Target Reference Server
Whisper Overview
The whisper MCP server gives agents access to Whisper identity verification, RDAP lookups, security-graph analysis, and agent networking. It can run locally through the `whisper mcp` command or remotely at `https://whisper.online/mcp` over streamable HTTP. Keyless access exposes selected verification and graph tools, while an API key adds agent provisioning, governance, and submission capabilities. Reach for it when an agent needs a routable IPv6 identity, verified egress, or Whisper security data rather than speech transcription.
Primary Use Cases for Whisper:
- Verify an agent’s IPv6 identity before allowing communication
- Look up public RDAP records for routable IPv6 addresses
- Assess domains, IPs, ASNs, or file hashes from an AI client
- Route agent commands through a dedicated Whisper IPv6 egress
