Claude docs changes for March 6th, 2026 [diff]

Executive Summary

Remote Control is now available on all plans (Pro, Max, Team, Enterprise), no longer limited to Max/Pro research preview
VS Code gained three major features: an Activity Bar sessions panel, full markdown plan document view with inline comment support, and a native MCP server management dialog via /mcp
ZDR eligibility clarified for web search/fetch tools: the dynamic filtering versions (web_search_20260209 / web_fetch_20260209) are not ZDR-eligible by default, but can be restricted to direct-only invocation to qualify
Compaction now available on Amazon Bedrock, Google Cloud Vertex AI, and Microsoft Foundry (previously Claude API only)

[VSCode] Added Spark icon in VS Code Activity Bar that lists all Claude Code sessions, with sessions opening as full editor tabs
[VSCode] Added full markdown document view for plans, with support for adding inline comments to provide feedback before Claude begins
[VSCode] Added native MCP server management dialog — use /mcp in the chat panel to enable/disable servers, reconnect, and manage OAuth authentication without switching to the terminal

Improved compaction to preserve images in the summarizer request, allowing prompt cache reuse for faster and cheaper compaction
Improved /rename to work while Claude is processing, instead of being silently queued
Reduced prompt input re-renders during turns by ~74%
Reduced Remote Control /poll rate to once per 10 minutes while connected (was 1–2s), cutting server load ~300×

Fixed API 400 errors when using ANTHROPIC_BASE_URL with a third-party gateway — tool search now correctly detects proxy endpoints and disables tool_reference blocks
Fixed API Error: 400 This model does not support the effort parameter when using custom Bedrock inference profiles or other non-standard model identifiers
Fixed empty model responses immediately after ToolSearch
Fixed prompt-cache bust when an MCP server with instructions connects after the first turn
Fixed clipboard corrupting non-ASCII text (CJK, emoji) on Windows/WSL by using PowerShell Set-Clipboard
Fixed voice mode failing on Windows native binary with "native audio module could not be loaded"
Fixed push-to-talk not activating on session start when voiceEnabled: true was set in settings

Prompt examples in code blocks no longer include a leading > prefix, matching actual CLI usage

Added Activity Bar entry point: the Spark icon is now always visible in the left sidebar to list all sessions; clicking opens a session as a full editor tab. [line 37] [Source]
Plan mode in VS Code now automatically opens the plan as a full markdown document where you can add inline comments before Claude begins. [line 66] [Source]
MCP server config capability in VS Code updated to "Partial": add servers via CLI, manage existing servers with /mcp in the chat panel. [line 249] [Source]
Documented new /mcp management dialog in VS Code for enabling/disabling servers, reconnecting, and OAuth without switching to the terminal. [line 297] [Source]

Updated Klaviyo MCP URL to include ?include-mcp-app=true
Smartsheet entry updated to require a user-specific URL instead of a fixed endpoint
Added PostHog MCP server (query, analyze, and manage PostHog insights)
Various reordering of MCP server entries in the directory

Remote Control is now available on all plans (Pro, Max, Team, Enterprise) — previously restricted to Max plan as a research preview. [line 3] [Source]
Team and Enterprise admins must first enable Claude Code in admin settings before users can access Remote Control. [line 18] [Source]

Added Activity Bar sessions list entry (Spark icon always visible in the left sidebar)
Plan mode now automatically opens as a full markdown document with inline comment support
MCP server config updated to "Partial" — add via CLI, manage with /mcp in the chat panel
Documented /mcp management dialog for managing servers and OAuth from within VS Code

Code example comments updated to clarify that max_tokens=64000 is a practical non-streaming ceiling — Opus 4.6 supports 128K output tokens with streaming enabled. [line 275] [Source]

Memory tool moved from the "Server-side tools" table to the "Computer use" (client-side) tools table, reflecting that it operates client-side. [line 50] [Source]
Compaction now listed as available on Amazon Bedrock (Beta), Google Cloud Vertex AI (Beta), and Microsoft Foundry (Beta) in addition to the Claude API. [line 51] [Source]

Smartsheet entry updated to require a user-specific URL instead of a fixed endpoint
Added Gusto MCP server (query and analyze Gusto payroll/HR data)
Added Yardi Virtuoso MCP server (real-time Yardi data and insights)
Various reordering of entries in the MCP server directory

Corrected Java SDK method name from outputFormat(Class<T>) to outputConfig(Class<T>). [line 122] [Source]

Clarified ZDR eligibility: the basic tool version (web_fetch_20250910) is ZDR-eligible, but the dynamic filtering version (web_fetch_20260209) is not ZDR-eligible by default because it relies on code execution internally. [lines 10-16] [Source]
Added instructions to disable dynamic filtering ("allowed_callers": ["direct"]) to use web_fetch_20260209 with ZDR.

Clarified ZDR eligibility: the basic tool version (web_search_20250305) is ZDR-eligible, but the dynamic filtering version (web_search_20260209) is not ZDR-eligible by default. [lines 7-16] [Source]
Added instructions to disable dynamic filtering ("allowed_callers": ["direct"]) to use web_search_20260209 with ZDR.

Web Search and Web Fetch ZDR eligibility entries updated with version-specific details, noting that dynamic filtering versions are not ZDR-eligible by default. [lines 99-101] [Source]
Section renamed from "Fully ZDR-eligible" to "ZDR-eligible" and language throughout changed from "covered by ZDR arrangements" to "ZDR-eligible" for consistency.
