Built arc-gate-mcp with Claude’s help as a wrapper that sits between Claude Code and any MCP server it connects to. Every tool result gets inspected before Claude sees it, so if a file or webpage contains hidden instructions trying to redirect Claude’s behavior, they get blocked first. Built it specifically because Claude Code reading untrusted files and URLs is the exact attack surface for indirect prompt injection. The fix is one config change in claude_desktop_config.json. Free to try, get a key at https://bendexgeometry.com/ then wrap any existing MCP server with arc-gate-mcp. GitHub: https://github.com/9hannahnine-jpg/arc-gate-mcp submitted by /u/Turbulent-Tap6723
