Jenkins MCP Server Plugin 0.84.v50ca 24ef83f2 and earlier does not perform permission checks in several MCP tools.

This allows to do the following:

• Attackers with Item/Read permission can obtain information about the configured SCM in a job despite lacking Item/Extended Read permission (getJobScm).
• Attackers with Item/Read permission can trigger new builds of a job despite lacking Item/Build permission (triggerBuild).
• Attackers without Overall/Read permission can retrieve the names of configured clouds (getStatus).

MCP Server Plugin 0.86.v7d3355e6a a 18 performs permission checks for the affected MCP tools.
