AI agents use linear_createRelease 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 entity within Linear's release pipeline, which is a reversible data modification. It does not execute external deployments, delete data, or move financial resources. While releases may have operational significance, the tool itself only creates metadata/records in the project management system.
From the tool's definition Tool name 'linear_createRelease' and description 'Create a new release in a release pipeline' indicate data creation. The verb 'Create' and the action of adding a new release object to a system are characteristic of Write operations.
Documented attack patterns abuse exactly the kind of access linear_createRelease 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_createRelease:
{
"version": "1",
"default": "deny",
"tools": {
"linear_createRelease": {
"limits": [
{
"counter": "linear_createrelease_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}linear_createRelease 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.

Create a new release in a release 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_createRelease: 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_createRelease 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_createRelease 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_createRelease. 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_createRelease 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.
