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 | $0.03977 | $0.03977 |
| Opus 5 | $0.01988 | $0.01988 |
| Sonnet 5 | $0.00795 | $0.00795 |
| Haiku 4.5 | $0.00398 | $0.00398 |
Grade A, and why
homelab-mcp CLAUDE.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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 466 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Development Guide for Homelab MCP
Project Overview
Repository: https://github.com/bjeans/homelab-mcp Docker Hub: https://hub.docker.com/r/bjeans/homelab-mcp Version: 3.0.0 (Released: 2026-01-14) License: MIT Purpose: Open-source MCP servers for homelab infrastructure management through Claude Desktop
⚠️ Breaking Changes in v3.0: See MIGRATION_V3.md for upgrade guide.
This project provides real-time monitoring and control of homelab infrastructure through 7 specialized MCP servers, including Docker/Podman containers, Ollama AI models, Pi-hole DNS, Unifi networks, UPS monitoring, and Ansible inventory management via the Model Context Protocol.
Deployment Options:
- Native Python installation (recommended for development)
- Docker container from Docker Hub:
bjeans/homelab-mcp:latest(recommended for production) - Docker build from source (for customization)
Core Philosophy
- Security First - Never commit credentials, IPs, or sensitive data
- Configuration as Code - All settings via environment variables or Ansible inventory
- User Privacy - All example files use placeholder data
- Production-Grade - Code quality suitable for critical infrastructure
- Open Source - Community-friendly, well-documented, MIT licensed

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.

homelab-mcp CLAUDE.md is an instructions file published in the GitHub repository bjeans/homelab-mcp (41 stars, last pushed 2mo ago), licensed MIT. It adds 3,977 tokens to every session, about $0.0199 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
