SiteGuardian MCP — Examples & Client Configurations

Client configurations, copy-paste examples, and the MCP server manifest for the SiteGuardian Model Context Protocol server.

Note: This repository contains examples and client integration code only. The MCP server itself is hosted at https://mcp.siteguardian.io and is operated as a SaaS — server source is closed. Everything in this repo is MIT-licensed and free to fork.

What is the SiteGuardian MCP server?

A hosted MCP endpoint that lets Claude Desktop, Claude Code, Cursor, Windsurf, and VS Code Copilot query website-monitoring data and run security/compliance scans through natural-language tool calls.

• Endpoint: https://mcp.siteguardian.io (or the canonical https://siteguardian.io/mcp)
• Transport: Streamable HTTP
• Hosting: Hetzner, Germany — EU data residency
• Documentation: https://siteguardian.io/docs/mcp

Five tools

Tool	Auth	Purpose
scan_domain	anonymous	One-off security scan, A–F grade + top 3 issues + permalink
list_monitored_domains	Bearer	Domains under continuous monitoring for the account
get_domain_status	Bearer	Current grade + active issues for a monitored domain
get_drift_events	Bearer	Recent posture changes (TLS, DNSSEC, headers, cookies, JS hosts)
get_fix_recommendations	Bearer + paid plan	nginx/Apache/DNS snippets + verify commands

Try the anonymous tool (no setup required)

curl -X POST https://mcp.siteguardian.io/ \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"scan_domain","arguments":{"domain":"example.com"}}}'

Rate-limited to 10 calls/hour/IP. Cached for 2h per domain. Full curl/Python/JS examples in examples/.

Install in your client

All clients use the same endpoint. Copy-paste configs in clients/:

• Claude Desktop — clients/claude-desktop.json
• Claude Code (CLI) — clients/claude-code.sh
• Cursor — clients/cursor.json
• Windsurf — clients/windsurf.json
• VS Code / Copilot — clients/vscode.sh

Authentication

The scan_domain tool is anonymous. The four monitoring tools require a Bearer key:

1. Sign in at https://siteguardian.io
2. Open Settings → API & Integrations
3. Click Generate key, name it, copy it
4. Add to your client config:

   "headers": {"Authorization": "Bearer sg_live_..."}
   

API keys are available on the Monitor, Compliance, and Enterprise plans.

Privacy

• EU-hosted. Hetzner Germany. No US sub-processor.
• No LLM in the response path. Tool answers are deterministic from monitoring data.
• No training on your queries. Logged for abuse prevention and billing only.
• Audit trail. Every tool call is recorded in the SHA-256 hash chain.

Server manifest

The full machine-readable MCP server manifest is in server.json — this is the file consumed by the Anthropic MCP Registry and the various community directories.

Roadmap

• OAuth 2.1 (per current MCP spec)
• resources and prompts in addition to tools
• Listing in the official Anthropic MCP Registry
• Listing on Smithery and mcp.so
