Search for tweets by hashtag or keyword
AI agents call search_tweets to retrieve information from Twitter without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves publicly available tweet data based on search criteria. It has no side effects on the Twitter platform or user accounts—it only reads and returns matching tweets. The blast radius of misuse is minimal; an AI agent could only retrieve data it should not have access to, not modify or delete content.
From the tool's definition Tool description explicitly states 'Search for tweets by hashtag or keyword' with no mention of modification, deletion, or execution capabilities.
Documented attack patterns abuse exactly the kind of access search_tweets gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Twitter, and nothing reaches the server without passing your rules. This is the rule we recommend for search_tweets:
{
"version": "1",
"default": "deny",
"tools": {
"search_tweets": {}
}
}search_tweets is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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