Search for people/contacts in Apollo
AI agents call search_people to retrieve information from Apollo Io MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Search operations are categorized as Read per the classification rules. This tool queries Apollo's B2B database to retrieve prospect/contact information with no side effects, irreversible actions, code execution, or financial operations involved. The severity is low because misuse would only expose contact data already available through the Apollo platform, with limited blast radius for harm.
From the tool's definition Tool description states 'Search for people/contacts in Apollo' - a search operation that retrieves contact data without modifying, deleting, or executing operations.

Register the Apollo Io 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 Apollo Io 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.
