Create a new phase in an Autotask project
AI agents use autotask_create_phase to create or update resources in Autotask — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Autotask environment.
This tool creates a new project phase, which is a reversible write operation. It modifies project data but does not delete, execute arbitrary code, or move money. The blast radius is medium because incorrect phase creation could disrupt project planning and team workflows, but the action is reversible through deletion or modification.
From the tool's definition Tool name 'autotask_create_phase' and description 'Create a new phase in an Autotask project' both indicate a create operation that modifies project structure.
Documented attack patterns abuse exactly the kind of access autotask_create_phase gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Autotask, and nothing reaches the server without passing your rules. This is the rule we recommend for autotask_create_phase:
{
"version": "1",
"default": "deny",
"tools": {
"autotask_create_phase": {
"limits": [
{
"counter": "autotask_create_phase_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}autotask_create_phase 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.

Create a new phase in an Autotask project. It is categorised as a Write tool in the Autotask MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Autotask MCP server in PolicyLayer and add a rule for autotask_create_phase: 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 Autotask. Nothing to install.
autotask_create_phase 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 autotask_create_phase 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 autotask_create_phase. 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.
autotask_create_phase is provided by the Autotask MCP server (wyre-technology/autotask-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Autotask, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
