vvk-charts-mcp: Instructions file for Codex

AGENTS.md

vvk-charts-mcp AGENTS.md is an instructions file for Codex, OpenCode from valderan/vvk-charts-mcp. It costs 1,384 tokens per session, scanned A, original, MIT.

A project guide for coding agents working on the vvk-charts-mcp Python project. It documents the setup, run, build, lint, type-checking, and test commands.

In plain words
What is it for?
It helps agents set up the Python environment, start the MCP server or command-line client, build the package, run code checks, and run tests.
Why use it?
It gives an agent the repository's working instructions in one place, reducing guesswork about how to install, run, and check the project.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is valderan/vvk-charts-mcp's own configuration. It tells Codex and OpenCode how to work on vvk-charts-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 vvk-charts-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

vvk-charts-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 8d 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.

    • vvk-charts-cli -> vvk_charts_mcp.client:main
  • Primary libraries: mcp, plotly, plotext, pydantic

Setup Commands

  • Install deps (including dev deps):
    • uv sync
  • Recreate env from lockfile:
    • uv sync --frozen

Run Commands

  • Run MCP server locally:
    • uv run vvk-charts-mcp
  • Run interactive CLI client:
    • uv run vvk-charts-cli

Build / Lint / Typecheck / Test

  • Build package artifacts:
    • uv build
  • Lint entire repo (Ruff):
    • uv run ruff check .
  • Auto-fix lint issues where safe:
    • uv run ruff check . --fix
  • Static type checking:
    • uv run mypy src
  • Run all tests:
    • uv run pytest

Single-Test Commands (important)

There is currently no tests/ directory in this repository. Use these commands once tests exist.

  • Run one file:
    • uv run pytest tests/test_example.py
  • Run one test function:
    • uv run pytest tests/test_example.py::test_specific_case
  • Run one test class:
    • uv run pytest tests/test_example.py::TestSuite
  • Run tests by keyword expression:
    • uv run pytest -k "terminal and dashboard"
  • Run with quiet output for agents:
    • uv run pytest -q

Repository Structure

  • src/vvk_charts_mcp/server.py: MCP tool schema + tool dispatch.
  • src/vvk_charts_mcp/client.py: interactive local smoke-test client.
  • src/vvk_charts_mcp/charts/: chart classes (line, bar, pie, scatter, area).
  • src/vvk_charts_mcp/terminal/: terminal chart/dashboard rendering + themes.
  • src/vvk_charts_mcp/utils/export.py: PNG/SVG/base64 export helpers.
  • ai/: reusable prompts/profiles for chart-focused agents.

Code Style Rules

These rules are inferred from current source and tool config. Follow existing conventions.

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.
