Cathedral — Persistent Memory for AI Agents

Why this score

2 public GitHub projects have this in their committed setup (counted 2026-10-07). That counts people who kept it, not people who starred it. Private projects aren't visible, so the real number is higher.

Popularity score: 45/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank

Security

Scanned Nov 4, 2026 at the PyPI package cathedral-mcp@1.1.0, with Cisco's open-source skill-scanner.

What its code does:

• Reads environment variables and sends network requests with them API clients do this to send your key to the service. Check which service it talks to.cathedral_mcp/server.py and 3 more
• Makes network requestscathedral_mcp/server.py:153 and 1 more

Web addresses in its code:

• cathedral-ai.comcathedral_mcp/server.py:20

These are the sites named in the code, so it's where your data could go. It isn't a complete list: code can build addresses while it runs, and a few of these may be links rather than calls. Whatever you send also goes to the AI model you use.

A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
