MCP Sampling Support in Zed

[yaonyan]

I'd like to request MCP Client Sampling support for Zed, following the MCP Specification.

What it enables:
This allows MCP servers to call AI models through the Zed MCP client, enabling intelligent agentic tools that can reason and make decisions.

Example use case:
A background code style checker that monitors file saves, uses AI to analyze violations in project context, and works asynchronously without blocking the workflow.

Benefits:

• No separate API keys needed for MCP servers
• User controls which model to use
• Provides feature parity with VS Code (already supported)

Appreciate that Zed has been experimenting with innovative agent feature like Agent Client Protocol – exciting to see MCP Sampling as another interesting feature to be added! 🚀
