Retrieve a specific post by its ID, including metadata and engagement counts.
AI agents call getPostsById to retrieve information from Xdevplatform/xmcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing data (a post and its metadata) without creating, modifying, deleting, or executing any operations. It is a straightforward read operation with no side effects. The low severity reflects minimal risk: an agent could query posts but cannot cause harm through data retrieval alone.
From the tool's definition The tool name is 'getPostsById' and the description states it will 'Retrieve a specific post by its ID, including metadata and engagement counts.' The use of 'Retrieve' and the read-only nature of fetching post data with no modification capabilities clearly…
Attacks that exploit this kind of access
Retrieve a specific post by its ID, including metadata and engagement counts. It is categorised as a Read tool in the Xdevplatform/xmcp MCP Server, which means it retrieves data without modifying state.
Register the Xdevplatform/x MCP server in PolicyLayer and add a rule for getPostsById: 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.
getPostsById is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the getPostsById 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 getPostsById. 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.
getPostsById 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.
getPostsById 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.
