Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "signal-relay": {
      "command": "npx",
      "args": [
        "-y",
        "signal-relay-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add --transport http signal-relay https://mcp.sociologic.ai --header 'X-API-Key: your-value'

Or run it on your computer

claude mcp add signal-relay -- npx -y signal-relay-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "signal-relay": {

Common questions

Is Signal Relay safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: X-API-Key

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.0.0) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

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

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):

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

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

"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.
