Create .claude-plan.md in workspace root. Markdown with sections and task checklists.
AI agents use createPlan to create or update resources in Patchwork Os — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Patchwork Os environment.
The tool creates or modifies a markdown planning file in the workspace root directory. This is a write operation (creates or modifies data reversibly) rather than read-only, as it creates new files. However, it does not delete, overwrite existing data irreversibly, move money, or execute arbitrary code—it only produces a markdown document for planning purposes.
From the tool's definition Tool name and description: "Create .claude-plan.md in workspace root. Markdown with sections and task checklists." This performs creation and modification of a file (.claude-plan.md) within the workspace, which is a reversible write operation.

Documented attack patterns abuse exactly the kind of access createPlan gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Patchwork Os, and nothing reaches the server without passing your rules. This is the rule we recommend for createPlan:
{
"version": "1",
"default": "deny",
"tools": {
"createPlan": {
"limits": [
{
"counter": "createplan_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}createPlan 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 .claude-plan.md in workspace root. Markdown with sections and task checklists. It is categorised as a Write tool in the Patchwork Os MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Patchwork Os MCP server in PolicyLayer and add a rule for createPlan: 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 Patchwork Os. Nothing to install.
createPlan 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 createPlan 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 createPlan. 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.
createPlan is provided by the Patchwork Os MCP server (oolab-labs/patchwork-os). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Patchwork Os, 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.
