ClaudeBrain

ClaudeBrain is an open-source AI developer tool for penetration testing and bug bounty agent workflows with Claude and Obsidian context. The official source for this listing is the public GitHub repository at https://github.com/Encod3d-Sec/ClaudeBrain. During this creation run, GitHub metadata showed 197 stars, 32 forks, 0 open issues, Python as the main language, and a latest public push dated 2026-07-17. The upstream description says: Karpathy LLM based claude harness for PenetrationTesting / Bugbounty using obsidian. That source-backed description is the reason OpenTools treats this as a builder-relevant tool rather than a generic news item. The project gives developers a concrete repository to inspect, test, fork, and compare with their current AI workflow before relying on it in sensitive environments. The safest evaluation path is practical. Start by reading the README, checking the install steps, reviewing dependency permissions, and running the smallest available example in a disposable workspace. Watch for which files the tool reads, which services it calls, whether model API keys are required, and how it behaves with private data. Those checks matter because AI developer tools often sit close to production code, logs, credentials, or customer-facing systems. ClaudeBrain is most useful for teams that want a source-visible way to experiment with claude harness for security testing. A solo builder can use it to test a workflow quickly. A platform team can review whether the repository fits internal security rules. An AI engineering team can compare the project with its current stack and decide whether it reduces repeated prompting, improves context, or makes experiments easier to reproduce. Pricing is recorded as free/open-source access because the selected source is a public GitHub repository. Real operating cost can still include model API usage, local compute, cloud runners, storage, paid data sources, or hosted versions that are separate from the repository. Review MIT License terms and upstream documentation before using it commercially. If the project later publishes formal plans, this page should be updated from official pricing material. Verification note: OpenTools used the repository URL, GitHub API metadata, README text, and the triage source signal as source material. This page does not invent private benchmarks, roadmap claims, customer counts, or hidden paid features. Treat it as a source-backed listing that points builders to the current upstream project. README excerpt reviewed from the source repository: ClaudeBrain An AI powered penetration testing and bug bounty knowledge base and automation harness for Claude Code. It turns an Obsidian vault into an opinionated offensive security workflow: a searchable wiki of 500+ hacking technique pages, per vulnerability "hunt" skills, deterministic hooks that fire the right skill at the right moment, and a state first engagement model that stops you (and the model) from repeating work.
