Question

You are building developer productivity tools using the Claude Agent SDK. The agent helps engineers explore unfamiliar codebases, understand legacy systems, generate boilerplate code, and automate repetitive tasks. It uses the built-in tools (Read, Write, Bash, Grep, Glob) and integrates with Model Context Protocol (MCP) servers.

After adding an MCP server with specialized code refactoring tools (extract_function, rename_variable, inline_function), You notice the agent still uses basic text manipulation via Write and Bash sed commands for refactoring tasks. The MCP server is connected and healthy. Examining the configuration, you find each MCP tool has a minimal description like “extract_function: Extracts a function from code.”

What’s the most effective way to improve adoption of the MCP refactoring tools?

Accepted Answer

D. Enhance the MCP tool descriptions to explain when each tool is preferable to text manipulation and clarify expected inputs and outputs.

Answer

A. Implement a request classifier that detects refactoring intent and automatically routes those requests to the MCP server before the agent processes them.

Answer

B. Remove the Write tool from the agent’s configuration for refactoring sessions so it must use the MCP tools for code modifications.

Answer

C. Accept this as expected behavior since simpler tools like sed are more predictable than specialized refactoring tools.
