AI agents call linear_getTeams to retrieve information from Linear without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves team information from a Linear workspace without making any changes to data or triggering external operations. It is a straightforward read operation with minimal blast radius if misused—worst case, an AI agent could retrieve organizational team information, which poses no data loss or financial risk.
From the tool's definition Tool name 'linear_getTeams' and description 'Get a list of teams from Linear' indicate data retrieval with no modification. The verb 'Get' and absence of any destructive, write, or execute operations confirm this is a read-only query.
Documented attack patterns abuse exactly the kind of access linear_getTeams 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_getTeams:
{
"version": "1",
"default": "deny",
"tools": {
"linear_getTeams": {}
}
}linear_getTeams is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Linear MCP server in PolicyLayer and add a rule for linear_getTeams: 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_getTeams is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the linear_getTeams 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_getTeams. 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_getTeams 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.
