Sovr MCP Proxy adds safety layer to prevent LLM destructive commands

What it is

Sovr MCP Proxy is a safety layer that intercepts commands before execution to prevent LLMs from running destructive operations on your system. The developer created it after a local model nearly executed rm -rf on their home folder while "organizing files."

Blocked patterns

• rm -rf / rmdir / destructive file operations
• DROP TABLE / DELETE FROM (SQL commands)
• curl | sh / wget | bash (piped execution patterns)
• chmod 777 / risky sudo usage

Compatibility

The proxy works with Claude Code and any MCP-compatible client. The developer mentions planning Ollama integration next.

Setup

Configuration uses this MCP setup:

{
  "sovr-gate": {
    "command": "npx",
    "args": ["sovr-mcp-proxy"]
  }
}

Technical details

The tool is available as an npm package at https://www.npmjs.com/package/sovr-mcp-proxy under the BSL-1.1 license. It functions as an MCP proxy that sits between the LLM and command execution.
