README

`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.

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)
