[FEATURE] SDK Support for Enabling/Disabling MCPs

Preflight Checklist

• [x] This is a single feature request (not multiple features)

Problem Statement

The Claude Code CLI allows a user to manage their MCP servers using the slash command /mcp [enable|disable server-name]]. This type of control is absent in the Claude Code SDK.

While the SDK allows passing a list of MCP servers via the mcpServers option when calling query, we use presets in the SDK to automatically load MCP servers based on users' environments so we have no control over enabling/disabling servers selectively.

Proposed Solution

Support for a session-scoped method that allows a developer to enable/disable a connected MCP server.

Alternative Solutions

The SDK does not support any form of MCP management in its current state.

Priority

High - Significant impact on productivity
