`name`	string	—	The new name of the project
`leadId`	string	—	The UUID of the user to set as project lead

RISK

Why update_project is rated Medium

This tool modifies an existing project rather than creating or deleting it. The change is reversible since updates can be undone through subsequent modifications. The severity is medium because unintended project updates could disrupt team workflows, visibility, or project settings, but the changes themselves are not irreversible.

From the tool's definition Tool name is 'update_project' and description states 'Update an existing Linear project' - both indicate modification of existing data (project configuration, settings, metadata, etc.).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_project safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Linear, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_project, this is the rule to start with:

update_project Rate-limited

update_project 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.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "update_project": {
      "limits": [
        {
          "counter": "update_project_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Linear, apply this rule, and every update_project call is checked against it from then on.
