Retrieve a single message by ID, including its full content, subject line, and metadata.
AI agents call get_message 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 returns message data (content, subject, metadata) without modifying, executing, deleting, or creating anything. It is a read-only retrieval operation with no blast radius beyond potential information disclosure of existing messages.
From the tool's definition Tool name 'get_message' and description states 'Retrieve a single message by ID' — retrieves data without side effects.
Attacks that exploit this kind of access
Retrieve a single message by ID, including its full content, subject line, and metadata. 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_message: 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_message 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_message 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_message. 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_message 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.
