Yes. Run a verifier on your own machine instead of a cloud service. RedMirror Reflection is an MCP server your coding agent drives locally: the compiled kernel checks the code on your box and uses no tokens, so your source never leaves for the check and there is nothing for a vendor to retain. The only thing that can egress is your agent's own model call.
In an AI-assisted review, two things could send your code off the box: the analysis engine phoning home with your source, and the coding model's own API call. RedMirror Reflection removes the first entirely. The verify kernel is a compiled binary that runs the analysis locally and needs no network and no tokens to decide whether a bug is real, so there is no repository upload and no per-scan data sent to a vendor. The second, the model, is a property of the coding agent you point it at, not of Reflection: a hosted model (Claude, GPT, Gemini via API) can include code in its prompt context. If you want that closed as well, run your agent on a self-hosted model and the whole loop stays on your infrastructure.
Your coding agent proposes a suspected bug as a small state-machine model. The compiled kernel then searches every reachable state locally and returns a concrete, replayable attack path, or a bounded proof that none exists. That search runs on your CPU, calls nothing, and uses no tokens. Because no cloud service sits in the loop, there is no source upload, no per-scan payload to a vendor, and no server-side copy for anyone to retain or leak. Activating your license validates your key with the license server, and that request carries your key only, never your source.
| Approach | Where the analysis runs | What leaves your machine | Retention of your code |
|---|---|---|---|
| Cloud / SaaS scanner | Vendor servers | Your source, uploaded or via repository access | Held per the vendor's policy |
| Hosted-LLM code review (API) | The model provider | Code sent as prompt context | Held per the provider's policy |
| RedMirror Reflection (local verify) | Your machine | Nothing for the check — only your agent's model call, which you choose | None server-side; nothing is uploaded |
The distinction that matters for compliance is where the source goes. A cloud scanner and a hosted-LLM review both put your code on someone else's server to analyze it. Reflection does the analyzing on your box, so the verify step has nothing to send and nothing for a third party to keep.
Yes. Local analysis with no source transmitted is exactly the fit for proprietary, regulated, or otherwise private repositories. Reflection is a licensed binary rather than open source, but the licensing governs running the tool, not access to your code: your source and your model never pass through us. For a fully air-gapped loop, where even the coding model is self-hosted, see the air-gapped review page.
Use it when source must stay in-house and you want a check that egresses nothing for the verification and works offline: proprietary code, regulated environments, private repos. Keep the model caveat in view: if your coding agent runs on a hosted model, code context still reaches that provider — that is the model, not Reflection; for a fully closed loop, pair it with a self-hosted model (the air-gapped combo). And Reflection is a reachable logic and state verifier, not a secrets scanner or a dependency-CVE scanner; pair it with tools built for those.
Install the binary, activate your licence, and wire it into your coding agent. From then on you ask the agent to "verify this change" and the kernel does the checking locally, reporting only what it can prove.
curl -fsSL https://dist.redmirror.io/install.sh | sh # macOS / Linux redmirror-reflect license activate <your-key> redmirror-reflect init claude # or cursor, codex, gemini, pi, dsh, ci
On Windows, install with irm https://dist.redmirror.io/install.ps1 | iex. Any MCP-capable agent works; running init for an unknown agent prints the exact MCP wiring to add by hand. Full per-editor setup is in the docs.
Yes. Run a verifier that works on your own machine instead of a cloud service. RedMirror Reflection is an MCP server your coding agent drives locally, and its compiled kernel checks the code on your box using no tokens. Your source never leaves for the check, so there is no repository upload and nothing for a vendor to store.
No. The verify kernel is a local binary that runs the analysis on your machine and needs no network and no tokens to decide whether a bug is real. The only thing that can leave your machine is your coding agent's own model call, which is a property of the agent you choose, not of Reflection.
There is no server-side copy to retain, because nothing is uploaded for the check. Verification runs entirely on your machine, so the analysis step has zero data retention. Activating your license contacts the license server with your key only, never your source.
Yes. Because the analysis is local and no source is transmitted, private and proprietary code is a natural fit. The engine handles JavaScript/TypeScript, Python, Go, Rust, Java, C#, Ruby, PHP, and C/C++.
The verify step works fully offline: the kernel runs locally and uses no tokens. Whether the whole review is offline also depends on your coding agent's model. If your agent uses a hosted model, prompt context can reach that provider, so run your agent on a self-hosted local model to close the loop.
A cloud scanner uploads your source or connects to your repository and runs the analysis on a vendor server, governed by that vendor's retention policy. RedMirror Reflection runs the analysis on your machine and proves each finding with a replayable attack path, so nothing egresses for the check and there is no vendor-held copy of your code.
