Finalize the plan: submit collected answers to generate AI prompt and project docs (plan.md, pmpt.md, pmpt.ai.md). Call pmpt_plan_questions first to get the questions, ask the user conversationally, then call this with the answers.
AI agents use pmpt_plan to create or update resources in Pmpt — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pmpt environment.
pmpt_plan creates and modifies project documentation files, which is a Write operation. It doesn't delete or overwrite existing data irreversibly, doesn't execute arbitrary code, and doesn't involve financial transactions.
From the tool's definition Tool description states it 'submit collected answers to generate AI prompt and project docs (plan.md, pmpt.md, pmpt.ai.md)' — the action creates multiple new files/documents.
Documented attack patterns abuse exactly the kind of access pmpt_plan gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Pmpt, and nothing reaches the server without passing your rules. This is the rule we recommend for pmpt_plan:
{
"version": "1",
"default": "deny",
"tools": {
"pmpt_plan": {
"limits": [
{
"counter": "pmpt_plan_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}pmpt_plan 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.

Finalize the plan: submit collected answers to generate AI prompt and project docs (plan.md, pmpt.md, pmpt.ai.md). Call pmpt_plan_questions first to get the questions, ask the user conversationally, then call this with the answers. It is categorised as a Write tool in the Pmpt MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Pmpt MCP server in PolicyLayer and add a rule for pmpt_plan: 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 Pmpt. Nothing to install.
pmpt_plan 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 pmpt_plan 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 pmpt_plan. 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.
pmpt_plan is provided by the Pmpt MCP server (pmptwiki/pmpt-cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Pmpt, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
