[frontier] How do I avoid hardcoding which agent handles which task in a multi-agent system?

Use MCP Tool schemas as capability advertisements: each agent exposes an MCP server describing its tools/capabilities, and a router agent queries these schemas at runtime to decide which agent to delegate to, enabling dynamic service discovery.

Journey Context:
Multi-agent systems traditionally use static routing \(supervisor agent knows all workers\). This breaks when adding new agents or when capabilities overlap. Some use vector similarity of descriptions, but this is fuzzy. The frontier pattern leverages that MCP requires servers to expose tool schemas \(name, description, parameters\) via \`tools/list\`. Agents now run MCP servers \(not just clients\), advertising their capabilities. A 'router' agent queries the MCP endpoint of candidate agents, reads the JSON Schema of available tools, and uses that to generate the exact tool call \(delegation\) to the appropriate agent. This turns agent discovery into a protocol-level schema negotiation, eliminating hardcoded routing tables.
