install

install is a command for coding agents from DaveDev42/expo-mcp. It costs 45 tokens per session (1,546 once invoked), scanned B, original, no licence file.

A one-step installer for expo-mcp, a tool that connects an Expo app to an MCP server. It checks prerequisites, finds the app folder, updates Claude Code settings, and asks you to restart.

In plain words
What is it for?
Use it to add expo-mcp to an existing Expo project and prepare it for use with Claude Code.
Why use it?
It removes the need to find the right Expo directory or edit Claude Code’s settings by hand. It also avoids setting up the connection through a plugin interface.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add commands/davedev42/expo-mcp/install
Clone the repo
git clone --depth 1 https://github.com/DaveDev42/expo-mcp

Or install expo-mcp, the plugin that ships this one along with the rest of its 1 skill, 1 command, 2 agents, 1 hook, 1 MCP server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

install scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- **`--global`** — write plugin userConfig to `~/.claude/settings.json` instead of the project-local `.claude/settings.json`. Default: project-local.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
