WHAT IT DOES

What createPosts does on Xdevplatform/xmcp

AI agents use createPosts 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 createPosts is rated Medium

This tool creates and publishes new content (posts/tweets) which is a reversible write operation. It modifies data on the platform by adding new posts but does not irreversibly delete data (not Destructive), execute arbitrary code (not Execute), or involve financial transactions (not Financial).

From the tool's definition Tool name 'createPosts' and description 'Create and publish a new post (tweet), including replies, quotes, and polls' explicitly indicate creation and publication of content.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs createPosts 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 createPosts, this is the rule to start with:

createPosts Rate-limited

createPosts 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.

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