Adds a milestone or phase to ROADMAP.md. Creates a structured entry with title, description, target date, and deliverables.
AI agents use add_roadmap_milestone to create or update resources in Project MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Project MCP environment.
This tool creates or modifies project documentation (roadmap milestones) that can be edited or removed later, making it a Write operation rather than Destructive. The severity is medium because unauthorized roadmap changes could mislead project planning and stakeholder expectations, but the impact is typically reversible and scoped to documentation rather than core systems or financial decisions.
From the tool's definition Tool explicitly modifies ROADMAP.md by adding new milestone/phase entries with title, description, target date, and deliverables; the verb 'adds' and reference to 'creates a structured entry' indicate reversible data modification.
Documented attack patterns abuse exactly the kind of access add_roadmap_milestone gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Project MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for add_roadmap_milestone:
{
"version": "1",
"default": "deny",
"tools": {
"add_roadmap_milestone": {
"limits": [
{
"counter": "add_roadmap_milestone_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_roadmap_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.

Adds a milestone or phase to ROADMAP.md. Creates a structured entry with title, description, target date, and deliverables. It is categorised as a Write tool in the Project MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Project MCP server in PolicyLayer and add a rule for add_roadmap_milestone: 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 Project MCP. Nothing to install.
add_roadmap_milestone 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 add_roadmap_milestone 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 add_roadmap_milestone. 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.
add_roadmap_milestone is provided by the Project MCP server (pouyanafisi/project-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Project MCP, 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.
