Let ChatGPT read, and carefully edit, only the local folders you choose - through OpenAI's Secure MCP Tunnel, with no shell and no public port.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"keyhole-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

# Keyhole — local files for ChatGPT Let ChatGPT read, and carefully edit, only the local folders you choose. No shell, no public port. Keyhole connects your Mac, Linux or Windows computer to your private ChatGPT app through OpenAI's official Secure MCP Tunnel. Folders start read-only. Explicit local write grants allow hash-checked text edits with a private recovery history. ChatGPT cannot open other folders, run commands or widen its own access. ## Install ```sh uv tool install keyhole-mcp keyhole setup ``` On Windows, use PowerShell and request x64 Python, on both x64 and ARM PCs, then follow the [Windows guide](https://github.com/L-Jovi/keyhole/blob/v0.5.0/docs/windows.md): ```powershell uv tool install --python cpython-3.12-windows-x86_64-none --no-build keyhole-mcp ``` The package is **keyhole-mcp**; its command is **keyhole**. Do not install the unrelated package named `keyhole`. `uv` supplies Python and isolates dependencies; setup can download and verify the official tunnel client after confirmation. You need ChatGPT Developer mode and OpenAI Platform tunnel permissions. Installing this package alone does not create those permissions or a private ChatGPT app. Follow the [complete first-use guide](https://github.com/L-Jovi/keyhole/blob/v0.5.0/docs/setup.md), including the read-only example, account setup and PATH checks. Release wheels remain available on [GitHub Releases](https://github.com/L-Jovi/keyhole/releases). Verified scope: Apple-silicon macOS, Ubuntu x86_64 and Windows 11 with x64 Python; Python 3.11–3.14 in CI. Real ChatGPT acceptance was completed on macOS 15.7.7, Ubuntu 24.04 and a hosted Windows 11 ARM machine. Ubuntu 22.04 and Windows Server 2025 have automated coverage; no physical Windows consumer PC has been tested.
