AI agents use linear_unarchiveInitiativeUpdate to create or update resources in Linear — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Linear environment.
This tool performs a write operation by changing the status of an archived initiative update back to an active/unarchived state. It is reversible (can be re-archived), making it Write rather than Destructive. The scope is limited to a single initiative update record, giving it medium severity rather than high. It does not delete data, execute code, involve financial transactions, or perform Read-only operations.
From the tool's definition Tool name and description indicate 'Restore an archived initiative update', which is a reversible state change operation that modifies data but does not permanently destroy it.
Documented attack patterns abuse exactly the kind of access linear_unarchiveInitiativeUpdate gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Linear, and nothing reaches the server without passing your rules. This is the rule we recommend for linear_unarchiveInitiativeUpdate:
{
"version": "1",
"default": "deny",
"tools": {
"linear_unarchiveInitiativeUpdate": {
"limits": [
{
"counter": "linear_unarchiveinitiativeupdate_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}linear_unarchiveInitiativeUpdate 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.
Restore an archived initiative update. It is categorised as a Write tool in the Linear MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Linear MCP server in PolicyLayer and add a rule for linear_unarchiveInitiativeUpdate: 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 Linear. Nothing to install.
linear_unarchiveInitiativeUpdate 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 linear_unarchiveInitiativeUpdate 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 linear_unarchiveInitiativeUpdate. 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.
linear_unarchiveInitiativeUpdate is provided by the Linear MCP server (tacticlaunch/mcp-linear). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
