Creates a new epic in the Agile Development 2.0 module.
AI agents use create_epic to create or update resources in Snow — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Snow environment.
Creating an epic is a reversible write operation that adds a new record to the Agile Development module. While it modifies system state, the action is not destructive (can be deleted) nor does it trigger external operations or financial transactions.
From the tool's definition Tool name 'create_epic' and description explicitly states 'Creates a new epic in the Agile Development 2.0 module.' This is a creation operation that adds data to the system.
Documented attack patterns abuse exactly the kind of access create_epic gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Snow, and nothing reaches the server without passing your rules. This is the rule we recommend for create_epic:
{
"version": "1",
"default": "deny",
"tools": {
"create_epic": {
"limits": [
{
"counter": "create_epic_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_epic 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.

Creates a new epic in the Agile Development 2.0 module. It is categorised as a Write tool in the Snow MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Snow MCP server in PolicyLayer and add a rule for create_epic: 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 Snow. Nothing to install.
create_epic 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_epic 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_epic. 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_epic is provided by the Snow MCP server (shunyaai/snow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Snow, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
