xo-protocol（XO 协议）

XO Protocol

The dating trust layer for AI agents. Verify identity, find compatible connections, check reputation, browse profiles and newsfeeds — all through a privacy-first API.

What You Can Do

Setup

1. Get an API key at xoxo.space/protocol
2. Install the MCP server:

git clone https://github.com/xo-protocol/xo-protocol.git
cd xo-protocol/examples
npm install @modelcontextprotocol/sdk

1. Add to your AI client config:

Claude Desktop (~/.claude/mcp_servers.json):

{
  "xo-protocol": {
    "command": "node",
    "args": ["/path/to/xo-protocol/examples/mcp-server.js"],
    "env": {
      "XO_API_KEY": "your-api-key",
      "XO_ACCESS_TOKEN": "your-jwt-token"
    }
  }
}

Example Workflows

"Am I verified?"

Call verify_identity → returns trust score, SBT status, and attestations.

"Find me someone compatible"

1. Call search_connections with optional limit
2. Get back compatibility scores + tmp_ids
3. Use tmp_id to call get_profile, get_reputation, or get_newsfeed for more detail

"What's this person like?"

1. Call get_profile with a tmp_id → interests, topics, preferences
2. Call get_newsfeed with the same tmp_id → their public posts
3. Summarize shared interests and conversation starters

"Is this person trustworthy?"

1. Call get_reputation → tier and score
2. Call get_social_signals → engagement quality and confidence
3. Flag if low engagement + high confidence (potential red flag)
