MCP-searxng
MCP server that exposes a single tool to perform web searches through a configured searXNG instance (default http://localhost:8080 via SEARXNG_URL).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
The MCP wrapper itself has no documented auth/authorization and exposes a simple search capability. Security largely depends on how searXNG is configured (TLS, authentication, and rate limiting). README suggests SEARXNG_URL default is http://localhost:8080 (not TLS), and provides no guidance about sanitizing logs, handling upstream errors, or restricting the MCP server’s network exposure.
⚡ Reliability
Best When
You have (or control) a searXNG instance you trust and want a lightweight MCP wrapper for basic search.
Avoid When
You need strong authentication/authorization for search operations, detailed error/rate-limit semantics, or you cannot control the security posture of the upstream searXNG endpoint.
Use Cases
- • Enable LLM agents to perform live web search via MCP
- • Route agent search requests through an existing self-hosted searXNG deployment
- • Provide a simple search tool interface for agentic workflows
Not For
- • Production use without validating searXNG security, authentication, and rate-limiting
- • Use cases requiring authenticated, scoped user access to search results
- • Environments requiring strict compliance controls over where queries/results are sent
Interface
Authentication
No authentication mechanisms are described for the MCP server. Upstream searXNG authentication (if any) is not documented in this README.
Pricing
Open-source package; costs depend on your searXNG hosting and any infrastructure you run.
Agent Metadata
Known Gotchas
- ⚠ Single tool described; no guidance on query formatting, result size limits, or failure modes
- ⚠ Relies on SEARXNG_URL; if upstream searXNG is slow/unreachable, agent behavior may degrade without documented retry/backoff
- ⚠ No documented rate-limit handling for the MCP layer
