This is a practical MCP server but a community project, not officially released by SearXNG. It offers parallel search and multiple transport options with flexible configuration, but users should be aware of dependencies and potential risks.

SearXNG Mul MCP is a Model Context Protocol (MCP) server for integrating the SearXNG metasearch engine. It supports executing multiple search queries in parallel for improved efficiency and offers both stdio and HTTP transport protocols. The server integrates directly with the SearXNG REST API without browser automation, supports Basic Authentication, and can be deployed with Docker.

Tools

Executes one or more search queries with optional engines, categories, safesearch level, and language.

Setup

Ensure Node.js 18 or higher is installed.
Set SEARXNG_URL to your SearXNG instance.
Run with npx: SEARXNG_URL=https://your.searxng.com npx -y searxng-mul-mcp. Optionally set USERNAME and PASSWORD for Basic Auth, or use Docker.

Fit and risk

Best for

Developers building MCP clients or AI applications that need search functionality
Use cases requiring simultaneous queries of multiple search terms
Users wanting to use a custom or public SearXNG instance

Not for

Scenarios requiring browser automation or dynamic rendering of results
Production environments needing official support or commercial guarantees
Users with strict requirements for search API stability and maintenance

Required permissions

Access to SearXNG API, requiring a valid SEARXNG_URL
USERNAME and PASSWORD if SearXNG uses Basic Auth
Network access to communicate with the SearXNG server

Risks and side effects

Dependency on external SearXNG service, may be affected by network or service availability
No official support, with no guarantee of security or stability
Privacy risks when using public SearXNG instances, as queries may be logged

Troubleshooting

Check that SEARXNG_URL is correct and reachable
Verify USERNAME and PASSWORD are correct
In HTTP mode, check if the port is in use; change PORT environment variable if needed
Enable DEBUG=true to see detailed logs

Use cases

Quickly obtain results from multiple search engines in an AI assistant or client

Run parallel searches on multiple topics to save time

Integrate as an MCP server into applications supporting the MCP protocol
