AI agents use attach_license_terms to create or update resources in Story SDK MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Story SDK MCP Server environment.
The tool modifies license terms (write operation), which affects IP assets and potentially revenue streams. While not destructive (reversible) or directly financial, it shapes licensing agreements that govern financial outcomes, making it high-severity if misused by an AI agent without proper authorization or context.
From the tool's definition Tool name 'attach_license_terms' on a licensing/IP management server; sibling tools include 'get_license_terms' and financial operations like 'claim_all_revenue', 'deposit_wip', suggesting this tool modifies license configurations.
Documented attack patterns abuse exactly the kind of access attach_license_terms gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Story SDK MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for attach_license_terms:
{
"version": "1",
"default": "deny",
"tools": {
"attach_license_terms": {
"limits": [
{
"counter": "attach_license_terms_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}attach_license_terms 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.

attach_license_terms. It is categorised as a Write tool in the Story SDK MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Story SDK MCP Server MCP server in PolicyLayer and add a rule for attach_license_terms: 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 Story SDK MCP Server. Nothing to install.
attach_license_terms 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 attach_license_terms 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 attach_license_terms. 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.
attach_license_terms is provided by the Story SDK MCP Server MCP server (piplabs/story-mcp-hub). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Story SDK MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
