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 | $0.02253 | $0.02253 |
| Opus 5.5 | $0.00901 | $0.00901 |
| Sonnet 5.5 | $0.00451 | $0.00451 |
| Haiku 4.5 | $0.00225 | $0.00225 |
Grade A, and why
ToolMux CLAUDE.md scanned grade A with 1 finding 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 2mo 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.
Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.
- **Transport abstraction**: `HttpMcpClient` instances and `subprocess.Popen` instances are both stored in `self.server_processes` and differentiated via `isinstance()` checks. How it starts
The opening of the file, as written. The whole thing — 181 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md - ToolMux
Project Overview
ToolMux is an MCP (Model Context Protocol) server aggregation tool that achieves ~98.65% token reduction by exposing 4 meta-tools instead of loading hundreds of individual tool schemas upfront. It supports both stdio and HTTP/SSE transports.

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.

ToolMux CLAUDE.md is an instructions file published in the GitHub repository subnetangel/ToolMux (8 stars, last pushed 4mo ago), licensed MIT. It adds 2,253 tokens to every session, about $0.0090 per session on Opus 5.5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
