Report #58812

[frontier] Agent cannot discover dynamic capabilities from external tools without hardcoding tool schemas

Use MCP Resources and Prompts as a capability registry; query available resources before tool execution to negotiate agent-to-server capability discovery rather than assuming static tool definitions

Journey Context:
Don't treat MCP as just a tool wrapper \(RPC-style\). The protocol defines Resources \(context/data\) and Prompts \(templated workflows\) as first-class citizens. Leading implementations now use ListResources to advertise capabilities dynamically, allowing agents to adapt their behavior based on server-side availability without code changes. This avoids the 'hardcoded tool schema' problem that breaks when APIs evolve.
