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 | $0.01205 | $0.01205 |
| Opus 5.5 | $0.00482 | $0.00482 |
| Sonnet 5.5 | $0.00241 | $0.00241 |
| Haiku 4.5 | $0.00120 | $0.00120 |
Grade A, and why
toolhive-studio 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 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.
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.

Project Overview
ToolHive Studio is an Electron desktop application for managing MCP (Model Context Protocol) servers. Built with React, TypeScript, and Vite. The Electron app bundles the ToolHive CLI (thv) binary.
Build and Development Commands
pnpm install # Install dependencies
pnpm run start # Start dev server with hot reload
pnpm run lint # Run ESLint
pnpm run type-check # TypeScript checking (both app and node configs)
pnpm run format # Format with Prettier
pnpm run test:nonInteractive # Run unit tests once
pnpm run test # Run unit tests in watch mode
pnpm run test:coverage # Unit tests with coverage
pnpm run e2e # Package + run Playwright e2e tests
pnpm run knip # Detect unused code
pnpm run generate-client # Fetch OpenAPI spec + regenerate API client
Husky/lint-staged automatically run lint + format on staged .ts/.tsx files. Run pnpm run type-check manually before committing — it is not covered by the hook.
Environment Requirements
- Node.js >=24 <25 (use
nvm use—.nvmrcis present) - pnpm package manager
- Docker daemon must be running (required by ToolHive)
Common Gotchas
- Docker must be running before
pnpm run start— ToolHive manages containers, so the daemon is required even in dev - Node version mismatch: wrong Node version can break other native modules. Always
nvm usefirst - Stale generated types: if type errors reference API types, run
pnpm run generate-clientto refresh - Electron test runner: unit tests run through Electron (
vitest:electron), not plain Node — required for native module compatibility - All commands from root: always run
pnpmcommands from the repository root, not from subdirectories

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.

toolhive-studio CLAUDE.md is an instructions file published in the GitHub repository stacklok/toolhive-studio (173 stars, last pushed today), licensed Apache-2.0. It adds 1,205 tokens to every session, about $0.0048 per session on Opus 5.5. 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.
