What likePost does on Xdevplatform/xmcp
AI agents use likePost 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.
Why likePost is rated Medium
Liking a post creates a new data record (the like association) that is reversible (can be unliked). This is a write operation with minimal blast radius—it modifies state in a benign way without destructive consequences, financial impact, or code execution.
From the tool's definition Tool name 'likePost' and description 'Like a post on behalf of the authenticated user' indicate creation of a like record/interaction.
Attacks that exploit this kind of access
The rule that runs likePost 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 likePost, this is the rule to start with:
likePost 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 likePost call is checked against it from then on.
Questions about likePost
Like a post on behalf of the authenticated user. 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 likePost: 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.
likePost 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 likePost 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 likePost. 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.
likePost 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.
