Get tweets from communities the authenticated user has joined (paginated).
AI agents call get_communities_timeline 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 existing tweet data from communities the user is a member of. It performs a read-only query operation with pagination support, consistent with the Read category definition of retrieving or querying data without side effects. There is no data creation, modification, deletion, code execution, or financial impact.
From the tool's definition Tool name 'get_communities_timeline' and description 'Get tweets from communities the authenticated user has joined (paginated)' — the verb 'Get' and the action of retrieving/fetching tweets indicate data retrieval with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get_communities_timeline 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_communities_timeline:
{
"version": "1",
"default": "deny",
"tools": {
"get_communities_timeline": {}
}
}get_communities_timeline is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get tweets from communities the authenticated user has joined (paginated). 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_communities_timeline: 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_communities_timeline 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_communities_timeline 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_communities_timeline. 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_communities_timeline 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.
