What is yandex-direct-mcp-plugin CLAUDE.md?

A set of instructions for a Claude Code plugin that manages Yandex.Direct advertising campaigns, which are online ad campaigns on Yandex. It uses a Python command-line tool and the Yandex.Direct API through an MCP server.

Use it when developing or maintaining this plugin, especially for working with campaign operations, service tools, authentication profiles, and the documented implementation rules.

It keeps campaign operations behind one command-line boundary and documents the project's architecture, commands, authentication, and available tools.

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	$0.02587	$0.02587
Opus 5	$0.01293	$0.01293
Sonnet 5	$0.00517	$0.00517
Haiku 4.5	$0.00259	$0.00259

Security

Grade B, and why

yandex-direct-mcp-plugin CLAUDE.md scanned grade B with 3 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 2d 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.

CLAUDE.md

Claude Code plugin for managing Yandex.Direct advertising campaigns. Wraps the direct Python CLI via an MCP server (FastMCP, stdio); auth delegated to direct auth profiles. Status: Implemented.

Architecture

MCP (server/main.py) → direct CLI → tapi-yandex-direct → Yandex.Direct API

MCP never calls Yandex.Direct directly — always through direct, even to work around a missing/broken CLI feature. No urllib, raw HTTP, or tapi-yandex-direct imports. File upstream issues in axisrow/direct-cli and wait for the release.
direct is the only execution/transport boundary. WSDL/Reports spec wins when CLI convenience names drift.
Machine-readable parity source: server/contract.py (PUBLIC_CONTRACT, TRANSPORT_BLOCKED_OPERATIONS, RENAMED_TOOL_MIGRATION).
server/cli/runner.py — DirectCliRunner subprocess wrapper. server/tools/*.py — 149 default tools across 42 modules, one module per service; the contract reserves 23 additional tools for opt-in bundles loaded by server/optional_tools.py as their implementation modules land. server/tools/helpers.py — shared validation (parse_ids, check_batch_limit).

Commands

Task	Command
Install	`pip install -e ".[dev]"` (add `,docs` for Sphinx)
All tests (cassettes, no token)	`pytest`
Single test	`pytest tests/test_campaigns.py::test_campaigns_list -v`
Mock edge-case tests	`pytest -m mocks`
Integration tests (needs `.env` + a `direct` auth profile)	`pytest -m integration`
Record cassettes	`pytest --record`
Sanitize / audit cassettes	`python -m tests.sanitize` · `python -m tests.audit`
Lint / format	`ruff check .` · `ruff format .`
Type check	`mypy .`
Run server locally	`python3 server/main.py`
Build docs	`cd docs && make html`

Environment

Python ≥ 3.11, no Node.js. Deps: mcp, direct-cli. Build config: pyproject.toml (PEP 621).
Auth (simplest first): set YANDEX_DIRECT_TOKEN in ~/.claude/settings.json env, or run auth_login/auth_setup (saved to ~/.direct-cli/auth.json). direct-cli resolves explicit env creds before the active profile.
Creds: YANDEX_DIRECT_TOKEN, YANDEX_DIRECT_LOGIN, YANDEX_DIRECT_CLI_PATH. Finance/master tokens are env-only: YANDEX_DIRECT_FINANCE_TOKEN, YANDEX_DIRECT_MASTER_TOKEN.
Optional registration (server/optional_tools.py, default = none): YANDEX_DIRECT_OPTIONAL_TOOLS accepts browser, trackingparams, a comma-separated combination, or all. The import gate runs before tool-surface filtering, so profiles/groups can subtract tools after their bundle is loaded; surface allow-lists do not load bundles by themselves.
Browser read deployment: YANDEX_DIRECT_BROWSER_PROFILE_DIR and YANDEX_DIRECT_BROWSER_CHROME_PROFILE select the Chrome profile; YANDEX_DIRECT_BROWSER_HEADFUL=1 shows the browser. These are server env settings, not MCP tool parameters.
Tool-surface selection (server/config.py, default = all 149 registered tools): YANDEX_DIRECT_TOOL_PROFILE (full|core|analytics|campaign-editor), YANDEX_DIRECT_ENABLED_GROUPS/_DISABLED_GROUPS (service / action / product-area / financial), YANDEX_DIRECT_ENABLED_TOOLS/_DISABLED_TOOLS.

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.
