AI agents call list_tasks to retrieve information from Flux MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a query operation that retrieves task information from a Kanban board. It does not create, modify, delete, execute code, or commit financial transactions. The 'list' action is a fundamental Read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name is 'list_tasks' and description states 'List all tasks in a project with their blocked status' — this retrieves/queries data with no side effects.
Documented attack patterns abuse exactly the kind of access list_tasks gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Flux MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_tasks:
{
"version": "1",
"default": "deny",
"tools": {
"list_tasks": {}
}
}list_tasks is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all tasks in a project with their blocked status. It is categorised as a Read tool in the Flux MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Flux MCP Server MCP server in PolicyLayer and add a rule for list_tasks: 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 Flux MCP Server. Nothing to install.
list_tasks 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_tasks 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_tasks. 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_tasks is provided by the Flux MCP Server MCP server (sirsjg/flux). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
