MCP Search

Containerized search and web scraping infrastructure powered by Model Context Protocol

Overview

MCP Search is a containerized infrastructure that provides web search and URL scraping capabilities through the Model Context Protocol (MCP). It combines SearXNG (privacy-respecting metasearch engine) and Firecrawl (web scraping API) with their respective MCP servers, backed by Redis, PostgreSQL, RabbitMQ, and Playwright.

Usage

Requirements

Dependency	Minimum Version
Docker or Podman (with compose)	23.0 / 5.0
Bash	5.0
OpenSSL	3.x

Quick Start

1. Clone the repository:

git clone https://github.com/Mournweiss/mcp-search.git
cd mcp-search

2. Run the build script:

chmod +x build.sh
./build.sh

The script will:

• Create .env from .env.example if it doesn't exist
• Sync missing variables from the template
• Generate secrets (SEARXNG_SECRET_KEY, POSTGRES_PASSWORD, etc.)
• Build and start all services in detached mode

Arguments

--podman, -p          Use podman-compose instead of docker-compose
--docker, -d          Use docker-compose explicitly
--foreground, -f      Run in foreground mode (attach logs)
--no-keygen, -n       Skip secret generation
--help, -h            Show help message

3. Connect to LLM:

   Both MCP servers run as streamable HTTP endpoints.

   Server	Endpoint	Transport
   mcp-searxng	http://localhost:30019/mcp	Streamable HTTP
   mcp-firecrawl	http://localhost:30028/mcp	Streamable HTTP

Environment Variables

All configuration is managed through .env. See .env.example for the full list of variables.

Primary variables:

Variable	Default	Description
PROJECT_NAME	mcp-search	Docker Compose project prefix
LOG_LEVEL	info	Global log level
SEARXNG_PORT	8080	SearXNG HTTP port
MCP_SEARXNG_PORT	30019	MCP SearXNG server port
FIRECRAWL_PORT	3000	Firecrawl API port
MCP_FIRECRAWL_PORT	30028	MCP Firecrawl server port
RABBITMQ_PORT	5672	RabbitMQ port
RABBITMQ_MANAGEMENT_PORT	15672	RabbitMQ management UI port
SEARXNG_ENGINES	google,duckduckgo,bing	Search engines to enable
SEARXNG_CATEGORIES	general,it,science	Search categories
