Agentguard

agentguard-mcp

MCP server for @mukundakatta/agentguard. Lets Claude Desktop, Cursor, Cline, Windsurf, Zed, or any other MCP client check whether a URL is allowed under a network-egress policy before any fetch.

npx -y @mukundakatta/agentguard-mcp

Three tools:

• check_url — single URL check: returns { allowed, reason } without making any actual request.
• check_urls_batch — batch check with per-URL decisions plus a summary.
• validate_policy — sanity-check a policy spec for empty allowlists, overly broad * wildcards, and malformed host patterns.

Add to your client

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "agentguard": {
      "command": "npx",
      "args": ["-y", "@mukundakatta/agentguard-mcp"]
    }
  }
}

Same shape for Cursor (~/.cursor/mcp.json), Cline, Windsurf, Zed.
