What is yandex-keyword-research?

A keyword-research tool for Russia and other Commonwealth of Independent States markets, using data from Yandex, a major Russian search engine.

Use it to find related queries, see whether interest is rising or falling, compare regions, inspect current search results, and check a connected site’s Yandex rankings.

It helps replace guesswork about what people search for with search-volume, trend, and regional data.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00060	$0.00426
Opus 5	$0.00030	$0.00213
Sonnet 5	$0.00012	$0.00085
Haiku 4.5	$0.00006	$0.00043

Measured 12d ago against content hash 50a6bd002284, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-12, from the pricing page.

Security

Grade A, and why

yandex-keyword-research scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Yandex Keyword Research

Research keywords and search trends for Russian and CIS markets using Yandex tools.

Available Tools

mcp__yandex-wordstat__top-requests - Find popular queries containing a keyword (costs 1 quota unit)
mcp__yandex-wordstat__dynamics - Analyze search volume trends over time (costs 2 quota units)
mcp__yandex-wordstat__regions - See regional distribution of search interest (costs 2 quota units)
mcp__yandex-wordstat__get-regions-tree - Get region hierarchy for filtering (free)
mcp__yandex-search__search - See what currently ranks in Yandex for the keyword
mcp__yandex-webmaster__get-popular-queries - Check if user's site ranks for terms (requires Webmaster access)

Workflow

Get popular queries: Start with top-requests to find related searches and volumes
Analyze trends: Use dynamics to see if interest is growing or declining
Regional breakdown: Use regions to find which areas have highest interest
SERP analysis (optional): Use search to see current ranking content
Own site check (if Webmaster configured): Check user's site performance for these terms

Output Guidelines

Adapt output language to match the user's language
Present search volumes with context (high/medium/low for the market)
Highlight trend direction (growing, stable, declining) with percentage change
Show top 5-10 regions by volume and by affinity index
Include actionable insights based on the data

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
