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 | $0.05230 | $0.05230 |
| Opus 5 | $0.02615 | $0.02615 |
| Sonnet 5 | $0.01046 | $0.01046 |
| Haiku 4.5 | $0.00523 | $0.00523 |
Grade C, and why
holoviz-mcp AGENTS.md scanned grade C with 2 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 9d 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.

AGENTS.md - HoloViz MCP Server
A README for AI coding agents to effectively contribute to the HoloViz MCP project.
Repository Overview
Project: HoloViz MCP - Model Context Protocol server for the HoloViz ecosystem Purpose: Provides AI assistants with intelligent access to Panel, hvPlot, and HoloViz documentation Language: Python 3.11+ Build System: Pixi (conda-based) + Hatchling (PEP 517) Framework: FastMCP (Python MCP SDK) Key Dependencies: ChromaDB, sentence-transformers, Panel
Project Statistics
- Source Files: ~20 Python modules in
src/holoviz_mcp/ - Test Coverage: Unit tests, integration tests, and UI tests (Playwright)
- Total Dependencies: ~240 packages (includes ML/AI dependencies)
- Platforms: macOS (ARM64/x64), Linux (x64/ARM64), Windows (x64)
Quick Start - ALWAYS RUN FIRST
Environment Setup
CRITICAL: This project uses Pixi for reproducible environments. DO NOT use pip/conda directly.
# 1. Install Pixi (if not already installed)
curl -fsSL https://pixi.sh/install.sh | bash
# 2. Clone and enter the repository
cd holoviz-mcp
# 3. Install development environment
pixi install
# 4. Install pre-commit hooks (MANDATORY BEFORE ANY COMMITS)
pixi run pre-commit-install
# 5. Install the package in editable mode
pixi run postinstall
Expected output: Environment should install ~240 packages. First run takes 5-10 minutes.
Verification
# Verify installation
pixi run holoviz-mcp --help
# Run tests to ensure everything works
pixi run test
# ✓ All tests should pass on a clean checkout
Pre-Commit Hooks - MANDATORY BEFORE PRs
ALWAYS RUN before committing or creating pull requests:
pixi run pre-commit-run
# ✓ Takes 1-3 minutes on first run (installs hook environments)
# ✓ Subsequent runs are fast (<30 seconds)
# ✓ Auto-fixes many issues (formatting, imports, trailing whitespace)
What Gets Checked
- Ruff: Import sorting (isort), formatting, linting
- MyPy: Type checking
- Prettier: CSS/JSON/YAML formatting
- Codespell: Spell checking
- Pre-commit hooks: Trailing whitespace, end-of-file, TOML/JSON validation
- Clean notebook: Jupyter notebook cleaning
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.

holoviz-mcp AGENTS.md is an instructions file published in the GitHub repository MarcSkovMadsen/holoviz-mcp (34 stars, last pushed 8d ago), licensed BSD-3-Clause. It adds 5,230 tokens to every session, about $0.0261 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
