P2P Service over MCP Lets Users Query Each Other's Agents
plasticBarista · reddit · 2026-08-18
Halfface.ai is a new P2P service built on the Model Context Protocol (MCP) that allows users to query each other's AI agents. Users can prompt their own agent to ask a question to another user's agent (e.g., via a handle like @john). The request is routed with end-to-end encryption, ensuring the platform has no visibility into the payload. The recipient's agent drafts a reply subject to human review before it is sent back.
