Nothing serious here today

Today is the operative word: we check SNAC Archives every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

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 snac-archives-mcp -- uvx snac-archives-mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "snac-archives-mcp": {
      "args": [
        "snac-archives-mcp"
      ],
      "command": "uvx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.snac-archives-mcp]
command = "uvx"
args = ["snac-archives-mcp"]
.cursor/mcp.json
{
  "mcpServers": {
    "snac-archives-mcp": {
      "args": [
        "snac-archives-mcp"
      ],
      "command": "uvx"
    }
  }

        "snac-archives-mcp"
      ],
      "command": "uvx"
    }
  }
}

This one needs environment variables set before it will start: SNAC_API_URL (The SNAC REST API endpoint.), SNAC_CACHE_DIR (Directory for the on-disk response cache.), SNAC_TIMEOUT (HTTP timeout in seconds. Holdings lists get 120 s of their own.), SNAC_CONTACT (An email address or URL appended to the User-Agent, so SNAC can reach whoever runs the server.). The author declared them in the registry entry; get the values from the project itself.

SNAC Archives — questions

Answers built from our own checks of this server.

Why is there no uptime for SNAC Archives?
SNAC Archives 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 snac-archives-mcp was installed 441 times last week.
How do I connect SNAC Archives?
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 snac-archives-mcp straight from pypi; nothing to host, nothing to sign up for.
How many people use SNAC Archives?
The pypi package snac-archives-mcp was installed 441 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is SNAC Archives open source?
Yes — it is published under the MIT licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
