In plain words
What is it for?

This is aikts/yandex-tracker-mcp's own configuration. It tells Codex and OpenCode how to work on yandex-tracker-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything yandex-tracker-mcp configures →

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.

Security

Grade A, and why

yandex-tracker-mcp AGENTS.md 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 1mo 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.

Rules

Before naming a tool, writing a description, a CHANGELOG entry or a README section, read the rule that covers it - rules/README.md indexes them, and each names the test that enforces it. This file covers the rest: architecture, the Tracker API's behaviour, and how to test.

Project Overview

MCP Yandex Tracker is a Model Context Protocol (MCP) server that provides tools for interacting with Yandex Tracker API. It implements a FastMCP server with protocol-based architecture and optional Redis caching.

Commands

task              # Run all checks (format, lint, type checking, tests) - REQUIRED before commits
task format       # Auto-format code
task check        # Run type and format checking
task test         # Run tests
uv sync           # Install dependencies
uv run mcp-tracker # Run the server

Architecture

  • Protocols (mcp_tracker/tracker/proto/): Define API contracts (QueuesProtocol, IssueProtocol, GlobalDataProtocol, TemplatesProtocol, UsersProtocol, EntitiesProtocol, BoardsProtocol, ComponentsProtocol), each exposed on AppContext as queues / issues / fields / templates / users / entities / boards / components
  • Client (mcp_tracker/tracker/custom/client.py): Implements protocols, handles HTTP requests
  • Caching (mcp_tracker/tracker/caching/client.py): Wraps protocols with Redis caching
  • MCP Server (mcp_tracker/mcp/server.py): Server creation and configuration
  • MCP Tools (mcp_tracker/mcp/tools/): Tool definitions organized by category
    • _access.py: Access control helpers (check_issue_access, check_queue_access)
    • queue.py / queue_write.py: Queue read-only / write tools
    • field.py: Global field and metadata tools (read-only)
    • template.py: Issue and comment template tools (read-only)
    • board.py: Board and sprint tools (read-only)
    • component.py / component_write.py: Queue component read-only / write tools (queue_get_components itself lives with the queue tools)
    • issue_read.py / issue_write.py: Issue read-only / write tools
    • user.py: User tools (read-only)
    • __init__.py: Exports register_all_tools() which orchestrates tool registration
    • *_write.py modules are only registered when settings.tracker_read_only=False
    • project/portfolio/goal modules are only registered when settings.tracker_entities_enabled=True
  • Settings (mcp_tracker/settings.py): Pydantic settings from environment variables
  • All protocol methods accept optional auth: YandexAuth | None parameter for OAuth support.
  • All Pydantic models for Yandex Tracker entities inherit from BaseTrackerEntity.

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.
