Report #35935

[frontier] MCP server only exposes tools, missing the context injection and prompt template primitives

Implement MCP Resource providers to expose contextual data the host reads on-demand, and MCP Prompt templates for reusable parameterized instruction patterns. Resources are host-pulled \(ambient context\), tools are host-pushed \(explicit invocation\)—use both.

Journey Context:
Most MCP implementations use only the Tools capability, treating MCP as a fancier function-calling wrapper. But MCP's Resource and Prompt primitives solve different problems. Resources let the model have ambient awareness of files, schemas, or API data without requiring explicit tool calls—critical for context the model should always see. Prompts let you server-side template instruction patterns with arguments, creating a single source of truth that prevents prompt drift across clients. The mistake is equating MCP with tool-calling; it is a three-pronged protocol and using only one prong leaves the hardest problems \(context management and prompt consistency\) unsolved.
