WhisperGraph MCP: query the internet's infrastructure graph

WhisperGraph maps the internet's infrastructure as a graph of 46 billion nodes and edges, built for AI agents to query. Its MCP server puts that graph within reach of your AI app. ContextGate connects it to Claude, ChatGPT and Cursor, and every graph query is kept in Activity, which helps when an investigation has to be retraced later.

Add WhisperGraph to your AI app through ContextGate

  1. 1Click Connect WhisperGraph free and sign in with your Whisper Security account.

  3. 3Add ContextGate to your AI app as a connector or MCP server. The steps for each app are on the Works with page.
  4. 4Ask your AI app what WhisperGraph connects to a domain you're investigating, then open Activity to see the query.

Infrastructure research from your AI app

  • Query WhisperGraph's 46 billion nodes and edges of internet infrastructure from Claude or ChatGPT.
  • Follow connections between pieces of infrastructure during an investigation without leaving your chat.
  • Try it on WhisperGraph's free trial, which Whisper says takes two HTTP calls to start.

A trail for every lookup

  • Activity keeps a record of every WhisperGraph query, so you can retrace an investigation step by step.
  • Policies check each call and can block an internal hostname or secret from going out in a query.
  • Switch off any WhisperGraph tool you don't use; it's hidden and refused.

What you get with WhisperGraph and ContextGate

  • Your AI apps can use WhisperGraphClaude, Cursor, ChatGPT and other AI apps reach WhisperGraph through the one ContextGate connection you add to them.
  • You choose which tools they can useSwitch off any WhisperGraph tool you don't want used. It's hidden from your AI apps and refused if called.
  • Every call is checked and recordedYour policies check each call (for example, personal data is hidden and secrets are blocked), and Activity keeps a record of it.

ContextGate sees only the tool calls that go through it, not your AI app's built-in tools or your chats.
