Retrieve the list of available email, SMS, and task messages in the account. Use this to find a message ID before sending.
AI agents call get_messages to retrieve information from Ontraport 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 and retrieves existing message data without creating, modifying, deleting, executing code, or triggering external operations. It is purely informational, used to discover message IDs for reference by other tools. The blast radius of misuse is minimal—an agent could enumerate messages but cannot alter them or cause harm through retrieval alone.
From the tool's definition Tool name is 'get_messages' and description states 'Retrieve the list of available email, SMS, and task messages in the account.' The verb 'retrieve' and action of listing available messages with no modification of data clearly indicates a read-only operation.
Attacks that exploit this kind of access
Retrieve the list of available email, SMS, and task messages in the account. Use this to find a message ID before sending. It is categorised as a Read tool in the Ontraport MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Ontraport MCP Server MCP server in PolicyLayer and add a rule for get_messages: 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 Ontraport MCP Server. Nothing to install.
get_messages 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_messages 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_messages. 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_messages is provided by the Ontraport MCP Server MCP server (landonray/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
