Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.

How to run each
SonarQube MCP Server As a local MCP server: Docker image
claude mcp add --env "SONARQUBE_ORG=<YOUR_SONARQUBE_ORG>" --env "SONARQUBE_TOKEN=<YOUR_SONARQUBE_TOKEN>" --env "SONARQUBE_URL=<YOUR_SONARQUBE_URL>" --transport stdio sonarqube-mcp-server -- docker run -i --rm -e SONARQUBE_ORG -e SONARQUBE_TOKEN -e SONARQUBE_URL docker.io/sonarsource/sonarqube-mcpRequires: SONARQUBE_ORG (secret), SONARQUBE_TOKEN (secret), SONARQUBE_URL (secret)
io.github.machinegrade/validate As a remote MCP server
claude mcp add --transport http validate https://api.machinegrade.dev/mcpRequires: SANDBOX_API_KEY (secret)
Commands built only from what the marketplaces declare; the full set for every client is on each card.
Tools each declares
The marketplaces of io.github.machinegrade/validate publish no list of tools, so we do not compare tools.
Settings each asks for
Only SonarQube MCP Server asks for
SONARQUBE_ORG (secret)SONARQUBE_TOKEN (secret)SONARQUBE_URL (secret)
Only io.github.machinegrade/validate asks for
SANDBOX_API_KEY (secret)SANDBOX_URL
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
