Signal Relay - SocioLogic MCP Server

License: MIT MCP

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.

  1. Get an API key at sociologic.ai/dashboard/api-keys (100 free credits on signup)

  2. 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"
      }
    }
  }
}
  1. Start chatting! Ask Claude to interview personas, create campaigns, or explore the marketplace.

Configuration

Environment Variables

VariableDescriptionDefault
SOCIOLOGIC_API_URLBackend API URLhttps://www.sociologic.ai

wrangler.toml

[vars]
SOCIOLOGIC_API_URL = "https://www.sociologic.ai"

Security

  • API keys are passed via X-API-Key header or Authorization: Bearer header
  • Request size limited to 1MB to prevent DoS
  • Input validation via Zod schemas on all tool parameters
  • No data stored on edge - all data flows through to the SocioLogic API

Rate Limiting

For production deployments, we recommend enabling Cloudflare's rate limiting:

  1. Go to Cloudflare Dashboard > Security > WAF > Rate limiting rules
  2. Create a rule: 100 requests per 10 seconds per IP
