Load an operation by path and method
AI agents call load-api-operation-by-path-and-method to retrieve information from MCP OpenAPI Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns API operation metadata (likely OpenAPI operation objects) based on path and HTTP method parameters. It performs read-only access to the API specification catalog without modifying, executing, or deleting anything. The narrow blast radius (returns schema/metadata only) justifies low severity.
From the tool's definition Tool name 'load-api-operation-by-path-and-method' and description 'Load an operation by path and method' indicate retrieval of API operation metadata.

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP OpenAPI Server, and nothing reaches the server without passing your rules. This is the rule we recommend for load-api-operation-by-path-and-method:
{
"version": "1",
"default": "deny",
"tools": {
"load-api-operation-by-path-and-method": {}
}
}load-api-operation-by-path-and-method is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
