Mark a release as completed within a pipeline. The target pipeline must already have a completed release stage configured.
AI agents use linear_completeRelease 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 modifies the state of a release record, which is a reversible operation (a release can theoretically be unmarked or transitioned back). It does not delete data (Destructive), execute arbitrary code (Execute), or move money (Financial). The action is localized to release state management within Linear's project management system.
From the tool's definition Tool description states 'Mark a release as completed' - this is a state modification operation that updates a release record from an incomplete to completed status.
Documented attack patterns abuse exactly the kind of access linear_completeRelease 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_completeRelease:
{
"version": "1",
"default": "deny",
"tools": {
"linear_completeRelease": {
"limits": [
{
"counter": "linear_completerelease_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}linear_completeRelease 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.

Mark a release as completed within a pipeline. The target pipeline must already have a completed release stage configured. 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_completeRelease: 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_completeRelease 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_completeRelease 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_completeRelease. 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_completeRelease 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.
