AI agents use storybloq_node_add to create or update resources in Storybloq — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Storybloq environment.
This tool creates or modifies project configuration by adding a federation node. This is a Write operation because it creates new infrastructure elements within the project context. Severity is medium because misconfiguration of federation nodes could disrupt project orchestration or cause operational issues, but the action is reversible (nodes can be removed).
From the tool's definition Tool description states 'Add a federation node to an orchestrator project', indicating creation/modification of project infrastructure configuration.
Documented attack patterns abuse exactly the kind of access storybloq_node_add gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Storybloq, and nothing reaches the server without passing your rules. This is the rule we recommend for storybloq_node_add:
{
"version": "1",
"default": "deny",
"tools": {
"storybloq_node_add": {
"limits": [
{
"counter": "storybloq_node_add_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}storybloq_node_add 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.
Free to start. No card required.
Add a federation node to an orchestrator project. It is categorised as a Write tool in the Storybloq MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Storybloq MCP server in PolicyLayer and add a rule for storybloq_node_add: 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 Storybloq. Nothing to install.
storybloq_node_add 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 storybloq_node_add 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 storybloq_node_add. 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.
storybloq_node_add is provided by the Storybloq MCP server (storybloq/storybloq). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
