AI agents use create_phase to create or update resources in Zoho Projects MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Zoho Projects MCP Server environment.
Creating a phase/milestone is a reversible write operation that modifies project structure by adding new organizational elements. It does not delete, execute arbitrary code, or move money. The medium severity reflects that misuse could disrupt project planning but changes can be undone by deletion.
From the tool's definition Tool name 'create_phase' and description 'Create a new phase/milestone' indicate a create operation that adds new data to the project management system.
Documented attack patterns abuse exactly the kind of access create_phase gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Zoho Projects MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_phase:
{
"version": "1",
"default": "deny",
"tools": {
"create_phase": {
"limits": [
{
"counter": "create_phase_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}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/milestone. It is categorised as a Write tool in the Zoho Projects MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Zoho Projects MCP Server MCP server in PolicyLayer and add a rule for 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 Zoho Projects MCP Server. Nothing to install.
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 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 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.
create_phase is provided by the Zoho Projects MCP Server MCP server (qpiai/zoho-projects-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Zoho Projects MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
