Best practices for using Radon IDE's MCP tools when developing, debugging, and inspecting React Native and Expo apps.

  • Interacting with a running app through Radon IDE - viewing screenshots
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Inspecting the component tree
  • Debugging network requests

What it does

Radon MCP is an agent skill from software-mansion-labs/skills. Best practices for using Radon IDE's MCP tools when developing, debugging, and inspecting React Native and Expo apps. Use when interacting with a running app through Radon IDE - viewing screenshots, reading logs, inspecting the component tree, debugging network requests, reloading the app, or querying React Native documentation and library info. Trigger on: 'debug React Native', 'fix UI', 'network issues', 'build issues', 'Radon IDE', 'view screenshot', 'app logs', 'component tree', 'network inspector', 'reload…

Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including reference files (for example `references/get-library-description.md`, `references/query-documentation.md` and `references/reload-application.md`).

It sits in Mobile, covering Cross-platform mobile apps, MCP servers and Debugging. It works with React Native, Model Context Protocol and Expo. The repository describes itself as: Software Mansion's set of skills for AI-assisted React Native development.

When your agent uses it

  • Interacting with a running app through Radon IDE - viewing screenshots
  • Inspecting the component tree
  • Debugging network requests
  • Reloading the app

Example prompts

  • “debug React Native”
  • “fix UI”
  • “network issues”
  • “/radon-mcp”

What it can do on your machine

Read from SKILL.md and the folder at commit e3f00cd. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Radon MCP loads about 665 tokens when it runs, and up to ~4.2k if it reads all its reference files. Until then it costs about 226 tokens; SKILL.md has 145 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~226
When it runs · the whole SKILL.md, loaded when a task matches
~665
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 145 words (~665 tokens).

“Best practices for Radon IDE's MCP tools for live React Native / Expo app inspection and debugging.”
