Check a link source before submitting a site to it, verify a listing after it goes live, and audit a site's own backlink profile for patterns that read as link spam. Use when the user wants to submit a site, tool or repository to directories, awesome lists or guest-post sites, asks whether a directory or link source is safe or worth it, wants to check whether a backlink is followed, asks for a backlink audit or spam check after a Google spam update, asks which sites link to their competitors…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Backlink guard Four jobs, in the order a careful person does them: find the pages your searchers already land on, check a place before you submit, check the link after it is live, and look at your own profile now and then. The tool gives signals with their evidence. It does not submit anything, and it is not Google's verdict. Anything you send on the user's behalf waits for their yes (section 3). ## Before you run anything 1. Run the pinned release from PyPI: `uvx backlink-guard==0.11.2 <command>` when `uv` is there, else `pip install backlink-guard==0.11.2` and the `backlink-guard` command. Never run a clone of the repository's default branch. The commands below are written as `backlink-guard`; run them as `uvx backlink-guard==0.11.2 …`. Python 3.10 or newer, no dependencies. The log, the paid answers and the networks seen before are kept in `~/.backlink-guard` (`BACKLINK_GUARD_STATE` moves them). 2. Keys are optional, and each adds signals: - `GLASSER_API_KEY` (https://link.glasser.ai/JasonZhu), the first choice: spam scores, Google search history, new and lost referring domains by week, anchors, competitors' referring domains, AI Overviews (`cited`). …

How to install
mdr add zhuyansen/backlink-guard/backlink-guard@sha256:148a747440916f08The line at the top of this page pins the label git:20261031.d00cd64, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
