AI agents call get_user_following to retrieve information from Twikit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves following data without modifying, deleting, or executing external operations. It is a standard Read category tool that fetches user relationship information. Severity is low because unauthorized access to public following lists, while a privacy/information disclosure concern, does not directly enable financial loss, code execution, or data destruction.
From the tool's definition Tool name 'get_user_following' indicates retrieval of a user's following list. No description provided, but the 'get_' prefix and verb 'following' clearly denote a read-only query operation.
Documented attack patterns abuse exactly the kind of access get_user_following gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Twikit, and nothing reaches the server without passing your rules. This is the rule we recommend for get_user_following:
{
"version": "1",
"default": "deny",
"tools": {
"get_user_following": {}
}
}get_user_following is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_user_following. It is categorised as a Read tool in the Twikit MCP Server, which means it retrieves data without modifying state.
Register the Twikit MCP server in PolicyLayer and add a rule for get_user_following: 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 Twikit. Nothing to install.
get_user_following 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 get_user_following 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 get_user_following. 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.
get_user_following is provided by the Twikit MCP server (tangivis/twitter-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Twikit, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
