WHAT IT DOES

What createLists does on Xdevplatform/xmcp

AI agents use createLists to create or update resources in Xdevplatform/xmcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Xdevplatform/xmcp environment.

RISK

Why createLists is rated Medium

This tool creates new lists (a data structure), which is a write operation. The creation is reversible (lists can be deleted), so it does not fall into the Destructive category. The tool does not execute arbitrary code, move money, or retrieve data, making Write the appropriate classification.

From the tool's definition Tool name 'createLists' and description 'Create a new public or private list' indicate data creation with reversible effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs createLists safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Xdevplatform/xmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For createLists, this is the rule to start with:

createLists Rate-limited

createLists 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.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Xdevplatform/xmcp, apply this rule, and every createLists call is checked against it from then on.

FAQ

Questions about createLists

What does the createLists tool do? +

Create a new public or private list. It is categorised as a Write tool in the Xdevplatform/xmcp MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on createLists? +

Register the Xdevplatform/x MCP server in PolicyLayer and add a rule for createLists: 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 Xdevplatform/xmcp. Nothing to install.

What risk level is createLists? +

createLists is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit createLists? +

Yes. Add a rate_limit block to the createLists 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.

How do I block createLists completely? +

Set action: deny in the PolicyLayer policy for createLists. 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.

What MCP server provides createLists? +

createLists is provided by the Xdevplatform/x MCP server (xdevplatform/xmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
