Signal Relay - SocioLogic MCP Server

![License: MIT](https://opensource.org/licenses/MIT) ![MCP](https://modelcontextprotocol.io)

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

24 MCP Tools - Personas, campaigns, focus groups, web research, RNG, credits, and payments
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.sociologic.ai.

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): ``json { "mcpServers": { "sociologic": { "transport": "http", "url": "https://mcp.sociologic.ai", "headers": { "X-API-Key": "YOUR_API_KEY" } } } } ``

Claude Code (.mcp.json in your project): ``json { "mcpServers": { "sociologic": { "transport": "http", "url": "https://mcp.sociologic.ai", "headers": { "X-API-Key": "YOUR_API_KEY" } } } } ``

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