Retrieve the full list of tags defined in the account. Use this to look up tag IDs or verify tag names before applying them.
AI agents call list_tags 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 only queries and returns existing tag data without creating, modifying, deleting, or executing any operations. It has no side effects and poses minimal security risk—the worst case is information disclosure about tag definitions already in the account, which is low-impact read access.
From the tool's definition Tool description states 'Retrieve the full list of tags defined in the account' with purpose to 'look up tag IDs or verify tag names'. The verb 'Retrieve' and lack of any modification language clearly indicates a read-only query operation.
Attacks that exploit this kind of access
Retrieve the full list of tags defined in the account. Use this to look up tag IDs or verify tag names before applying them. 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 list_tags: 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.
list_tags 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 list_tags 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 list_tags. 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.
list_tags 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.
