Oracle Fusion HCM MCP

Local Oracle Fusion HCM MCP server backed by normalized Oracle REST API catalogs.

The current server intentionally has no caller authentication. It binds to 127.0.0.1 by default for local and demo-pod development. Oracle credentials, when configured, are used only by the outbound Oracle connector.

• Single-copy MCP embedded resources for binary catalog, Publisher, and report artifacts

• Privacy-conscious audit events

• Sanitized API artifact registry

• Official Oracle OpenAPI importer and normalized operation catalog

• MCP Streamable HTTP server with hcm_catalog_search
