AI agents call get_member to retrieve information from Vaiz MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves member information from the workspace. It performs a query operation without creating, modifying, deleting, or executing anything. The action is read-only and has minimal security impact even if accessed by an unauthorized agent, as member information is typically non-sensitive organizational data.
From the tool's definition Tool name 'get_member' and description 'Get detailed information about a specific workspace member by ID' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Get detailed information about a specific workspace member by ID. It is categorised as a Read tool in the Vaiz MCP MCP Server, which means it retrieves data without modifying state.
Register the Vaiz MCP server in PolicyLayer and add a rule for get_member: 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 Vaiz MCP. Nothing to install.
get_member 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_member 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_member. 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_member is provided by the Vaiz MCP server (vaizcom/vaiz-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
