AI agents use linear_createReleaseStage 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 creates a new release stage, which is a data modification operation that can be undone (e.g., by deleting or archiving the stage). It does not execute arbitrary code, delete data irreversibly, or involve financial transactions. The blast radius is limited to project pipeline configuration within a single Linear workspace.
From the tool's definition Tool name contains 'create' and description states 'Create a new release stage in a pipeline', indicating reversible creation of a new resource within Linear's project management system.
Documented attack patterns abuse exactly the kind of access linear_createReleaseStage 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_createReleaseStage:
{
"version": "1",
"default": "deny",
"tools": {
"linear_createReleaseStage": {
"limits": [
{
"counter": "linear_createreleasestage_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}linear_createReleaseStage 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.
Create a new release stage in a pipeline. 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_createReleaseStage: 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_createReleaseStage 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_createReleaseStage 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_createReleaseStage. 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_createReleaseStage 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.
