Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

AppMetrica MCP

MCP server for AppMetrica — Yandex's mobile analytics platform. Gives Claude direct access to your app's analytics: reports, raw event logs, crash data, and push notification campaigns.

Features

  • Reporting API — aggregated metrics (users, sessions, revenue, retention) with dimension breakdowns
  • Logs API — raw event, crash, and installation exports
  • Management API — list and inspect your AppMetrica applications
  • Push API — view campaigns and statistics; create campaigns when write mode is enabled
  • Safe by default — write operations are disabled unless you explicitly opt in

Requirements

  • Node.js 22+
  • An AppMetrica account with at least one application
  • A Yandex OAuth token (see below)

Getting an OAuth Token

AppMetrica uses Yandex OAuth. Use the Russian OAuth portal (oauth.yandex.ru) — the international version (oauth.yandex.com) does not expose AppMetrica scopes in its UI.

Step 1 — Create an OAuth app

  1. Go to oauth.yandex.ru/client/new
  2. Fill in any name (e.g. AppMetrica MCP)
  3. Under Platforms, select Web services and set the Callback URI to:
    https://oauth.yandex.ru/verification_code
  4. Under Доступы (Access), find the AppMetrica section and enable:
    • Чтение данных AppMetrica — read access (required)
    • Запись данных AppMetrica — write access (optional, needed for push campaign creation)
  5. Click Создать приложение and copy the ClientID

Step 2 — Get a token

Open this URL in your browser (replace CLIENT_ID with your app's ID):

https://oauth.yandex.ru/authorize?response_type=token&client_id=CLIENT_ID

Log in → authorize the app → copy the access_token value from the redirect URL.

Note: The token does not expire by default. You can revoke it anytime at passport.yandex.ru/profile/access.

Installation

Claude Code (recommended)

claude mcp add appmetrica \
  -e APPMETRICA_OAUTH_TOKEN=your_token \
  -- npx -y appmetrica-mcp

To enable write operations (push campaign creation):

claude mcp add appmetrica \
  -e APPMETRICA_OAUTH_TOKEN=your_token \
  -e APPMETRICA_ALLOW_WRITE=true \
  -- npx -y appmetrica-mcp

Claude Desktop

{
  "mcpServers": {
    "appmetrica": {
      "command": "npx",
      "args": ["-y", "appmetrica-mcp"],
      "env": {

      }

  • "Show DAU and sessions for app 12345 over the last 7 days"
  • "Export crash logs for app 12345 from 2024-01-01 to 2024-01-07"
  • "What push campaigns are currently active for app 12345?"
  • "Show me new user counts broken down by app version"

Rate Limits

AppMetrica enforces the following limits on all API requests:

  • 30 requests / second per OAuth token
  • 5,000 requests / day per OAuth token

The client retries automatically on 429 and 5xx responses with exponential backoff (1s → 2s → 4s, up to 3 attempts).
