Signal Relay - SocioLogic MCP Server

A remote MCP (Model Context Protocol) server that connects AI agents to SocioLogic's synthetic persona platform. Interview realistic customer personas, run multi-persona research campaigns, and export board-ready reports—all through natural conversation.

Features

15 MCP Tools - Full access to personas, campaigns, focus groups, and credits
High-Fidelity Personas - Synthetic personas with consistent demographics, psychographics, and behavior
Semantic Memory - RAG-powered memory retrieval for persona continuity across conversations
Edge Deployed - Runs on Cloudflare Workers (300+ locations, <50ms latency)
Secure - API key authentication, request validation, no data stored on edge

Quick Start

Use the Hosted Server (Recommended)

The fastest way to get started is using our hosted server at https://mcp.sociologicai.com.

Get an API key at sociologic.ai/dashboard/api-keys (100 free credits on signup)
Configure your MCP client:

Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "sociologic": {
      "transport": "http",
      "url": "https://mcp.sociologicai.com",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}

Claude Code (.mcp.json in your project):

{
  "mcpServers": {
    "sociologic": {
      "transport": "http",
      "url": "https://mcp.sociologicai.com",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}

Start chatting! Ask Claude to interview personas, create campaigns, or explore the marketplace.
