Semantic Memory Operating System — persistent memory MCP server for Claude Code
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":"smos-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

On a 20-file codebase, by the time Claude reaches synthesis it's carrying 40,000+ tokens of raw source — most of which it already processed, will never need again verbatim, and is paying for on every single API call. **Caveman** compresses what Claude *says*. **SMOS** compresses what Claude *holds* — the files, the prior analysis, the context window itself. --- ## How it works SMOS is an MCP server that gives Claude a persistent memory layer: FAISS vector search + SQLite, powered by a local LLM (qwen2…
