Get the parameter definitions of a Jenkins job
AI agents call get_item_parameters 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 tool retrieves configuration metadata from Jenkins. It reads parameter definitions of a job, which is a passive query operation. There are no code execution, data modification, deletion, or financial consequences. The blast radius of misuse is minimal—an attacker gains only visibility into what parameters a job accepts, not the ability to trigger builds, modify jobs, or access sensitive secrets.
From the tool's definition Tool name 'get_item_parameters' and description 'Get the parameter definitions of a Jenkins job' indicate a retrieval operation with no side effects. It queries and returns metadata about job parameters without modifying, executing, or deleting any data.
Attacks that exploit this kind of access
Get the parameter definitions of a Jenkins job. 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_item_parameters: 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_item_parameters 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_item_parameters 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_item_parameters. 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_item_parameters 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.
