[frontier] hardcoded tool registries make agents brittle and unable to adapt to new capabilities at runtime

Use MCP servers as a dynamic capability discovery layer. At agent initialization, query available MCP servers for their tool lists, resource templates, and prompt capabilities. Build the agent's tool registry at runtime from discovered capabilities rather than static configuration. When a new MCP server comes online, the agent can discover and use its tools without code changes or redeployment.

Journey Context:
The standard approach is to define all tools statically in agent code or config files. This works for demos but breaks in production: different environments expose different tools \(dev vs staging vs prod\), new integrations require code changes, and tool schemas drift out of sync with actual APIs. MCP was designed to solve this—the specification includes a discovery protocol where clients list available tools, resources, and prompts from servers dynamically. The frontier pattern is using MCP not just as a tool-calling transport but as a capability mesh: agents discover what they CAN do at runtime rather than being told statically. This enables environment-adaptive agents that work with whatever MCP servers are available. The tradeoff is that dynamic discovery requires more robust error handling \(a discovered tool might be temporarily unavailable\) and you lose compile-time type safety on tool inputs. But the benefit—agents that adapt to their environment without code changes—outweighs these costs. People commonly get this wrong by treating MCP as just a fancy function-calling wrapper and hardcoding the tool list anyway, missing the discovery protocol entirely.
