Frequently asked questions

What does the Sonar MCP server do?

Read-only access to self-hosted SonarQube Community Build: issues, security hotspots, rules and code snippets so an agent can fix findings locally.

Is the Sonar MCP server free?

The server is free, but you will likely need an account. The server itself is free, but it connects to a service that needs an account or API key, which may have paid tiers. Check the provider for current pricing.

Does Sonar run locally or remotely?

Local. Runs on your machine (stdio). You install it with npx, uvx, Docker or from source.

How do I add Sonar to Claude Code?

Run: claude mcp add sonar -e SONAR_URL=... -e SONAR_TOKEN=... -- docker run -i --rm -e SONAR_URL -e SONAR_TOKEN ghcr.io/igorolv/sonar-mcp-server:0.1.0
