Search for tweets matching a query and return results with engagement metrics
AI agents call search_tweets to retrieve information from Twitter Read without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries existing data (tweets matching a search query) and returns results with metrics. It has no side effects, does not modify or delete data, does not execute code or external operations, and does not involve financial transactions. It is purely a retrieval/query operation, which is the definition of the Read category.
From the tool's definition Tool name and description describe a search function that retrieves and returns tweet data with engagement metrics.
Attacks that exploit this kind of access
Search for tweets matching a query and return results with engagement metrics. It is categorised as a Read tool in the Twitter Read MCP Server, which means it retrieves data without modifying state.
Register the Twitter Read 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 Read. 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 Read MCP server (polsia-inc/twitter-read-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
