Find people from Microsoft Graph directory data using query, alias, principal name, display name, department, office, and title filters.
AI agents call find_people to retrieve information from M365connector without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a directory search/query operation that retrieves existing data without creating, modifying, or deleting records. The filters indicate data retrieval only. However, severity is medium rather than low because directory data (names, departments, offices, titles) could expose organizational structure and individual information useful for social engineering or targeted attacks if an AI agent queries it…
From the tool's definition Tool searches and retrieves people data from Microsoft Graph directory using filters (query, alias, principal name, display name, department, office, title) with no modification capabilities described.
Attacks that exploit this kind of access
Find people from Microsoft Graph directory data using query, alias, principal name, display name, department, office, and title filters. It is categorised as a Read tool in the M365connector MCP Server, which means it retrieves data without modifying state.
Register the M365connector MCP server in PolicyLayer and add a rule for find_people: 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 M365connector. Nothing to install.
find_people 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 find_people 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 find_people. 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.
find_people is provided by the M365connector MCP server (m365connector). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
