Report #46156

[frontier] MCP servers implemented as static tool wrappers causing tight coupling

Use MCP Resource Templates with URI templates \(e.g., /databases/\{id\}/schema\) to expose discoverable capabilities, shifting from imperative tool-calling to declarative resource subscriptions

Journey Context:
Early MCP implementations wrapped existing functions as 'tools', creating brittle RPC-style coupling. The 2025-03-26 MCP specification introduces Resource Templates, allowing agents to discover and subscribe to dynamic resources via URI templates. This architectural shift enables capability negotiation: agents query available resources, subscribe to updates, and treat tools as side-effect operations on resources. This decouples agent logic from specific tool implementations, allowing hot-swapping of backends without changing agent code.
