get_users
AI agents call get_users to retrieve information from MCP Playground without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves user data from the SQLite database with no side effects. Despite the empty description lowering confidence slightly, the name and server context make it clear this is a data retrieval operation. Read operations on internal employee databases present minimal risk when the database contains non-sensitive organizational data.
From the tool's definition Tool name 'get_users' indicates data retrieval; sibling tool 'get_all_employee_profiles' and server description mentioning 'querying users' confirm this is a read-only query operation on the employee database.
Attacks that exploit this kind of access
get_users. It is categorised as a Read tool in the MCP Playground MCP Server, which means it retrieves data without modifying state.
Register the MCP Playground MCP server in PolicyLayer and add a rule for get_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 Playground. Nothing to install.
get_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 get_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 get_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.
get_users is provided by the MCP Playground MCP server (jaanlavaerts/mcp_playground). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
