The request names MCP itself, so the answer is about the Model Context Protocol. None of the candidates is the protocol's own reference; mcp.build 1 hosts ready-to-connect open-source MCP servers, mcp.film 2 is a curated directory of MCP servers for AI filmmaking, and mcp.ai 3 is an MCP marketplace and connector toolkit. Since the request is about creating a declarative agent and no platform is stated, the choice of tool depends on which platform the agent will run on.
A question back: Which platform or agent runtime will the declarative agent run on, and what should it do?
