Retrieve lists followed by a specific user.
AI agents call getUsersFollowedLists 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 is a straightforward query operation that fetches information about which lists a user follows. It retrieves data (Read category) with no capacity to modify, delete, or execute operations. The blast radius is minimal as it only exposes follow list metadata for a user.
From the tool's definition Tool name 'getUsersFollowedLists' and description 'Retrieve lists followed by a specific user' indicate data retrieval without modification or side effects.
Attacks that exploit this kind of access
Retrieve lists followed 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 getUsersFollowedLists: 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.
getUsersFollowedLists 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 getUsersFollowedLists 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 getUsersFollowedLists. 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.
getUsersFollowedLists 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.
getUsersFollowedLists 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.
