# 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 | Tool | What It Does | |------|-------------| | `verify_identity` | Check if someone is a verified real person (SBT, trust score) | | `search_connections` | Find compatible people with AI-scored matching | | `get_reputation` | Get reputation tier (novice → S) and score | | `get_social_signals` | Get conversation quality score | | `get_profile` | See a user's shared interests and preferences | | `get_newsfeed` | Browse a connection's public posts | ## Setup 1. Get an API key at [xoxo.space/protocol](https://xoxo.space/en/protocol) 2. Install the MCP server: ```bash git clone https://github.com/xo-protocol/xo-protocol.git cd xo-protocol/examples npm install @modelcontextprotocol/sdk ``` 3. Add to your AI client config: **Claude Desktop** (`~/.claude/mcp_servers.json`): ```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) ## Privacy Rules - All data requires the user's explicit OAuth authorization - No real names, photos, or location in any response - User IDs are ephemeral (24h expiry) — no long-term tracking - Each tool only accesses the scopes the user approved ## Links - [API Docs](https://protocol.xoxo.space/protocol/docs) - [OpenAPI Spec](https://github.com/xo-protocol/xo-protocol/blob/main/openapi.yaml) - [SDK](https://github.com/xo-protocol/xo-protocol/tree/main/sdk)
