List all available personality types with descriptions
AI agents call list_personalities to retrieve information from Second Opinion MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward informational read operation. It retrieves metadata about personality types available in the system. There are no side effects, no data modification, no code execution, and no irreversible actions. The blast radius of misuse is minimal—at worst, an agent learns what personality options exist, which is non-sensitive configuration information.
From the tool's definition Tool name 'list_personalities' and description 'List all available personality types with descriptions' indicate a retrieval operation that queries and returns information about available personalities without modifying any data or triggering external actions.
Documented attack patterns abuse exactly the kind of access list_personalities gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Second Opinion MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for list_personalities:
{
"version": "1",
"default": "deny",
"tools": {
"list_personalities": {}
}
}list_personalities is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all available personality types with descriptions. It is categorised as a Read tool in the Second Opinion MCP MCP Server, which means it retrieves data without modifying state.
Register the Second Opinion MCP server in PolicyLayer and add a rule for list_personalities: 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 Second Opinion MCP. Nothing to install.
list_personalities 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_personalities 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_personalities. 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_personalities is provided by the Second Opinion MCP server (procreations-official/second-opinion). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
