studio/preview/code-cli.md) the page, not on this page.)
### Add Tool
The “**Add Tool**” in the upper-right corner of the page lets you add tools outside the built-in list using mise tool keys (for example, `github:sharkdp/fd`,`uv`,`bun`).
### Advanced Installation Settings
Click the settings icon in the upper-right corner to open “**Advanced Installation Settings**”, and fine-tune how tools are downloaded (all fields can be left blank to use defaults):
* **GitHub mirror**: add a proxy prefix to GitHub Release downloads (for example, `https://ghfast.top`), used when direct connections are unreliable.
* **GitHub token**: Increase the GitHub API rate limit when querying tools (stored in plain text locally).
* **npm mirror / pip index URL**: set mirrors for `npm:` / `pipx:` and similar tools (leave blank to automatically choose a mirror in mainland China).
* **Verify tool signatures**: verify the tool's Sigstore / SLSA signatures; usually keep this enabled.
{% hint style="info" %}
Ordinary users generally don't need to do anything here—when a tool is needed, the relevant feature (such as installing an MCP service) will usually guide you back here for one-click installation. This page is more like an entry point for “checking and completing the runtime environment.”
{% endhint %}
{% hint style="warning" %}
If an MCP service or skill reports an error like “cannot find uv / bun / command not found,” first come here to confirm whether the corresponding tool is installed or marked as “Built-in” (the installation status refreshes automatically; the button in the upper-right corner is **Check for updates**, used to fetch the latest version of the tools).
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.cherryai.com.cn/docs/en-us/pre-basic/settings/env-dependencies.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
