AI agents call linear_getProjectUpdates 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 project updates without creating, modifying, or deleting any data. It is a straightforward read operation that queries existing information from the Linear system. The blast radius is minimal as it only exposes read access to project update history.
From the tool's definition Tool name is 'linear_getProjectUpdates' and description states 'Get all updates associated with a project' — both indicate retrieval of existing data with no modification or side effects.
Documented attack patterns abuse exactly the kind of access linear_getProjectUpdates 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_getProjectUpdates:
{
"version": "1",
"default": "deny",
"tools": {
"linear_getProjectUpdates": {}
}
}linear_getProjectUpdates is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get all updates associated with a project. It is categorised as a Read tool in the Linear MCP Server, which means it retrieves data without modifying state.
Register the Linear MCP server in PolicyLayer and add a rule for linear_getProjectUpdates: 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_getProjectUpdates 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_getProjectUpdates 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_getProjectUpdates. 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_getProjectUpdates 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.
