About
Git-aware safe file ops for AI agents: delete anything except git-tracked source code.
Security Report
This is a well-designed Go-based MCP server for safe file deletion that respects git-tracked files. The architecture is sound with clear separation of concerns, appropriate permission scoping, and comprehensive test coverage. No authentication is required (appropriate for a local tool), and no dangerous patterns detected. Minor code quality observations exist around error handling and logging, but these are not security issues. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity).

agent-guard-mcp
MCP server (written in Go, single static binary) for git-aware safe file operations. Give your AI agents (Claude Code, GitHub Copilot CLI, Cursor, …) free rein to delete what they build — while making it impossible for them to delete your git-tracked source code.
Policy: anything is deletable until it's tracked by a git repository.
Tools
| Tool | Purpose |
|---|---|
safe_delete | Delete files/dirs; refuses git-tracked files or dirs containing them. Supports dry_run. |
check_protection | Report whether paths are protected and why. |
guard_status | Summarize a directory: tracked (protected) vs untracked (deletable) counts. |
Install
Build the single static binary (no runtime dependencies):
go build -o agent-guard-mcp .
Or install directly:
go install github.com/kavachh/agent-guard-mcp@latest
Claude Code
claude mcp add agent-guard -- /path/to/agent-guard-mcp
GitHub Copilot CLI
In ~/.copilot/mcp-config.json:
{
"mcpServers": {
"agent-guard": { "command": "/path/to/agent-guard-mcp", "args": [] }
}
}
Any MCP client (generic stdio config)
{ "command": "/path/to/agent-guard-mcp", "args": [] }
Recommended agent instructions
Add to your CLAUDE.md / AGENTS.md / .github/copilot-instructions.md:
Never use
rmin the shell. Always delete files with thesafe_deleteMCP tool, which protects git-tracked source code.
Since safe_delete can never destroy tracked source, it is safe to auto-approve this server's tools in your client's permission settings.
Example
safe_delete { "paths": ["build/", "scratch.txt"] }
→ deleted (untracked)
safe_delete { "paths": ["src/main/java/App.java"] }
→ BLOCKED: git-tracked source file — use `git rm` deliberately if intended
Requirements
giton PATH- Go ≥ 1.24 (build only — the binary itself has zero dependencies)
Testing
24-case edge suite (tracked/staged/ignored files, nested repos, symlinks, dry-run, …):
go build -o agent-guard-mcp . && npm test
