Install Sonar MCP Server in Claude Code

What you need first

• Claude Code, installed.
• Docker, which gives the docker command the server starts with.
• Your own values for YOUR_SONAR_URL,YOUR_SONAR_TOKEN.

Steps

1. Run this in a terminal, in the project folder. It adds the server for you in that project; put --scope user after claude mcp add to have it in every project.

claude mcp add --env SONAR_URL=YOUR_SONAR_URL --env SONAR_TOKEN=YOUR_SONAR_TOKEN --transport stdio sonar-mcp-server -- docker run -i --rm -e SONAR_URL -e SONAR_TOKEN ghcr.io/igorolv/sonar-mcp-server:0.1.0

2. Replace YOUR_SONAR_URL,YOUR_SONAR_TOKEN with your own values.
3. Start Claude Code and type /mcp: the server is listed with its state.

Check it worked

Ask Claude Code: List the tools of sonar-mcp-server.

If it does not start

Cannot connect to the Docker daemon

Docker is not running. Start it, then restart Claude Code.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.
