AON MCP
Use AON MCP to search and refine offers from your AI client. When MCP access is provisioned for your account, start with Connection Setup for client configuration and an end-to-end request.
No access yet? Run the Public Test Sandbox to inspect the Query contract. The Sandbox cannot configure MCP access or replace an issued credential.
Hosted MCP v1.0 production status
The Hosted MCP runtime owner has certified this production deployment as the
fixed AON v1.0 projection. The certification records an authenticated
production observation: initialize.serverInfo.version="1.0.0", tool-response
data.protocol_version="1.0", and the exact five-tool runtime surface. It is
bound to the deployed source, production configuration, immutable image, and
the certification digest; it is not a certification of REST, OpenAPI, SDK, or
Portal surfaces.
