What the code does

We read the source, 18 h ago · rules 3dff92dd89df

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

    return os.path.isdir(os.path.join(cache_dir, repo_dir))

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add tether -- uvx tether-memory

This one needs environment variables set before it will start: TETHER_DB (Path to the SQLite memory file. Defaults to the platform data dir (e.g. ~/.local/share/tether/memory.db).), TETHER_SEMANTIC (Set to 0 to force keyword-only recall. Semantic recall needs the [semantic] extra and is on by default when available.), TETHER_SYNC_URL (Optional libSQL/Turso primary URL to sync memory across devices. Leave unset for local-only.), TETHER_SYNC_TOKEN (Auth token for TETHER_SYNC_URL.). The author declared them in the registry entry; get the values from the project itself.

Tether — questions

Answers built from our own checks of this server.

Why is there no uptime for Tether?
Tether runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package tether-memory.
How do I connect Tether?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls tether-memory straight from pypi; nothing to host, nothing to sign up for.
Is Tether open source?
Yes — it is published under the MIT licence, written in Python, 1 stars on GitHub and 4 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
