Nothing serious here today

Today is the operative word: we check A2CR every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Claude Code Claude Desktop Codex Cursor VS Code

run in your terminal

claude mcp add a2cr-mcp -- uvx a2cr-mcp

~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "a2cr-mcp": {
      "args": [
        "a2cr-mcp"
      ],
      "command": "uvx"
    }
  }
}

~/.codex/config.toml

[mcp_servers.a2cr-mcp]
command = "uvx"
args = ["a2cr-mcp"]

.cursor/mcp.json

{
  "mcpServers": {
    "a2cr-mcp": {
      "args": [
        "a2cr-mcp"
      ],
      "command": "uvx"
    }
  }
}

.vscode/mcp.json

        "a2cr-mcp"

    }
  }
}

This one needs environment variables set before it will start: A2CR_LOCAL_DB (Optional path for the local A2CR SQLite database. Leave unset to use the OS default app-data location.). The author declared them in the registry entry; get the values from the project itself.

A2CR — questions

Answers built from our own checks of this server.

Why is there no uptime for A2CR?

A2CR 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 a2cr-mcp was installed 157 times last week.

How do I connect A2CR?

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 a2cr-mcp straight from pypi; nothing to host, nothing to sign up for.

How many people use A2CR?

The pypi package a2cr-mcp was installed 157 times in the last week. Week over week that is -27%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is A2CR open source?

Yes — it is published under the Apache-2.0 licence, written in Python, 2 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
