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

Fetch issues from SonarCloud for specific pull requests
Filter by organization, project, and PR number
Supports authentication via API token
Returns formatted issue data with severity, type, and location information
