A Model Context Protocol server that exposes the canonical Reaction Time Test knowledge surface — browser tests, measurement rules, and score interpretation, FAQ, official links — to MCP-compatible AI clients such as Claude Desktop, Cursor, Windsurf, and Continue. Read-only, no API keys, no quota, ~50 ms cold start.

## ⏱️ About Reaction Time Test
Reaction Time Test is a free browser test built around five rounds of waiting for green and tapping as quickly as possible. It reports average milliseconds, rank context, a daily streak, and a shareable result card without requiring an account.
The site also offers click speed, aim, memory, number memory, and typing tests. Scores and streaks stay in browser localStorage, and the application has no server endpoint for test results. This MCP explains the test catalog and measurement rules as read-only context; it cannot run a test or measure the user's reflexes.
Use the live test for an actual result. A browser reaction score is a lightweight game metric, not a medical diagnosis or a guarantee of performance in another setting.
## Tools
### `get_test_overview`
Return the test catalog and documented measurement or scoring rules exposed by the site. (Reaction Time Test)
_Input:_ no parameters. _Returns:_ text/markdown.
### `get_official_links`

## Installation
### Install via Smithery
```bash
npx -y @smithery/cli install reactiontimetest-mcp --client claude
```
(Replace `claude` with `cursor`, `windsurf`, or `continue` for those clients.)
### Install from source
```bash
git clone https://github.com/rocnubie/reactiontimetest-mcp.git
cd reactiontimetest-mcp
pnpm install
```
Then add to your MCP client config (`claude_desktop_config.json` for Claude Desktop, `mcp.json` for Cursor / Windsurf / Continue):
```json
{
"mcpServers": {
"reactiontimetest-mcp": {
"command": "node",
"args": [
"/absolute/path/to/reactiontimetest-mcp/src/index.mjs"
]
}
}
