[frontier] MCP server tools lack guidance on how the agent should use them together

Use MCP Prompts to expose named, parameterized prompt templates alongside your tools. MCP Prompts let servers ship not just capabilities \(tools\) but also behavioral instructions \(how to combine tools, what order to call them, what to do with results\). Clients discover prompts the same way they discover tools.

Journey Context:
When you install an MCP server, you typically get tools but no instructions on how an agent should orchestrate them. The agent must figure out from tool descriptions alone that it should call 'list\_files' before 'read\_file', or that 'search\_code' results should be filtered before passing to 'edit\_file'. MCP Prompts solve this: servers expose named prompt templates \(with arguments\) that encode best-practice workflows. For example, a code-review MCP server might expose a 'review\_pr' prompt that orchestrates multiple tool calls in the right order with the right context. This is the composable-agent-behavior pattern: capabilities and their usage instructions travel together. Without prompts, every client agent must rediscover optimal tool usage from scratch. With prompts, the server author encodes their domain expertise directly. This is emerging as the key differentiator between toy MCP servers and production ones.
