AI agents call list_projects 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.
This tool queries and returns project information without modifying, deleting, or executing any operations. It is purely informational and poses minimal security risk in terms of misuse by an AI agent. The only concern would be information disclosure if project names or stats are sensitive, but the tool itself performs no destructive or harmful actions.
From the tool's definition Tool name 'list_projects' and description 'List all Flux projects with their stats' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_projects 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_projects:
{
"version": "1",
"default": "deny",
"tools": {
"list_projects": {}
}
}list_projects is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all Flux projects with their stats. 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_projects: 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_projects 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_projects 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_projects. 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_projects 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.
