Retrieve posts created by a specific user.
AI agents call getUsersPosts 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 (posts) without creating, modifying, deleting, or executing any operations. It is a standard read operation with minimal security risk. The low severity reflects that unauthorized access could expose user content, but the blast radius is limited to information disclosure rather than data destruction, financial impact, or code execution.
From the tool's definition Tool name 'getUsersPosts' and description 'Retrieve posts created by a specific user' indicate a query/retrieval operation with no data modification or side effects.
Attacks that exploit this kind of access
Retrieve posts created by a specific user. 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 getUsersPosts: 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.
getUsersPosts 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 getUsersPosts 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 getUsersPosts. 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.
getUsersPosts 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.
getUsersPosts 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.
