Yandex Metrika MCP

Read-only MCP server for Yandex Metrika (Yandex Metrica, Яндекс Метрика). Connect it to Claude, Cursor, VS Code, Codex or any MCP client and ask about traffic, sources, landing pages and goals. Every answer comes with exact dates, the counter time zone, sampling status, filters and provenance, so the numbers can be checked.

Документация на русском: README.ru.md и docs/ru.

Status: 1.0.0, the first stable release; tool names, arguments and outputs follow semantic versioning. Covered by tests against synthetic data and a simulated API, and checked with a live Yandex sign-in and reports on macOS. Other clients and platforms are tracked in docs/release-checklist.md.

Why this server

• Sign in through the browser. No token pasting, no OAuth app of your own; the token never enters the chat.
• Numbers you can verify. Calendar periods in the counter time zone, complete days by default, strict accuracy that refuses sampled data instead of calling it exact, API totals instead of sums of visible rows.
• Several accounts and clients. Isolated connections with their own counters; nothing is shared between them.
• Full exports. Background CSV/JSON export of every row with checksums, a manifest and resume after a restart.
• Small, predictable surface. 13 tools, 3 prompts. Read-only: no write endpoints, no raw HTTP tool.

Install

Requires Node.js 22.13 or later. No API key and no OAuth app of your own: after installing, ask the assistant to connect Yandex Metrika and sign in through the browser.

One command (writes the client config and keeps a backup):

npx -y @dev-crabs/yandex-metrika-mcp setup --client claude-desktop   # or claude-code, cursor, vscode, windsurf, codex

One click:

[Install in Cursor] Install in VS Code

Claude Code:

claude mcp add --scope user yandex-metrika -- npx -y @dev-crabs/yandex-metrika-mcp

Any MCP client (mcpServers format; VS Code uses servers with "type": "stdio"):

{  "mcpServers": {    "yandex-metrika": { "command": "npx", "args": ["-y", "@dev-crabs/yandex-metrika-mcp"] }  }}

On Windows some clients cannot start npx directly; use "command": "cmd", "args": ["/c", "npx", "-y", "@dev-crabs/yandex-metrika-mcp"], which is what setup writes there. Claude Desktop users can also install the .mcpb bundle from the GitHub release. AI agents installing the server should follow llms-install.md.

Restart the client and ask: "Connect Yandex Metrika and compare the last two weeks by traffic source." The assistant calls metrika_connect and gives you a local sign-in link. Try it without an account: the synthetic conn_demo connection is always available.

Example questions

• "Compare the last two complete weeks by visits and target visits of goal 3001."
• "Which landing pages brought the most leads for goal X last month?"
• "Show weekly visits since the start of the quarter."
• "Export all traffic sources for October to CSV for Excel."

Tools

Prompts: weekly_review, traffic_drop, landing_conversion.

Data and privacy

Report data you request is sent to your AI client and its model provider; tokens never are. Tokens live in the OS credential store (macOS Keychain, Windows Credential Manager, Linux Secret Service). Without one, the server refuses to store tokens unless you explicitly choose an unencrypted user-only file. URL query strings are removed from labels by default. No telemetry. Details: docs/ru/privacy-security.md.
