list_taskruns
AI agents call list_taskruns to retrieve information from Lumino MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list' prefix explicitly indicates data retrieval without modification or execution. In the context of a Kubernetes debugging and observability server (Lumino MCP), this tool almost certainly queries TaskRun status and metadata. No side effects or data mutations are implied.
From the tool's definition Tool name 'list_taskruns' uses the verb 'list', which retrieves or queries data about Tekton TaskRuns. The description is empty, but the naming convention strongly indicates a read-only operation typical of observability/debugging tools in this Kubernetes SRE…
Attacks that exploit this kind of access
list_taskruns. It is categorised as a Read tool in the Lumino MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Lumino MCP Server MCP server in PolicyLayer and add a rule for list_taskruns: 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 Lumino MCP Server. Nothing to install.
list_taskruns 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 list_taskruns 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 list_taskruns. 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.
list_taskruns is provided by the Lumino MCP Server MCP server (lumino-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
