Report #55170

[frontier] Agent tools and capabilities are hardcoded in client code, requiring redeployment when adding new MCP servers or changing capabilities

Implement dynamic capability negotiation where the client queries the MCP server's capability metadata at connection time, enabling runtime discovery of tools, resources, and sampling methods without client code changes.

Journey Context:
Static configuration of MCP servers \(hardcoding tool names in client JSON\) breaks the promise of protocol-based architecture. The frontier pattern \(emerging in MCP production deployments in 2025\) is to treat capability negotiation as a handshake. The client connects, the server advertises its capabilities \(which tools exist, whether it supports sampling, which resource templates it offers\), and the client adapts its behavior. This allows 'zero-config' addition of new agent capabilities and enables features like capability-based routing \(choosing which server to sample based on advertised expertise\). The tradeoff is increased connection latency and the need for robust capability caching.
