nickpending mcp censys
mcp-censys is a MCP server that taps into the Censys Search API for real-time domain, IP, and FQDN reconnaissance
WHAT IT CONNECTS
nickpending mcp censys 为 AI Agent 提供什么
- **Conversational Queries**: Natural language access to Censys intel
- **Domain and IP Lookup**: Get DNS names, ASN, services, and TLS context
- **New FQDN Discovery**: Find recently seen subdomains from DNS and cert data
- **MCP-Compatible Tools**: Use directly from Claude Desktop
- **MCP Prompt Templates**: ✨ Built-in structured guidance templates that instruct Claude exactly how to analyze and present domain data ([learn more about MCP Prompts](https://modelcontextprotocol.io/docs/concepts/prompts))
- **Dockerized with .env support**: Secure, repeatable usage
- **Lightweight API Client**: Based on Censys Python SDK
- **lookup_domain** - Get comprehensive IPs, DNS names, services, and ASN info for a domain (aggregates data across all results) with **built-in MCP prompts** that guide Claude to organize findings into meaningful sections
- **lookup_domain_detailed** - Return a sample of 3 individual host records with services, ASN, geo, and TLS data, along with information about total available records and **structured MCP prompts** for comprehensive infrastructure analysis
- **lookup_ip** - Enrich an IP with DNS, ASN, service info, and TLS metadata
- **new_fqdns** - Find recently observed FQDNs for a domain (via DNS and certs)
- **host_services** - List open ports and service banners for a given domain or IP
- Make sure the target is publicly visible
- Check your API key and rate limits
- DNS-based results rely on recent Censys observations
- Scan a single domain or IP at a time for faster results
- Use lookup_domain or lookup_ip for focused data
- If you experience errors with result formatting, ensure you're using the latest version
- The tools handle pagination automatically - lookup_domain collects all available results, while lookup_domain_detailed shows a limited sample
- For domains with many results, queries may take longer to complete due to multiple API requests
- new_fqdns does not represent true "first seen" FQDNs; it filters by last observed timestamps
- This tool is intended for conversational, single-target analysis (not batch scans)
- lookup_domain_detailed only shows 3 records to keep responses manageable, even when more are available
- Censys Python SDK (https://github.com/censys/censys-python)

SECURITY
MCP 收录不等于安全审核
MCP 服务器可能获得模型上下文、凭据、本地文件或调用外部系统的权限。连接 Agent 前,请检查代码、环境变量、网络行为、软件包来源与维护状态。
