As a leading AI development tool, Claude Code has recently released two highly anticipated updates. These innovative features aim to optimize the user experience, reduce context usage, and enhance interaction flexibility. According to the latest information, these two updates have been gradually rolled out to users, marking another major advancement in Claude Code's tool management and prompt interaction capabilities. The AIbase editing team has compiled relevant information and provided professional insights for developers.

 MCP Tool Search: Dynamic Loading, Say Goodbye to Context Bloat

The MCP tool search feature introduced by Claude Code is seen as the core solution to the problem of excessive context window usage by tool descriptions. In the past, when users installed a large number of MCP tools, these tool descriptions were preloaded, consuming 20k-60k or more tokens during startup, which severely affected actual coding space.

The new feature achieves optimization through a "lazy loading" mechanism: the system automatically detects whether the MCP tool description exceeds 10% of the context window. If it does, it switches to search mode, dynamically loading only the relevant tools when needed. This not only reduces token consumption by up to 85%, but also supports an unlimited expansion of the toolset—connecting 100+ tools will not consume resources in advance.

In addition, for creators of MCP servers, it is particularly important to pay attention to the "server instructions" parameter to ensure that the tools can start and be searched properly. This feature is now the default mode, and users can manually adjust it (e.g., by setting ENABLE_TOOL_SEARCH=true) to further improve the accuracy and efficiency of tool discovery. This update makes Claude Code smarter when handling complex tool ecosystems, and developers report that it has completely changed the "token bloat" pain point.

 Tab Key for Additional Information: Flexible Handling of Prompts, Saying Goodbye to Dilemmas

Another highlight is the Tab key supplement information feature when accepting or rejecting prompts. This innovation targets a common issue users face during prompt interactions: when the AI-generated prompt is partially correct and partially incorrect, users often struggle to decide whether to accept or reject it entirely, leading to low efficiency.

Now, using the Tab key, users can directly add additional information when accepting or rejecting, allowing for precise adjustments. For example, after a prompt suggestion appears, pressing the Tab key enters edit mode, quickly modifying inaccurate parts without restarting the conversation. Combined with the Enter key for immediate submission, this further optimizes interaction fluidity.

This feature has also been extended to Tab completion for shell commands, offering more intelligent command suggestions in bash mode. Developers say this update greatly alleviates the dilemma of "partially correct and partially wrong" scenarios, making prompt handling more human-centered and improving overall development efficiency.

AIbase Comment: These updates from Claude Code reflect the evolution of AI tools toward greater efficiency and user-friendliness. The MCP tool search solves the bottleneck in scaling tool management, while the Tab key supplement enhances the flexibility of human-computer collaboration. Looking ahead, with more plugins and CLI optimizations, Claude Code is expected to become a benchmark in the AI coding field.
