Create a community note on a post to add context or fact-checking information.
AI agents use createCommunityNotes 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.
This tool creates new data (community notes) that can provide context or fact-checking on posts. It is reversible (notes can typically be edited or removed), making it Write rather than Destructive. The severity is medium because malicious misuse could spread misinformation or spam community notes, but the impact is limited to note creation rather than account compromise or financial harm.
From the tool's definition Tool name 'createCommunityNotes' and description 'Create a community note on a post' indicate a create/write operation that adds content to a platform.
Attacks that exploit this kind of access
Create a community note on a post to add context or fact-checking information. 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.
Register the Xdevplatform/x MCP server in PolicyLayer and add a rule for createCommunityNotes: 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.
createCommunityNotes 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 createCommunityNotes 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 createCommunityNotes. 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.
createCommunityNotes 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.
createCommunityNotes is one line of Xdevplatform/x's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
