WHAT IT DOES

What linear_create_milestone does on Allmcp

AI agents use linear_create_milestone to create or update resources in Allmcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Allmcp environment.

RISK

Why linear_create_milestone is rated Medium

Creating a milestone in Linear is a reversible write operation that modifies project/workspace data. It does not execute arbitrary code, delete data, or move money. The confidence is slightly reduced (0.85 rather than 0.95) because the description is empty, leaving some ambiguity about the exact scope and whether there are side effects beyond simple milestone creation.

From the tool's definition Tool name 'linear_create_milestone' indicates creation of a milestone object in Linear (issue tracking system). The 'create' verb matches the Write category definition: 'creates or modifies data reversibly'.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs linear_create_milestone safely

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

linear_create_milestone Rate-limited

linear_create_milestone 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.
