Look up a contact/handle by phone number or email and return conversation stats.
AI agents call get_contact_info to retrieve information from iMessage MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries contact information and conversation statistics from the local messages database without creating, modifying, deleting, or executing any operations. It is a straightforward lookup/retrieval function with no side effects, placing it firmly in the Read category.
From the tool's definition Tool description states 'Look up a contact/handle' and 'return conversation stats' — purely information retrieval operations with no modification or execution of commands.
Attacks that exploit this kind of access

Register the iMessage MCP Server MCP server in PolicyLayer and add a rule for get_contact_info: 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 iMessage MCP Server. Nothing to install.
get_contact_info 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_contact_info 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_contact_info. 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_contact_info is provided by the iMessage MCP Server MCP server (viraatdas/imessage-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
