AI agents call ado_search_users to retrieve information from Mcp Azure without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure data retrieval function that queries user information in Azure DevOps. It has no side effects and only returns identity data needed for reference in other operations. The search functionality and return-only nature classify it as a Read operation with low severity due to minimal blast radius if misused.
From the tool's definition Tool description states it 'Busca usuarios' (searches users) and 'Devuelve' (returns) user identity information.

Register the Mcp Azure MCP server in PolicyLayer and add a rule for ado_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 Azure. Nothing to install.
ado_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 ado_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 ado_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.
ado_search_users is provided by the Mcp Azure MCP server (soulberto/mcp-azure). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
