Get an opinion from the default available AI model (automatically selects best available service)
AI agents call get_default_opinion 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 tool queries external AI services to fetch opinions/feedback. It is purely informational and read-only—no data is created, modified, deleted, or irreversibly changed. The 'automatically selects best available service' phrasing indicates automatic routing logic rather than code execution on the user's system.
From the tool's definition Tool name 'get_default_opinion' and description 'Get an opinion from the default available AI model' indicate querying/retrieving data without modifying state.

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 get_default_opinion:
{
"version": "1",
"default": "deny",
"tools": {
"get_default_opinion": {}
}
}get_default_opinion is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
