`xmlriver-mcp`

MCP server for XMLRiver — Google/Yandex SERP parsing and Yandex Wordstat keyword frequency data via XML API.

mcp-name: io.github.artgas1/xmlriver-mcp

What it does

Gives Claude / Cursor / Windsurf direct access to:

Google SERP parsing (organic, ads, FAQ, knowledge graph, AI Overview) for any country / region / device
Yandex SERP parsing (Russian-speaking markets — primary use case)
Yandex Wordstat keyword frequency, history, similar queries (Yandex's keyword volume tool)
Indexing check — is this URL in Google/Yandex index?
Account ops — balance, tariff, cost per 1k requests

First MCP for XMLRiver — fills a gap for Russian SEO research and Yandex-aware analysis. Pay-as-you-go (~25 ₽ / 1000 requests on Basic tariff).

Demo

Claude queries wordstat_query and parses real frequency data from Yandex. Same flow works for google_search, yandex_search, indexing checks, and account ops.

Quickstart

bash

uvx xmlriver-mcp

Tools

Tool	What it does
`google_search`	Parse Google SERP for a query — country, language, device, page, date filter, extra blocks (ads, FAQ, knowledge graph, AI Overview)
`yandex_search`	Parse Yandex SERP — region, language, device, page, date filter, extra blocks
`yandex_search_api_v2`	Yandex Search API v2 (official) via XMLRiver — cleaner structured output
`wordstat_query`	Yandex Wordstat keyword frequency, device breakdown, history, similar queries
`check_url_indexed`	Check if URL is indexed in Google or Yandex
`get_balance`	Current XMLRiver balance in rubles
`get_tariff`	Current XMLRiver tariff name (Basic / Pro / Mega / Giga)
`get_tariff_expire`	Tariff expiration date (for prepay tariffs)
`get_cost`	Cost per 1000 requests for a given engine (google / yandex / yaxml / wordstat)

All tools are read-only (annotated with readOnlyHint: true). No destructive operations.

Common use cases

SEO position tracking — yandex_search(query="...", region=213) for own/competitor ranking
Keyword research — wordstat_query(query="купить iphone", history_period="monthly") for demand validation + seasonality
Featured snippet hunting — google_search(additional_blocks="faqsnippet,knowledge_graph,zeroposition") to see what owns the answer box
Indexation monitoring — check_url_indexed(url="https://your-site.com/new-page") after publishing
Cross-region comparison — same query, different region/country for Yandex/Google to see geographic variance

Local development

bash

git clone https://github.com/artgas1/xmlriver-mcp
cd xmlriver-mcp
uv sync --all-extras

# Run unit tests (no API key needed)
uv run pytest tests/unit -v

# Run integration tests (requires XMLRIVER_USER / XMLRIVER_KEY)
XMLRIVER_USER=... XMLRIVER_KEY=... uv run pytest tests/integration -v -m integration

# MCP Inspector — interactive
XMLRIVER_USER=... XMLRIVER_KEY=... npx @modelcontextprotocol/inspector uv run python -m xmlriver_mcp.server

# MCP Inspector — CLI smoke test (list tools)
npx @modelcontextprotocol/inspector --cli "uv run python -m xmlriver_mcp.server" --method tools/list

Architecture

Stack: Python 3.10+ / FastMCP / httpx / tenacity / pydantic
Transport: stdio (default)
No external SDK dependency — direct REST via httpx + custom XML parser
Retry strategy: 3 attempts with exponential backoff on network errors (not on HTTP 4xx)
Logging: stderr only (stdio protocol requires stdout for JSON-RPC)
