SonarCloud MCP Server

An MCP server that provides tools for fetching SonarCloud issues related to pull requests.

Example prompt:

Fetch the list of OPEN or ACCEPTED issues from sonarcloud for this PR, which are assigned to __me__, fix them and push the changes to this PR.

Emphasis on the __me__ part, which is a special value in the sonarcloud API to reference the current user (token owner). You can stick this in your .claude/tools folder as sonarcloud-issues.md to have a shortcut which requests claude code to fetch and fix issues from SonarCloud.

Features

Supports authentication via API token
Returns formatted issue data with severity, type, and location information
