Get all installed plugins from Jenkins
AI agents call get_all_plugins to retrieve information from Mcp Jenkins without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only query that retrieves metadata about installed Jenkins plugins. While it does not modify data, the severity is elevated from 'low' to 'medium' because plugin information can reveal sensitive infrastructure details (versions, capabilities, potential vulnerabilities) that an attacker could use to identify and exploit weaknesses in the Jenkins environment.
From the tool's definition Tool name 'get_all_plugins' and description 'Get all installed plugins from Jenkins' clearly indicate a retrieval operation with no modification or execution. No side effects.
Attacks that exploit this kind of access
Get all installed plugins from Jenkins. It is categorised as a Read tool in the Mcp Jenkins MCP Server, which means it retrieves data without modifying state.
Register the Mcp Jenkins MCP server in PolicyLayer and add a rule for get_all_plugins: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Jenkins. Nothing to install.
get_all_plugins is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_all_plugins rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_all_plugins. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_all_plugins is provided by the Mcp Jenkins MCP server (lanbaoshen/mcp-jenkins). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
