Search through user profiles using a simple text query
AI agents call search_users to retrieve information from MCP User Profile Management Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query operation on existing user profile data and returns results without creating, modifying, deleting, or executing any side effects. It is a standard read operation with minimal security risk, assuming appropriate access controls are in place.
From the tool's definition Tool name 'search_users' and description 'Search through user profiles using a simple text query' indicates a retrieval operation with no modification or deletion of data.

Search through user profiles using a simple text query. It is categorised as a Read tool in the MCP User Profile Management Server MCP Server, which means it retrieves data without modifying state.
Register the MCP User Profile Management Server MCP server in PolicyLayer and add a rule for search_users: 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 MCP User Profile Management Server. Nothing to install.
search_users 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_users 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_users. 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_users is provided by the MCP User Profile Management Server MCP server (sldragon/mcp-elicitation-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
