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)
  • Model Context Protocol (https://modelcontextprotocol.io/)
  • Claude Desktop (https://www.anthropic.com)

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。
