AI agents use create_project to create or update resources in Flux MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Flux MCP Server environment.
Creating a new project is a reversible write operation that adds data to the system. It is not destructive (cannot be undone by design), not financial, and not code execution. The severity is medium because creating projects could impact team organization and collaboration structures, but the blast radius is limited as projects can typically be deleted and the operation itself is non-destructive.
From the tool's definition Tool is described as 'Create a new Flux project', which creates a new data structure in the Kanban board system.
Documented attack patterns abuse exactly the kind of access create_project 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 create_project:
{
"version": "1",
"default": "deny",
"tools": {
"create_project": {
"limits": [
{
"counter": "create_project_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_project stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a new Flux project. It is categorised as a Write tool in the Flux MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Flux MCP Server MCP server in PolicyLayer and add a rule for create_project: 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.
create_project is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_project 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 create_project. 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.
create_project 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.
