[frontier] Hardcoded tool registries make it impossible to dynamically compose agent capabilities or share tools across agent runtimes

Use MCP \(Model Context Protocol\) servers as a capability discovery and composition layer. Deploy tools as MCP servers that advertise their schemas. Agents discover available capabilities at runtime rather than having them hardcoded. Compose multiple MCP servers to give agents access to evolving toolsets without code changes.

Journey Context:
The first generation of agent tooling hardcoded tool definitions in the agent's system prompt or configuration. This is brittle: adding a tool requires code changes, and tools can't be shared across different agent frameworks. MCP was introduced as a standard protocol for connecting AI models to tools and data sources, but most early adopters used it as a simple tool-calling transport. The frontier use is as a capability discovery layer: MCP servers advertise their capabilities via standardized schemas, and agents \(or orchestrators\) discover and compose these capabilities at runtime. This enables: \(1\) dynamic toolset composition — add a new MCP server and all connected agents gain its capabilities, \(2\) cross-framework interoperability — any MCP-compatible agent can use any MCP server, \(3\) capability scoping — expose different MCP servers to different agents based on their role. The tradeoff is added infrastructure complexity, but this is the same tradeoff that service registries solved for backend systems.
