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 | $0.00312 | $0.00312 |
| Opus 5 | $0.00156 | $0.00156 |
| Sonnet 5 | $0.00062 | $0.00062 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
secure-cluster-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 6d 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.
What it actually says
CLAUDE.md - Project Instructions
CRITICAL: CLUSTER SAFETY
This MCP server interacts with a shared university HPC cluster. Mistakes can:
- Waste compute resources (expensive)
- Block other researchers' jobs
- Corrupt research data
- Get user banned from cluster
MANDATORY RULES
- DRY_RUN=true by default - Never execute real SSH/SCP without explicit user confirmation
- Never spam cluster - Rate limit all commands (max 30/5min)
- Validate ALL paths - Must be under REMOTE_BASE_PATH, reject others
- Log tail only - Default 200 lines, never full logs unless requested
- No destructive commands - Never rm, never overwrite without confirmation
- Fail fast - If validation fails, raise error immediately, don't proceed
Before ANY cluster interaction:
- Check DRY_RUN flag
- Validate paths
- Check rate limits
- Log what would happen
Cluster File Transfer
Use scp via the MCP tools, never raw commands.
Cluster details (from .env):
CLUSTER_HOST- cluster IPCLUSTER_USER- usernameREMOTE_BASE_PATH- remote working directory
ALWAYS confirm with user before:
- Any file transfer
- Any job submission
- Any command that modifies remote state
Development
Use uv for Python environment management.
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.

secure-cluster-mcp CLAUDE.md is an instructions file published in the GitHub repository FlorianSp2000/secure-cluster-mcp (1 stars, last pushed 3mo ago), licensed MIT. It adds 312 tokens to every session, about $0.0016 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 2026-08-31.
