Remove a like from a previously liked post.
AI agents use unlikePost 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 modifies data by removing a like from a post, which is a reversible write operation. It does not delete the post itself, execute arbitrary code, move money, or perform destructive actions. The severity is medium because unauthorized use could affect user engagement metrics and social interactions, though the change can be easily reversed.
From the tool's definition Tool name is 'unlikePost' and description states 'Remove a like from a previously liked post' - this reverses a prior action (removing a like) which modifies user-generated state.
Attacks that exploit this kind of access
Remove a like from a previously liked post. 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 unlikePost: 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.
unlikePost 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 unlikePost 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 unlikePost. 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.
unlikePost 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.
unlikePost 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.
