Dark Search Protocol

Runs a local search pipeline across many dark data sources and domains, exposing results to an assistant over stdio.

What you can do

Dark Search Protocol is a local MCP server distributed as the npm package dark-search-mcp-server and started with npx over stdio. Its description states it covers 161 dark data sources across 25 or more domains and runs a 6-step pipeline, and that it supports Streamable HTTP in addition to stdio. No individual tools are listed in the manifest, so the exact operations an assistant can call are not documented here.

When to use it

Consider it when an assistant needs to query sources that are not part of the ordinary indexed web and the user is willing to run a local process. It is a desktop-only server, so it is not usable from a browser-based client. Because the tool list is not published, verify the actual capabilities before relying on it.

Requirements

A local Node.js runtime able to run the npm package dark-search-mcp-server with npx, on a desktop machine. The manifest declares no authentication, no environment variables and no headers, so no credentials are documented as required. Network access is implied by the search function but is not stated.
