Search for people matching specific criteria
AI agents call search_people to retrieve information from People Data Labs MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a Read operation as it searches and retrieves person profile data from the People Data Labs database. It has no side effects (create, modify, delete).

Attacks that exploit this kind of access
Search for people matching specific criteria. It is categorised as a Read tool in the People Data Labs MCP Server MCP Server, which means it retrieves data without modifying state.
Register the People Data Labs MCP Server MCP server in PolicyLayer and add a rule for search_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 People Data Labs MCP Server. Nothing to install.
search_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 search_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 search_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.
search_people is provided by the People Data Labs MCP Server MCP server (phxdev1/peopledatalabs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
