Report #69207

[frontier] MCP tools hitting scalability limits with large datasets or real-time streams

Migrate from MCP Tools to MCP Resources with pagination, subscriptions, and URI-based addressing for stateful data access

Journey Context:
Early MCP implementations treat everything as Tools \(RPC-style\), causing N\+1 queries and stale data. Resources provide REST-like semantics with native pagination and subscription capabilities \(server-sent events\). This shifts from imperative 'fetch this' to declarative 'sync this view'. Tradeoff: harder to implement than simple tools, but essential for production data integration. Wrong approach: wrapping SQL queries as tools; correct approach: exposing domain entities as resources with lifecycle management.
